Awesome job! Great video!! I'm considering replacing my spark plugs very soon. Now I'm thinking of doing the valve cover gasket because they have never been done before. 1777,800 miles on my 007 IS350. I'm a big believer in doing maintenance before it needs to be done only because it gives me pice of mind knowing that it's been done!! Thank you. Jeff Grant Mooresville NC USA
Thank you for this video! Saved a bunch of money. One suggestion… If the spark plug caps don’t fit, most likely you didn’t remove the metal ring from the previous cap. Use a blade screw driver to pry the old one out.
Thank you so, so much - I've been thinking about taking the covers off to tighten the bolts on the cam gears, since it started rattling a week ago and I read that the bolts may come loose and cause oil to leak back into the engine and not stay inside them :) .
i got mine done today u got to have a lot of patience to do that job but im glad i safe some $$ thanks for the video and the bolt by the driver side was really a b
@@HelpingHandAutoRepair i did my starter too last week so i decide to fix everything to replace the starter too is not a joke the top bolt din t want to come out i had to cut it it was very rusty but got it done
@@HelpingHandAutoRepair 3 hours is not bad at all especially given that I've spent entire days just replacing suspension parts (especially with rusty fasteners.) Looks like I should plan to do this and my water pump in the same day since some of the same stuff needs to be worked around and less risk of spilling coolant from disconnecting hoses if it's already drained.
Especially working outside, I was doing some work last week and we've already got leaves falling off our trees and I had to clean them out of the engine bay before closing the hood. I don't want to think of one clogging an intake valve or getting into a cylinder.

Very helpful indeed; however as you reiterated patience is the key to successfully completing these jobs. While I'm at it, how many camshaft timing oil control valves are they on these RWD 2008-2012 V6 IS250/350 engines?
About to do this. Really good video. Wish you showed when you were taking the valve cover off and putting it back on so we can see how difficult or easy it comes on or off. Did you have to use some kind of sealant on the gasket? Thanks again. This is really helpful.
Do you have to take off intake manifold just to get off the right rocket cover? I know you need to get both off but what about just the drivers side one?
Awesome Video... Thank you! I bought the gasket set this morning. I just happened to stumble opon your video. You just made my life easier😊. Very descriptive and verbatim. You deserve all good things that happen to you😎👍 Thank You!
Very helpful video. I was able to do for the first time. I know its been a while but anyway do you remember if you had to prime the fuel lines? My car won't start after putting everything back. It looks like fuel is not getting there. Thanks a lot
You shouldn’t have to, but valve cover gaskets are normally sold as a pair. If one side is leaking, chances are the other side isn’t far behind. May as well replace them both.
Great video man, nice and clean video. Would you mind sharing the list of Tools especially the one you used at the back near the high pressure fuel pump. thanks
sunny ponappa badalera Hello, honestly I couldn’t remember every single tool I used in the video. I will say that you need a set of metric 3/8” sockets with a 3 and 6 inch wobble extension. The high pressure pump is held on by two 12mm nuts that can be accessed very easy from the top. As well as the metal pipe that heads towards the back of the motor. It is held on by two 10mm bolts that should be able to be accessed pretty easilyz
Since somebody today might be wondering according to the Factory Service Manual it's 18 ft-lbs for the fuel pump and 7 ft-lbs for the flange holding that fuel line in.
It was a pain in the ass! I had to remove the lower intake plenum to get to it, which wasn’t hard at all just remove the bolts that come with it and might as well replace the gaskets from the lower intake manifold
Great video, very helpful, thanks. I have changed spark plugs but my issue is an engine rattle that got to the point engine would just stop (shut down). Any tips how I can access/replace the vvti controller/ timing chain?
Your videos are a great help and they are very easy to follow along. It's awesome that you are wiling to help people like this! I also have a question regarding this procedure. Along with replacing the spark plug tube seals do you recommend replacing any other seals while having the covers off? Reading the forums, where I actually found your video, I ran across people saying that there is o rings in the valve cover for oil passages to the camshaft. Could you clear that up for me please? I looked at the parts diagrams on the dealer sites and such but I only found CAMSHAFT BEARING CAP OIL HOLE GASKET, could this be what it is meant? I also ran across CAM TIMING OIL CONTROL VALVE, but again it does not point it out on the diagram? My car is approaching 120k and it seems like something else comes up as soon as I fix one thing so I am just trying to get ahead if I can and prevent re-doing the same task twice lol. Thank you for all your help!
Goran Lulic Yes there are small o-rings on the underside of the valve cover. I don’t recall these coming with the valve cover gasket kit. Then again this was a while ago. It very well may have come with my gasket set. They should be able to be found pretty easily at any local parts store or the dealership. Thanks for the kind words!
