It’s incredible how tight those head bolts are clamping down on the gasket, and yet these are still prone to blown head gaskets.
I saw one of your other videos ..very professional in explaining what tools are required and "keeping a STEADY CAMERA"
+option man glad you enjoyed 👍
out of like 30 videos I've seen yours was qui k and the most helpful thanks!!!
+Race Religion glad to help. 👍
really informative and high quality video. thanks a lot.
+16mmDJ glad you enjoyed it
Thank you for all of your highly informative videos, SirSubaru. Many of your videos have helped me work on both my 09 WRX and turd 99 30th L Wagon.
I suspect that my 2.2 in my wagon has a an exhaust valve that isn't fully closing. I need to do more diagnosing, but if that is the case, would you recommend me trying to replace said valve? Or should I just grab another cylinder head from the wrecker and throw it on?
Again, thank you for all the information you make available for novices like myself!
Cylinder leakage test to confirm. Then go from there. Probably cheaper to have the head rebuilt than getting a used one and having it machined.
@@MrSubaru1387 Thanks man, I will do just that.
Hell ya right to the point and no talking about shit that doesn’t have anything to do with the video keep it up bud 👌
Great work Sir, Greetings from New Zealand
+IGNATAM AMUOH glad you enjoyed the video. 👍
Your videos are freaking great!
+Walter Elkin thank you, glad you enjoyed it.
nice video. planning to fix my ej20. thank you sir.
+Bochok Galante glad you enjoyed the video
+Bizza12345 the EJ20 and EJ25 are pretty much the same procedure.
was it similar for the ej20?
MrSubaru1387 thanks :) my ej20 turbo leaking oil from the head pretty bad so ill be using your guide amongst others. thanks again for the quick reply
+Bizza12345 you're welcome!
Super helpful! Thanks a bunch!
You're welcome. 👍🏻
Your videos are top notch! Keep it up!
+Mike Munoz thank you. Glad you enjoy them.
I really wanna get a Subaru, but the head gasket-S are the main concern. It's gonna happen, but you don't know when. And since i'd be buying a used one, it could be anywhere from immediately to 10 years from now. And the fact that you have to pull out the engine to do it makes it very costly. Definitely something i'll never be able to do myself.
You can replace them in car, just easier engine out. They usually fail between 120-150k miles. Only the 2.5 has the issue. The H6 and 2.2 are fine.
I do not know why the cam sprocket bolts are not budging at all I’m using high impact gun like the video and nothing. Some slipped possibly bent valves right? Anyone know what’s going on with bolts? Any pointers
Someone might have been in engine before and put loctite on the bolts.
great video! just one question, is it necessary to send heads out? or can i just clean them up and reassemble?
+shootme17656 well that all depends on how long you want the repair to last. It's better to send it to the machine shop and know it's 100%. Why chance it with all the time and money invested in the repair?
good point, thank you
Watching that back I wish I would have caught that you need to loosen the cam shaft retainer bolts in a series and now I have stripped second set in on my ek25d! Was trying to attempt this in the car and was a breeze til that... any tips to try and remove them?
I am gonna try and retorque them and remove like you did and see if they aren't seized from overheating
Do u have to remove all pulley for heads? I replaced all mine and only want heads off? Thanks
overpaid for an unknown '06 forester x 140k, the engine and trans still seem sound. wet oil grime above the pan but looks like the flipper just gave it a bath. no drips after a week and 100 miles. it does need new belts and fluid swaps that are on my fair weather calendar. should i plan to, suck it up, pull a happy engine, and do the valve covers and head gaskets as preventative or just do the obvious?
No, I'd just keep an eye on the oil level and the underside of the engine for now.
Is there a reason why you didnt use the electric gun on the heads and cams?
Great video!
+Stan Kaplan thanks. Glad you enjoyed it.
Awesome video!
+MotoZixxer glad you enjoyed it.
+zcamaross09 You should do an engine removal video sometime if you ever get the chance.
+MotoZixxer yes, I do. Meant to film pulling this engine and pulling the engine for the clutch video, but was in too big a rush to be able to.
And will a 1998Forester rear hub assy fit a 198 outback
nice work
+Omaid Amiri thank you
Did you determine blown head gasket through compression test? I can barely install new spark plugs in the 2.5. Very tight. Would seem awkward to attempt compression test.
Silly question. Just found your video on doing compression test on dohc ej2.5. I’ll give it a go!
Cylinder leakage test.
@@MrSubaru1387 thanks for the quick tesponse
@@MrSubaru1387 I’ll see if I can find a place to rent the cylinder leak tester. Every auto part rents compression testers but if that’s not what you recommend. I will check to see availability on leak tester.
Apologies for the potentially silly question, but I've only dealt with the SOHC engines so far: What do you do with the valve shims when the heads go to the machine shop (i.e., can you leave them in, or do they require removing)? Also, would you do valve clearance check before removing the heads to see if any of the shims needed replacement in the process? TIA.