@@HelpingHandAutoRepair I gotcha, thought I'd check and see if it rang any bells. I may go by the dealership and see if they do in fact come with it. Thanks for replying so fast!👍👍
Great video I am doing that repair on my car 2006 Is350 and I am having one hell of a time getting that fuel pump or regulator out-of-the-way. on my car the coolant lines are directly on top of it so I can’t just pick it up I’m having to remove additional items. Any additional wisdom on this
Marshall Kendo I can only assume the IS engine bay is slightly smaller than the GS I am working on in this video. If there is a way to detach the coolant lines via a bracket that would be able to give you more wiggle room, that would be the best way. You do need to loosen and remove the 10mm fasteners I mentioned in the video on the back of the motor and that little rubber hose I also mentioned. Worse case is you will need to disconnect the coolant lines that run on top of the it. I couldn’t imagine Lexus making it this difficult for IS owners but you never know.
Thanks again brother. Took me 4.5hrs to complete this job. You were not kidding about the driver's side cover being a pain. Bolted everything back together only to forget the two cooler lines lol @@HelpingHandAutoRepair
When you open the hood looks nice bcuz of the plastic cover😁.. by the time you take off the plastic What a bulky engine 🤔🤔.. i rather buy a integra more easy to fix it than the lexus... you did a good job 🤗🤗🤗
Great video. Im planning to do mine as well. This is helpful. How do u remember where everything should be putting it back together ie. screws, and connectors, etc?
I just fought this on my 01 4runner with the 5vz motor. Took me about 6 hours. As helpful as this is it also is increasing my likelihood of letting someone else do it. I dont have the patience to do this again lol
Lol yes V6 FWD or RWD setups are just irritating on these Toyotas. Simply because you have to take the intake manifold off. If the intake manifolds were designed like some other car manufacturers (like Mercedes for instance) then you don’t need to take the manifold off at all. They are very easy to do.
@@HelpingHandAutoRepair exactly! My 5vz is easy for the passenger side because you dont have to take off the intake but the driver side requires both upper and lower intake plenums and the throttle body and all vacuum lines and you still fight the wiring harness like the 2gr. I could definitely tackle this job myself but honestly for times sake and frustration I just dont see it being worth it lol
@@jeffumbach that's true. I just know working on these motors is so much work compared to the 5vz-fe motor lol. Just a lot of stuff in your way every time you turn around
I believe I did on certain areas where the timing cover meets the front of the head and wherever there are humps or such. Sorry this was done awhile ago. I tend to just put RTV wherever I think a leak could develop. Not a lot but just a little bit.
I just wanted to ask did you use the gasket maker ( toyota seal packing black or three bond or similar product) like area close to timing chain. Thanks
Haydn Ciepiela Sorry, I don’t recall that I did. However if you would like to simply find the fuse (owners manual or online diagram) that operates the fuel pump. Start the car and pull it out while it’s running and then your system will not be pressurized anymore 👌🏽
Great job very informative and detailed and neat, my question is the intake manifold gasket has other name plenum gasket or that’s different , because I’m getting a new spark plugs with ignition coil and the mechanic ask me to bring plenum gasket and also I’m bringing two engine cover gasket since I have seeping in the left one, so he recommend me doing it at the same time thanks again for your vid
There is a plenum gasket/intake manifold gasket. They usually are one in the same. However most V6 engines will have an upper and lower intake manifold/plenum gasket. Shouldn’t need the lower gasket since you don’t even have to take that off. The upper gasket should be all that’s needed. Unless he or you want to replace the lower one.
@@HelpingHandAutoRepair great thanks for the fast respond, but do I really need to change the lower one? Or the upper should be enough ? Also I saw your mentions the spark plugs tube gasket Do you recommend me replacing them since I have 111,500 on gs350 ? are yours was in a good shape ? Thanks again
You don’t need to change the lower one. Normally when you buy a valve cover gasket set, it will come with tube seals in the kit. If not, you need to buy them. That is considered “apart of” a valve cover gasket replacement. The car in this video was a customer’s car. I honestly can’t remember what they gave me in regards to parts since it was so long ago. I am quite confident that I would have told them to replace the tube seals.
@@HelpingHandAutoRepair I’ll replace them all not a big of a deal they’re very cheap anyway from lexus dealer. Thumbs up my friend have a blessing Sunday 🎊
Any suggestions on putting the spark plug tube seal on seem like mines doesn’t wanna fit I even used a rubber hammer and yes the seal goes to my car lol
Ann Borromeo I’m sorry as this was a little while ago. I think I had to either leave the bolt in while removing the whole pump or maneuver it out some way. I honestly don’t remember but I know I did remove the pump.
Looks like you have to take the actual plenum off or loose just to get that bracket off because one of the 10mm is directly under a sensor what a poor design
Hey man, thanks for the video. Very helpful. This will be my second time tackling this job. I have a problem tho, with mines I’ve had a p0420 code and it runs pretty rough. It’s been like that for a while and two months or so ago I swapped the two cats under front but I still have the code and I smell the egg smell. Do you think I would need to swap the rear cats?
If you didn’t replace the cats with new units, you will have the code and the smell until you replace the cats. The cats are most likely clogged causing it to run rough.