I send the whole assembled head out to my guy. He checks clearances and adjusts/replaces the shims as needed to put the heads back in spec.
@@MrSubaru1387 Cool, thanks! I'll make sure my favourite machine shop does the same then. ;-)
Hi Mr. Subaru, after much wait and search, I finally found and bought my very first Subi! An 01 Forester with only 114K miles! The head gaskets are bad(bubbling in the coolant tank). Since its engine is the later H4 EJ251, Can I still use this guide to take the engine apart? I think it’s pretty much the same one right? Just wanted to confirm before I start. Btw, I read on a post that supposedly the EJ25 turbo gaskets are better/stronger? To rebuild the heads, would you recommend any aftermarket gaskets or sticking with Subaru OEM ones? Thanks
It is similar, but there are differences in the valve train. Stick with Subaru OE head gaskets, just make sure they give you the new updated MLS head gaskets.
Congrats on the new-to-you Forester.
MrSubaru1387 Ok, will do 👍🏻
MrSubaru1387 Thanks
You're welcome 👍🏻
I have a 05 impreza rs how hard is it to replace the head gaskets in frame? Or do you have to pull the engine?
Great video
It can be done with engine in car, but it's so much easier out of car. Especially when you go to torque the head bolts.
Nice video!
Have you another video like this but on a ej255 wrx turbo engine? I need to remove the cylinder head, but I don't found any "explain video".
+Guilherme koetz I don't have a video for the EJ255 or EJ257, but the procedure is very similar.
Ok. I will try... thanks!
A used Subaru pre-2012 with no Head gasket symptoms
Is it wise to replace the gasket as a preemptive measure? or wait for failure?
How many miles on the engine? Is the engine out of the car, or your just talking about the car? If the engine is already out, I'd probably replace it as a precaution. If not, probably wait until it goes. Best I've seen them make it to (so far) is 330,000km, so the stock gasket *can* go a ways (but rarely).
I have an '03 H6 with 220k miles that has exhaust bubbling into my coolant resevoir so am weighing what do do about that obviously blown head gasket. Would you recommend doing dealing with that in car or pulling the engine? I have another car I can drive in the meantime so it's not a big rush, just want to choose the most effective way to do it.
You have to remove the engine to do EZ30D head gaskets.
how do i remove the cam pulley without it moving.......i do not have an impact driver ...and when i put force into it moves..im afraid of damaging something.
You'll need an impact, the special cam pulley holding tool, or you can rig up a strap wrench with an old timing belt.
Hi, what engine stand are you using in this video? Do you have any recommendations for bolt-in, reconditioned/rebuilt heads, or is the consensus generally better to send out the heads from the original vehicle for machining. Trying to reduce time of repair.
+Scott LaLiberte I use a Torin brand stand from Northern Tool. Had it for years. Depends on speed really. I use a local machine shop, but swapping your heads as a core for a reman set is just as good.
Thanks!
Mr Subaru ,you mentioned that a 2005 Forester head would fit on a 2002 out back ej25.what different head would fit on my 1998 ej25 out back
98 is an EJ25D DOHC. You'll need another EJ25D head. The EJ205 and EJ257 will bolt on, but the compression ration will be off due to them being turbo heads.
@@MrSubaru1387 thank you sir
2011 subaru impreza 2.5....need to do a clutch on it. easier to pull the engine or trans to do it? thanks dude
+jacob gerstenfeld engine. I always pull the engine for a clutch job. Easier to go back together that way as well. If you pull the trans you have the shifter and axles to worry with, plus the engine will "fall" forward and needs to be supported without the transmission in place.
How do you keep all of the nuts organized?
Where did you find the torque specs for all of the bolts?
+Jared Nadeau I usually lay parts and their corresponding fasteners together on the bench. Torque specs are from the Subaru factory service manuals.
Out of curiosity, did the heads warp when you removed the gaskets? What other reason would you need to send it off to replace the gaskets? Or can you basically assume that if the gaskets are blown the head is warped, period?
I'm about to have to replace the head gaskets on my ej22 and am on the fence about just getting a build kit and assembling one, myself.
It is always recommended to check the head and block for straightness when changing the head gasket. It does not warp from simply removing it. It warps from heat and time after a failure. There are specs in the service manual for the straightness. You measure with a straightedge and feller gauges. The best advice is to send them heads to the machine shop. They clean and de-carbon the combustion chambers. Resurface the head to 100% flat so you need not worry about the new gasket sealing. They pressure test the valves, check the heads for cracks, check the valve guides, and adjust the valves to spec by changing the lifter pucks.
MrSubaru1387 That was actually a lot of useful information. Thank you.
Roughly, what would be the cost of sending the head off and having all of that done?
+Shanon Sizemore my machine shop charged $500 for the pair. That was to hot tank, pressure test, check for cracks, lapped the valves, replaced valve guides, and adjust all lifter shims.