Scott c Yes on the front of the heads you will notice there is a timing chain front cover that attaches to the side of the FRONT on the cylinders beer heads. I just cover that seam where the two meet. I also put a dab in the back on the lowest points of the valve cover.
Ponyboy Yes. Unfortunately you need to pull off the valve cover to replace that seal. Might as well get the valve cover set and just replace both sides as I show you in this video.
Thank you for the quick response!!! I figured that’d be the issue but wanted to make sure 100% thats what it is. Im uploading a video soon showing the plugs. Do check it out and confirm ua-cam.com/video/ZjgObHV3gDY/v-deo.html The Gasket kit I'm getting is below. Please confirm that aswell www.thewrenchmonkey.ca/products/auto-parts/fel-pro/vs50690r/
Ponyboy by your video I am not convinced that you have bad tube seals. The coil actually looks pretty dry. The oil on the threads of the spark plug appears to be ok. As you see the tip of the plug appears to be in ok shape. The coil looks dry and just dirty. It would be wise to read the codes (if you have a CEL on) and then you can try and pull just those coil packs and inspect them for lots of oil on the outside of the coil pack boot as well as oil in the inside of the boot. The valve cover set you have selected looks fine.
Ponyboy I would first clean off the threads of the plug with brake cleaner real good and then reinstall the plug and make sure you torque it down completely and make sure that it is completely seated. Then inspect the bottom of the coil boot (the spring inside should be dry) for excessive WET oil. If it is ok reinstall the coil pack. If the problem still persists on cylinder 6 then take that coil and swap it to the other side of the motor (ie the other head) and install it and see if the misfire follows that coil. If it does then you have a bad coilpack. If it doesn’t follow and stays on #6 then get back to Me.
Thank you again. I will follow your steps and re-torque the plugs. The oil on the coil was minimal so it didn't show on the video properly. However, if you see the ends of boot between 0:30 - 0:35 you can see the ends of coil shiny. But there was oil on the coil 100%. Thanks again! I'll get back to you after performing your suggestions.
I wonder If the tube seals where but on right you had them facing up but now won't slide in easy threw spark plug tubes I got them in by using plastic pry bar any ideas I looked at yours and put mine in just like you had them facing??? Help lol
Same thought, the FSM directs them to be covered with tape. Fishing something out of there that got dropped in would be a pain and if working outdoors something is likely going to blow by and fall in there.
I started on the passenger side, eveything was moving along until I accidently stripped the threading on the banjo fitting hole on my GS350. Dont tighten down the perimeter bolts on the 17mm banjo fitting is in first...
Hey man, thanks for sharing this issue. I’m in the process of putting back the banjo bolt (Driverside) and I’m having a hell of a headache to tighten that banjo bolt back in place. Any advice?
@@marcomelo8576 great job man! I assume you own an IS? Noticed the very tight space around his banjo bolt on my IS. Won't be doing this job any time soon since my valve covers don't seem to leak anywhere but I'm mentally preparing for some big jobs in the future since my IS250 is at 200k miles now
on the two bolts that go to the fuel rail (behind the intake manifold) how did you get them off? I’m able to get one off but the other is kind of under part of the manifold. I can’t seem to get my tool onto it.
I keep getting p0455 and p0451 low evap i changed all the intake mainfold gaskets and changed the valve covers and spark plugs weirdly enough the evap hose connect to the purge valve wasn’t even connected when I started when I finished I felt like I was mixing up my breather tube and brake booster line it’s startes and cold starts smooth but when rpm goes under 1000 car won’t stay started
What are the 2 hoses above the fuel pressure regulator? I have an IS250 and those 2 hoses are directly above the regulator and I may need to disconnect one of them.
Bank 1 will be passenger side if you have the 3gr engine. Circuit A is Intake sensor. So if you are looking at the engine, in the front of the engine on the top of the valve cover on the passenger side cylinder head. There should be two sensors. One is for the exhaust cam, one is for the Intake cam. The sensor closest to the center of the engine will be the one.
Helping Hand Auto Repair thank you so much! Got code P0340 camshaft position censor bank 1 A circuit along with P0335 crankshaft sensor. Going to check wires/connection. If good going to replace camshaft sensor. Car will not turn on at all. 2008 Lexus GS 350 RWD
JustJay 0312 well you need to replace the crank sensor as well. I believe that is near the ac compressor on the driver side of the engine on the bottom or near the bottom of the engine. I don’t remember if you need to remove the ac compressor or not to get to it.
Just curious, im replacing my fuel pressure sensor on my 07 gs350. Are there any bolts behind the plenum, or are they simply all over the top? And thanks, I'm gonna subscribe
Should just be the bolts on top. You would need to watch that portion of the video again tbh. This was a while ago and I don’t remember everything exactly.
Will this fix a car that has failed the combustion test on the coolant? I took it to Toyota and the basically said that I would need a new engine because I either have a crack in the block or a blown head gasket. If I open up my engine like this would I be able to tell which is which?
In the middle of doing my 06 is350 right now. I unbolted everything on the driver's side valve cover but it's still stuck. Any advice on lifting it or loosening the gasket?
double and triple check there isn't a bolt still holding it down. Also if you followed the video completely, maybe you missed a bolt or bracket by chance. Sometimes they are stuck pretty good and you can get a small flat head screw driver to persuade the valve cover to come up and off. You have to be careful you don't gouge the aluminum head sealing surface.
This is a useful video. Thanks for your time. I have a question about the lexus gs300 3rd generation . I have the code P0420 which means catalytic converter bank 1 is broken or something like that and I supposed that the spark plugs are bad so I changed them but the one spark plug from 5th cylinder had a little bit oil on . I changed the air filter too. I cleaned the air mass sensor also the body assy throttle but the car runs bad and makes vibration . I made a diagnosis to the car and says that the oxygen sensor and catalytic converter are bad. Could you help me please?
Oh ok. Well I assume your car has a decent amount of miles on it? P0420 codes are indicative of a catalyst that is getting old. It could also by chance be a bad down stream O2 sensor on bank 1. This is not normally the case though as the catalyst is usually the culprit. If you have a scanner that can read live data, I can help you determine if the o2 sensor is bad. As far as the oil on the spark plugs, you need to replace the valve cover gaskets to solve that. It is most likely running rough because it is misfiring due to the oil on the plugs.
The car has around 118.000 miles. I thought when I change the ignition coil of that spark plug which has oil on it maybe it will be ok if the problem will persists maybe I will check the catalytic converter with an endoscopic tool.
If there is oil on the coil then you need to replace the valve cover gaskets as shown in this video. Otherwise you will continue to have a poor running car because the spark will be arcing off into the pool of oil instead of going to the spark plug. This car must have been driven like this for a little while because now you have the 420 code which is being made worse by driving the car with a misfire. Fix the misfire first. The catalyst is getting ruined or may already be ruined.
Same thing happened to me, but I was able to get driverside loosed with a 17mm 12 point closed wrench. For the passenger side I used a 17mm socket with with a 1/2 extendable ratchet to loosen it up.
Any tips for the gs 350 model? The working room behind the intake manifold and throttle body are extremely limited. The intake manifold is a slightly different design. The throttle body and intake manifold are closer to the rear
2008. I got the intake manifold off and started loosening the driver's side cover but I'm worried about the passenger side with that fuel pump or whatever that thing is. Those two thicker coolant lines that are behind your fuel pump are directly above the fuel pump in my model, going to try and wriggle it out from underneath them today
Hey man great video. I'm contemplating doing this on my 2006 RWD IS250 which I think has seeping oil from both side cam covers. It's been like that for a good few years. Does it effect anything if I was just to leave it seeping? And clean it once in a while?
John Roberts No it doesn’t other than smelling oil burning on the stock exhaust manifolds. This smell can enter the cabin while using the fan inside if you have outside air selected. It’s more annoying then anything really. Also you will need to keep an eye on your oil level. As it will gradually lower the oil level.
Same problem here john..did you fix it ..I have same is250 rwd 145k km and it's leaking from multiple places on both side of valve cover ..should I fix it now because the car give that smell often when I push it past 120kmh
You definitely should try and have it replaced or do it yourself. The smell is just annoying. Plus you are losing oil over time and we all know what happens to engines that have no oil.

That varies tremendously based on where you live. What I would suggest someone pay in my area is around $500-600

Worse case is you will need to disconnect the coolant lines that run on top of the it. I couldn’t imagine Lexus making it this difficult for IS owners but you never know.
That’s the approach I am going to take. Of coarse the nut for the bracket is tough. Once it’s loose I think I can push them out of the way
@@marshallkendo7095 how'd you get around this
Michael Lavin I did have to take it off but it was not to bad just have to take your time with it
On the one I worked on I had to remove both the intake manifolds and the runners just to get the second 10mm bolt off to move that hose out
How long should this take with someone who has experience working on cars?
Diaz Ohana mau loa probably around 1-1/2 to 2 hours if moving quickly
@@HelpingHandAutoRepair thanks brother...this help to plan my day on the weekend to get this done!
Diaz Ohana mau loa do it! You got this 💪🏾
Thanks again brother. Took me 4.5hrs to complete this job. You were not kidding about the driver's side cover being a pain. Bolted everything back together only to forget the two cooler lines lol @@HelpingHandAutoRepair
Diaz Ohana mau loa oh no! Glad to see you got it done and saved yourself some money in the process.
When you open the hood looks nice bcuz of the plastic cover😁.. by the time you take off the plastic What a bulky engine 🤔🤔.. i rather buy a integra more easy to fix it than the lexus... you did a good job 🤗🤗🤗
Arnold Baclig not sure why this was stated? Lol
Less clutter under the integra's hood, than what's under the plastic cover in the lexus engine bay. Lol
You think that’s bad. Keeping it clean under the covers is a real choir. 😜
Well it is a bigger engine and also more advanced than an integra engine so it would make sense that there is “more stuff.”