Hey Mr.Subaru 13:15 When putting everything back together, do the cams have to be in the exact same spot/location? Sorry I'm not mechanically inclined.
Hakasauars yes. The intake and exhaust cams are different, they have to go back where they were.
Does the positioning of the cams matter?
On disassembling and assembling, the cams will be in neutral position, no tension on valves.
Thank you sir
You're welcome.
Okay thanks, and it’s normal right? lefty loosey???
Correct
MrSubaru1387 thank you very much, great video by the way, I’m sure someone changed timing belt before and put Loctite on install
great video, any chance you'll be working on a 205?
+Aegon Targ not in the foreseeable future, but, you never know.
also why remove head bolts from the outside to inside instead of just taking them off at random
+option man because that's the procedure in the shop manual. Haha. Seriously though it's because the center bolts are torqued last and to a higher clamping load. Helps prevent warping and stress to the head.
what kind of head gaskets you are going to put it on?
some people said the fel-pro gasket are the best
+thesniperofcs OEM Subaru MLS. The only gaskets I use.
+zcamaross09 Thank you for your reply 😊
Mr subaru... I have a 07 legacy 121.000 miles head gaskets still good.. do you think they will last to 200.000 miles or are they going to fail Thanks..
+jpntjp1 being a 2007, it should have an EJ253. These aren't known for head gasket failures as sl commonly as the EJ25D. If/when this gasket fails, it normal does so externally. It will leak oil between the head and block rather than leak coolant into the combustion camber.
MrSubaru1387 Thanks ... keep up the good work ..love your videos learning a lot..
+jpntjp1 you're welcome. 👍
Do you replace the head bolts when doing the head gaskets?
+mat win as a rule, yes. But, you can get away with reusing. Uses two separate installation procedures.
Just did this same motor day before yesterday. What is the part number for those pliers? They would be a big help.
+BAKWOODS KID which pliers? Can you tell me the time on the video?
MrSubaru1387 around 5:08 removing the PCV hose?
+BAKWOODS KID Snap-on 196NCF
MrSubaru1387 awesome thanks! I've only just started as an apprentice. You're channel has been very helpful.
+BAKWOODS KID awesome! Glad to help!
I hope your wristwatch has a screen protector film. ;)
+Andrew Wrobel it doesn't..
what did you use to get the block clean before putting the heads back on?? whats the best way to clean them up?? Thanks
I used a brass brush, lots of rags, and brake parts cleaner. Had a large drip pan underneath to keep from making a huge mess.
Great man thank you so much was wondering how u did... re building my motor now on my wrx wanted to have it ready for when the heads come back. one more question i see you used assembly oil when putting the cams back in is it ok to use motor oil??
+Blake Roderick I'd strongly recommend using assembly lube. It's relatively cheap from most parts stores. It's stickier than oil and protects everything better on the first start. After the rebuild it takes a while for oil to be pumped out everywhere it needs to be, the assembly lube protects engine parts better/longer than oil until pressure builds up.
Ok thanks I was just wondering cause went to the part store to look for it and couldn't find it but will try couple other places and see if they have it!! Thank you for all your help man!! Love the videos as well they helped me a lot when i wasn't sure on something!!
+Blake Roderick always see it at Advance Auto Parts. Where I usually shop. Usually grouped with the gasket maker/sealer/RTV, etc.
Do you always resurface a head when doing gaskets??
Yes. Always.
Thank you im going to be doing the head gaskets on a 1997 lgt 2.5
Great videos btw.
Hey @MrSubaru1387, I'm trying to lift my EJ25D 98 Legacy Outback. Is it possible to lift it with the intake manifold still attached? I see that most of your videos, you have the intake manifold still attached. What is you trick? Thanks!!!
+Nasir Younus what do you mean by lift? You're lifting the suspension? Or do you mean lifting the engine out of the bay?
MrSubaru1387 sorry shouldve been more specific. Lift the engine out of the engine bay. Thanks!
+Nasir Younus yes, you can remove the engine with the intake in place.
MrSubaru1387 where did you hook up your chain to in order to pull it out? AC bracket and the hook that is on top of the engine harness connectors in the back?
Yes, be careful though as the loop at the connectors in the rear isn't super strong and can bend and deform.
where did you learn how to do this?
+Fronita Wan I grew up on a farm with an ASE Master Tech father. Been fixing things all my life. I graduated with honors in automotive technologies then ran my own auto repair shop for several year. I've been working on Subarus for the last 8 years or so.
MrSubaru1387 nice👍 helpful video
over heat ?
Yes. Blown head gasket.
I wish there were talking involved instead of text on screen
+Chris Fritzgerald trust me, text is better than listening to my voice. Haha
Do you know how often I thumbs down videos I don't even watch because the UA-cam algorithm won't stop recommending a video in which I am just not interested in the subject?