Hondas are much much easier to repair...
Great video. Im planning to do mine as well. This is helpful. How do u remember where everything should be putting it back together ie. screws, and connectors, etc?
Yes
I suggest you take lots of pictures if you don’t remember and you can also use ziplock bags to label bolts to remember where they go
I just fought this on my 01 4runner with the 5vz motor. Took me about 6 hours. As helpful as this is it also is increasing my likelihood of letting someone else do it. I dont have the patience to do this again lol
Lol yes V6 FWD or RWD setups are just irritating on these Toyotas. Simply because you have to take the intake manifold off. If the intake manifolds were designed like some other car manufacturers (like Mercedes for instance) then you don’t need to take the manifold off at all. They are very easy to do.
@@HelpingHandAutoRepair exactly! My 5vz is easy for the passenger side because you dont have to take off the intake but the driver side requires both upper and lower intake plenums and the throttle body and all vacuum lines and you still fight the wiring harness like the 2gr. I could definitely tackle this job myself but honestly for times sake and frustration I just dont see it being worth it lol
I'll still take this over a transverse-oriented engine where one bank is against a firewall, at least you can reach both easily in this arrangement.
@@jeffumbach that's true. I just know working on these motors is so much work compared to the 5vz-fe motor lol. Just a lot of stuff in your way every time you turn around
Do you need to use FIPG or the Toyota black rtv? I know on my 22re I had to do the halfmoons and they require Toyota fipg
I believe I did on certain areas where the timing cover meets the front of the head and wherever there are humps or such. Sorry this was done awhile ago. I tend to just put RTV wherever I think a leak could develop. Not a lot but just a little bit.
Nice video. I subbed. Leaking valve cover gaskets are what is affecting my is250 now.
Same
I just wanted to ask did you use the gasket maker ( toyota seal packing black or three bond or similar product) like area close to timing chain. Thanks
Bryan Galvez Yes, I did use black silicone. Permatex Black RTV.
May i know from where did you connect the other side red wire that connected on the battery.
This is virtually an engine work.
Hi, did you depressurize the fuel system, if so, how ? Thanks !
Haydn Ciepiela Sorry, I don’t recall that I did. However if you would like to simply find the fuse (owners manual or online diagram) that operates the fuel pump. Start the car and pull it out while it’s running and then your system will not be pressurized anymore 👌🏽
@@HelpingHandAutoRepair Thank you!!!
Hi, Thanks for the vblog. To replace the valve gasket ,it's a must using RTV silicon gasket maker together with the oem valve gasket?
It’s not necessarily needed unless you feel like making a judgment call. I didn’t use any and there isn’t a single leak.
I appreciate your prompt reply.Thanks...
chen steven Not a problem! Ask me any questions you may have.
@@HelpingHandAutoRepair i had to use some cause mine was leaking but i got an after market at advanced auto part will suggest to get the oem
How did you take the valve cover off if it’s after taking all the bolts off? What did you use to get it to come up and off the cylinder head ?
Honestly don’t remember. Probably a small pry bar or a small flat head screwdriver
@ okay thank you
Great job very informative and detailed and neat, my question is the intake manifold gasket has other name plenum gasket or that’s different , because I’m getting a new spark plugs with ignition coil and the mechanic ask me to bring plenum gasket and also I’m bringing two engine cover gasket since I have seeping in the left one, so he recommend me doing it at the same time thanks again for your vid
There is a plenum gasket/intake manifold gasket. They usually are one in the same. However most V6 engines will have an upper and lower intake manifold/plenum gasket. Shouldn’t need the lower gasket since you don’t even have to take that off. The upper gasket should be all that’s needed. Unless he or you want to replace the lower one.
@@HelpingHandAutoRepair great thanks for the fast respond, but do I really need to change the lower one? Or the upper should be enough ? Also I saw your mentions the spark plugs tube gasket Do you recommend me replacing them since I have 111,500 on gs350 ? are yours was in a good shape ? Thanks again
You don’t need to change the lower one. Normally when you buy a valve cover gasket set, it will come with tube seals in the kit. If not, you need to buy them. That is considered “apart of” a valve cover gasket replacement. The car in this video was a customer’s car. I honestly can’t remember what they gave me in regards to parts since it was so long ago. I am quite confident that I would have told them to replace the tube seals.
@@HelpingHandAutoRepair I’ll replace them all not a big of a deal they’re very cheap anyway from lexus dealer. Thumbs up my friend have a blessing Sunday 🎊
Thanks. Same to you.
Any suggestions on putting the spark plug tube seal on seem like mines doesn’t wanna fit I even used a rubber hammer and yes the seal goes to my car lol
How did you get the back 10mm nut out in the back of the fuel pressure regulator line.
Probably with much difficulty lol. I think I used a short 10mm and a wobble extension.
I had to get a 10mm crawfoot to loosen the bolt but it is still not coming out.
Ann Borromeo I’m sorry as this was a little while ago. I think I had to either leave the bolt in while removing the whole pump or maneuver it out some way. I honestly don’t remember but I know I did remove the pump.
Looks like you have to take the actual plenum off or loose just to get that bracket off because one of the 10mm is directly under a sensor what a poor design
Hey man, thanks for the video. Very helpful. This will be my second time tackling this job. I have a problem tho, with mines I’ve had a p0420 code and it runs pretty rough. It’s been like that for a while and two months or so ago I swapped the two cats under front but I still have the code and I smell the egg smell. Do you think I would need to swap the rear cats?
If you didn’t replace the cats with new units, you will have the code and the smell until you replace the cats. The cats are most likely clogged causing it to run rough.
Did you get the job done? I need to do it too.
Do you recommend using a gasket sealer?
Scott c Yes on the front of the heads you will notice there is a timing chain front cover that attaches to the side of the FRONT on the cylinders beer heads. I just cover that seam where the two meet. I also put a dab in the back on the lowest points of the valve cover.
Helping Hand Auto Repair i changed both gaskets and put everything back together. But my car won’t start. Any idea what it could be ?
@@scott3074 if you didn't depressurize the fuel pump system, you can spray brake/starter fluid in the intake while someone else cranks it
mask off k thanks . I was able to get it started . Just had to crank it a few times. I think I sprayed too much carb cleaner.
Thanks for upload this video ! Very nice!
My cylinder 6 started misfiring ( same engine) and pulled the plug out and it was covered with oil. Is the spark plug tube seal leaking??
Ponyboy Yes. Unfortunately you need to pull off the valve cover to replace that seal. Might as well get the valve cover set and just replace both sides as I show you in this video.
Thank you for the quick response!!! I figured that’d be the issue but wanted to make sure 100% thats what it is. Im uploading a video soon showing the plugs. Do check it out and confirm ua-cam.com/video/ZjgObHV3gDY/v-deo.html
The Gasket kit I'm getting is below. Please confirm that aswell www.thewrenchmonkey.ca/products/auto-parts/fel-pro/vs50690r/
Ponyboy by your video I am not convinced that you have bad tube seals. The coil actually looks pretty dry. The oil on the threads of the spark plug appears to be ok. As you see the tip of the plug appears to be in ok shape. The coil looks dry and just dirty. It would be wise to read the codes (if you have a CEL on) and then you can try and pull just those coil packs and inspect them for lots of oil on the outside of the coil pack boot as well as oil in the inside of the boot.
The valve cover set you have selected looks fine.
Ponyboy I would first clean off the threads of the plug with brake cleaner real good and then reinstall the plug and make sure you torque it down completely and make sure that it is completely seated. Then inspect the bottom of the coil boot (the spring inside should be dry) for excessive WET oil. If it is ok reinstall the coil pack. If the problem still persists on cylinder 6 then take that coil and swap it to the other side of the motor (ie the other head) and install it and see if the misfire follows that coil. If it does then you have a bad coilpack. If it doesn’t follow and stays on #6 then get back to
Me.
Thank you again. I will follow your steps and re-torque the plugs. The oil on the coil was minimal so it didn't show on the video properly. However, if you see the ends of boot between 0:30 - 0:35 you can see the ends of coil shiny. But there was oil on the coil 100%. Thanks again! I'll get back to you after performing your suggestions.
Should you unhook the battery
I would although it’s fine if you don’t.
I wonder If the tube seals where but on right you had them facing up but now won't slide in easy threw spark plug tubes I got them in by using plastic pry bar any ideas I looked at yours and put mine in just like you had them facing??? Help lol
Great video ! thanks ... BTW I would put something to cover the engine intake holes .
Same thought, the FSM directs them to be covered with tape. Fishing something out of there that got dropped in would be a pain and if working outdoors something is likely going to blow by and fall in there.
I started on the passenger side, eveything was moving along until I accidently stripped the threading on the banjo fitting hole on my GS350. Dont tighten down the perimeter bolts on the 17mm banjo fitting is in first...
Hey man, thanks for sharing this issue. I’m in the process of putting back the banjo bolt (Driverside) and I’m having a hell of a headache to tighten that banjo bolt back in place. Any advice?
@@marcomelo8576did you ever manage to fix it or did you end up buying a new valve cover?
@@michaelvd2467 I was able to fix it! Just had to be patient and tackle it at the right angle. It’s just a pain the a$$ cause there’s not enough space
@@marcomelo8576 great job man! I assume you own an IS? Noticed the very tight space around his banjo bolt on my IS. Won't be doing this job any time soon since my valve covers don't seem to leak anywhere but I'm mentally preparing for some big jobs in the future since my IS250 is at 200k miles now
do you recommend heating the engine before doing this? a couple Allen 5MM do not want to budge for me, I don't wanna trip then. Thank you!
I do not.
Just put a water pump in my IS350. took me about half a day, but I'm not going to lie. looking at this job. It does leave me a little intimidated.
Lol, it’s very time consuming as you can tell it got dark on me lol. But it is doable.
Not sure why Toyota would make things this difficult. They normally have pretty decent designs. But of course they can’t make everything easy.
I’m looking for the thread size of the oil check valve on the driver side valve cover
My isF has bubbles in the coolant tank but there’s no overheat u think it’s the valley plate?
Hey is there a certain way or torque spec I need to keep in mind when removing or putting back in the head gasket bolts?
You would need to look up head gasket torque specs online. However I did not do anything with the head gasket in this video.
on the two bolts that go to the fuel rail (behind the intake manifold) how did you get them off? I’m able to get one off but the other is kind of under part of the manifold. I can’t seem to get my tool onto it.
I believe I used either a small wrench or a 1/4” ratchet with a wobble extension. Sort of have to get creative lol.
Crows feet
You think its possible to replace the passenger side gasket without removing the intake manifold?
Probably but you would want to replace both valve cover gaskets at the same time.
Did you need to disconnect battery fr any lights that may pop up or is it ok to leave it connected?
I left mine connected
I have a doubt. The VVTi engine 2GRFSE is the same VVTi at engine 4GRFSE? The mine is damage and i want to know if compatible. Thank you
rất chi tiết sửa chữa và thay thế ,cảm ơn anh nhiều ,chúc anh có nhiều video bổ ích hiệu quả
Did you have to replace any o-rings when you removed the high pressure fuel pump pipe that connects underneath the intake plenum?
I didn’t
I keep getting p0455 and p0451 low evap i changed all the intake mainfold gaskets and changed the valve covers and spark plugs weirdly enough the evap hose connect to the purge valve wasn’t even connected when I started when I finished I felt like I was mixing up my breather tube and brake booster line it’s startes and cold starts smooth but when rpm goes under 1000 car won’t stay started
Very good video!
whenever you have to do this job. It's also a good time to change camshaft oil O- ring otherwise great video.
❤thank you very very much my friend this helped me a lot❤
That is a good work. I like it.
Thanks bro for sharing that.
What are the 2 hoses above the fuel pressure regulator? I have an IS250 and those 2 hoses are directly above the regulator and I may need to disconnect one of them.
Heater hoses
Can you tell me where the camshaft position sensor circuit A bank 1 is please
Bank 1 will be passenger side if you have the 3gr engine. Circuit A is Intake sensor. So if you are looking at the engine, in the front of the engine on the top of the valve cover on the passenger side cylinder head. There should be two sensors. One is for the exhaust cam, one is for the Intake cam. The sensor closest to the center of the engine will be the one.
Helping Hand Auto Repair thank you so much! Got code P0340 camshaft position censor bank 1 A circuit along with P0335 crankshaft sensor. Going to check wires/connection. If good going to replace camshaft sensor. Car will not turn on at all. 2008 Lexus GS 350 RWD
JustJay 0312 well you need to replace the crank sensor as well. I believe that is near the ac compressor on the driver side of the engine on the bottom or near the bottom of the engine. I don’t remember if you need to remove the ac compressor or not to get to it.
Helping Hand Auto Repair I was afraid of that, shouldn’t be too hard to get to.
Just curious, im replacing my fuel pressure sensor on my 07 gs350. Are there any bolts behind the plenum, or are they simply all over the top? And thanks, I'm gonna subscribe
Should just be the bolts on top. You would need to watch that portion of the video again tbh. This was a while ago and I don’t remember everything exactly.
@@HelpingHandAutoRepair yea thanks alot man. I've been literally studying this vid. Finishing up the repair this Saturday. I'll keep you posted
Do you have to remove manifold to change plugs and packs?
On the driver side of the motor yes.
@@HelpingHandAutoRepair Thanks
Did you have to shut off or remove the gas pump first?
I let started the car and pulled the fuel pump fuse and let it run out of gas to try and relieve fuel pressure.
Thanks for the reply! Shoot I have everything off already and didn’t depressurize the fuel pressure lol
@gerardonato7219 it’ll be ok
@@HelpingHandAutoRepair yo i just wanted to say thank you for posting this! Just finished the job and she’s running so smooth now, like new!
❤very detailed 👌 👍 thank you sir.
Do I have to take the manifold off if only need to do valve cover passenger side?
I don’t believe so. Not sure.
Just look at it and see if you have room.
Will this fix a car that has failed the combustion test on the coolant? I took it to Toyota and the basically said that I would need a new engine because I either have a crack in the block or a blown head gasket. If I open up my engine like this would I be able to tell which is which?
No this won’t help your problem. You need a head gasket job or a replacement engine
Did the job but now I’m leaking oil from the banjo bolt do I need new crush washers or why do you think it’s leaking?
Could need new washers. Or hopefully it’s not stripped.
Thanks for the quick response. I’m gonna get new washers tomorrow and hopefully that fixes my problem
yes this will solve the problem
In the middle of doing my 06 is350 right now. I unbolted everything on the driver's side valve cover but it's still stuck. Any advice on lifting it or loosening the gasket?
double and triple check there isn't a bolt still holding it down. Also if you followed the video completely, maybe you missed a bolt or bracket by chance.
Sometimes they are stuck pretty good and you can get a small flat head screw driver to persuade the valve cover to come up and off. You have to be careful you don't gouge the aluminum head sealing surface.
@@HelpingHandAutoRepair Thanks for the help! I missed the bolt between the coil packs.
What are the symptoms of a bad valve cover gasket?
Bojidar Lukanov oil leaks.

This is a useful video. Thanks for your time.
I have a question about the lexus gs300 3rd generation . I have the code P0420 which means catalytic converter bank 1 is broken or something like that and I supposed that the spark plugs are bad so I changed them but the one spark plug from 5th cylinder had a little bit oil on . I changed the air filter too. I cleaned the air mass sensor also the body assy throttle but the car runs bad and makes vibration . I made a diagnosis to the car and says that the oxygen sensor and catalytic converter are bad. Could you help me please?
Prior to fixing the spark plugs, air filter and cleaning the MAF was the car running fine?
No , that's why I make all this repairs.
Oh ok. Well I assume your car has a decent amount of miles on it? P0420 codes are indicative of a catalyst that is getting old. It could also by chance be a bad down stream O2 sensor on bank 1. This is not normally the case though as the catalyst is usually the culprit. If you have a scanner that can read live data, I can help you determine if the o2 sensor is bad.
As far as the oil on the spark plugs, you need to replace the valve cover gaskets to solve that. It is most likely running rough because it is misfiring due to the oil on the plugs.
The car has around 118.000 miles. I thought when I change the ignition coil of that spark plug which has oil on it maybe it will be ok if the problem will persists maybe I will check the catalytic converter with an endoscopic tool.
If there is oil on the coil then you need to replace the valve cover gaskets as shown in this video. Otherwise you will continue to have a poor running car because the spark will be arcing off into the pool of oil instead of going to the spark plug. This car must have been driven like this for a little while because now you have the 420 code which is being made worse by driving the car with a misfire.
Fix the misfire first. The catalyst is getting ruined or may already be ruined.
Torque specs and sequence???
I'm stuck at the banjo bolts now. Mine are leaking😩I'll have to order new ones
What did you do to tighten the driver side banjo bolt back in place. I was able to get it in but that 🤬 is not tighten. Any advice would help. Thanks!
Stuck on my banjo bolts super tight . Starting to strip. On the GS 17 mm 😮😔
Same thing happened to me, but I was able to get driverside loosed with a 17mm 12 point closed wrench. For the passenger side I used a 17mm socket with with a 1/2 extendable ratchet to loosen it up.
Any tips for the gs 350 model? The working room behind the intake manifold and throttle body are extremely limited. The intake manifold is a slightly different design. The throttle body and intake manifold are closer to the rear
What year?
2008. I got the intake manifold off and started loosening the driver's side cover but I'm worried about the passenger side with that fuel pump or whatever that thing is. Those two thicker coolant lines that are behind your fuel pump are directly above the fuel pump in my model, going to try and wriggle it out from underneath them today
Good luck. Your motor is still a GR motor but just slightly different in a few ways. Overall mostly the same.
@@HelpingHandAutoRepair would you recommend taking the fuel pressure regulator's top part off so I can get some clearance to get it off of the cover
If you need to.
Great work. I’ll hire a mechanic to do mine. 😂😂.
Anyone knows what’s the torque specs for the bolts on the aluminum manifold and the plastic manifold? Can anyone answer that?
Stripped the Alan head rachet screw in that middle part can't get it off 😢
Would need to get a screw extractor now. Not much room in there, good luck.
You should get more camera install on different angle's
Couldn't saw when you removing circuits grip😥😥😥😥😥
Hey man great video. I'm contemplating doing this on my 2006 RWD IS250 which I think has seeping oil from both side cam covers. It's been like that for a good few years. Does it effect anything if I was just to leave it seeping? And clean it once in a while?
John Roberts No it doesn’t other than smelling oil burning on the stock exhaust manifolds. This smell can enter the cabin while using the fan inside if you have outside air selected. It’s more annoying then anything really.
Also you will need to keep an eye on your oil level. As it will gradually lower the oil level.
@@HelpingHandAutoRepair Thank you.
This video is a revelation to what’s wrong with my is250. I thought it was jammed brakes. But no, it’s burning oil.
Same problem here john..did you fix it ..I have same is250 rwd 145k km and it's leaking from multiple places on both side of valve cover ..should I fix it now because the car give that smell often when I push it past 120kmh
You definitely should try and have it replaced or do it yourself. The smell is just annoying. Plus you are losing oil over time and we all know what happens to engines that have no oil.
Oh man! Im a weekend warrior, and i dont think i should be doing this myself, lol.
It’s definitely not for the faint of heart
Any idea how long they should last after replacement?
The same as those did
