I've only used Mann since I got my 996. I change oil / replace filter every 3K. Anyway, love the channel. Glad I found it, because I have plans to do quite a bit of my 996 work going forward.
@Johnny Bravo I think he mentioned in one of the other videos that he was 98% sure it was either the oil cooler, or the AOS, or a combination of both. Though I need to give those another go cause I have the same mayonnaise in coolant!
My 997 3.8 engine is always around 4 1/2 to almost 5 on oil pressure until it warms up and then rarely drops below 3 1/2 and I was worried it was so high. 😅 I guess I am blessed!!!
@@anonymoussee8960 I had a friend who spent years looking for a good used one.. I was in Oregon ( before the Californians invaded) so the offerings were not plenty but not bad.. I looked at so many cars with him that were decent drivers, just like beat up Chevies and Buicks, which is what they were to the previous owners... NOT what he wanted, he finally found a garage queen ( Guards red/black leather).....
Coolant in the oil, look for a cracked head. If the 996 and 997.1 with M96 and M97 engines are ever tracked adding an $800 deep sump extension which adds 2 ltrs of additional oil is an absolute MUST if you want to keep your engine from oil starvation.
Great video really helps those of us with 996's in the garage. When your schedule permits, would you mind posting the torque specs for the oil pump cover plate and the spring bolt? Thanks
Based on the fact that some of these paper filters "twist" when installed and cause oil pressure problems, I wonder if this is another argument to install an L&N Engineering filter adapter that will accept a screw-on metal filter....
Other than replacing the spring, what did you do in this video that would improve the oil pressure or flow? Or was the spring the primary issue you wanted to address?
I always used the Bosch filter because its really an industrial use filter and has the two end caps in plastic with o-rings and the plastic inner frame. Thought process is that it feels more robust compared to something like the Mann filter, but I wonder if it is any better at all.
"First things first" ??? The FIRST thing I noticed (when you broke the seal) was the creamy oil! "Well, there's your problem" (as the MythBusters used to say) "pretty sure" that is NOT normal... water is A LOT thinner than 40w oil, and will give you low oil pressure. IMO...😬
How is changing the spring going to increase idle oil pressure? At idle the pressure is 1 to 1.5 bar or ~20psi and the bypass opens at over ~75psi. The spring/bypass doesn't know it's idling, it just opens when psi is over ~75, at high engine RPM, so it doesn't blow out the filter.
HI, I understand the same. But then, if a stiffer spring helps with oil pressure at idle, does that mean that the valve opens always, letting bleed some of the pressure? Is this the way it works?. Thanks!
If the oil filter is a major problem, and causing low oil pressure at idle, as you say, it would have been resolved a long time ago. Everybody does not have the problem you suggested. I think you have a few other problems. We have never seen it on our 996.
Unfortunately.. believe it or not.. there’s people that don’t know one bit, about their cars.. other than the steering wheel turns their car.. those are the ones that will still take it to those places..
Hey, I just changed out the oil pump on a 997.1 b/c the housing had a micro crack and was sweating coolant. Now that I have the new one on, is there a step to prime the new pump before startup? Or is it actually direct fed from the sump because it's down so low, in other words when you refill the oil, the level in the sump actually fills the oil pump housing too?
Hey!... i saw you toss an EXTRA spacer washer in there BEfore the spring went in.... Higher OIL pressures!? You oil pressure Ninja!! cant fool me with that Dr Mgillicudies magic.. Oh yeah.. my old lady(cinnamon Jr.) not from the jiggly room.. says hi. she saw you today at walmart she bought some sequence g-strngs.
If these engines are notorious for low oil pressure at idle, and this engine has been around is various displacements for decades, please tell us from which year forward did Porsche finally addressed and fixed this issue. And if they did fix it, can you share with us what changes did they make to the engine to fix it? Also, please share with us if to your knowledge, they have never fixed this issue.
Strange... my 89 VW had low oil pressure its entire life. VAG just liked it that way? My fix was (at least) 10w40 oil plus the Mann filter. OR 20w50 syn oil, even if winter.
Have you taken off the oil pump housing? I need to remove it to gain access to two bolts that hold in the timing chain guides, and I am having a bit of trouble getting that housing off and wondering does it in any way support the IMS somehow, if you can assist please.
Hi I have a 2006 997 Gen1 I replaced the water pump and thermostat complete with housing and replaced the coolant and replaced it with new coolant since I’ve done that I’m having a problem with The temperature gauge every time I go on a long journey and get above 50 mile an hour it drops out stops working I’ve replaced the sensor with a genuine Porsche one and made sure all the air was removed from the system but I’m still having this problem I wonder if you’ve got any advice that you can give me many thanks Ron from London England
Replace the oil pressure valve with the updated version from the 997 for better low rpm oil pressure! And the spring looks the same but it is a different stiffness so update that as well. I did a video on it here ua-cam.com/video/H5OdGdcqYEA/v-deo.html
@@NathansPorscheWorkshop the updated piston with the bevel on the edge is the big update. Did you get one? It’s only a few bucks and the pressure increase is well documented.
hi nathan the link i sent of the guy who had coolent driping from one of the oil pump bolts there is a water way right at the bottom just to the right of the pipe and just above it is the oil pick up to the pump in if that gasket has gone it could take water in there, while your at that stage and its nice and easy to work on might be worth a quick look
@@NathansPorscheWorkshop your better off doing that like you said some one has already been in there and you dont know to what extent ... i bought a 2003 boxster the guy said it just stoped so i got a friend to put a new battery and starter on it ... any way off i went when i pulled it apart 1 piston was shatered the liner was smashed out the piston next to it was partly smashed the valves bent half the piston stuck in the head ... lol... and it just stopped i think he forgot to mention the crunch crunch bang bang and the wheels locking up so they never tell you the full story
You better split the case. A few months after you put this back together? It will start losing coolant *again. But you wont find it. There is a O-ring seal at the top of the block for a water passage.. guess what the oil in the water does to this seal? It turns it to JELLY. The engine will DRIP water from the passage into the block. Hot oil will evap the coolant at a slow rate so you wont find it in the oil... but every few weeks you will be adding coolant. Do yourself (and the owner of the car) a favor and split the case and replace the upper water passage seal in the block. 20yrs of building and racing these engines.
Hi thanks for the great video. What oil pressure reading at idle (fully warm) would you say is getting to the point where the pressure is too low? My 997 shows 2-2.5 bar. Also, is it possible to just change that spring on the car without removing the bumper and crash bar? Another question, if the filter has twisted, can you tell when it's removed, or will it just spring back straight when you take it out? Thanks again.
2 bar is 29psi (not knowing much about the 3.4/3.6 yet), my 1974 2.7 has 10psi at idle and that is normal. I think 10 psi/1000 rpm is the norm for the air cooled engines. I guess it depends on where the oil pressure sensor is measuring what the bearings are seeing (obviously what the the bearings gets is MORE important than what the gauge gets...) P.S. the aircooled 911 engines never had "bore scoring". I wonder why? (sarc) and it is NOT the cooling.
How's its going BoSs. I'm just curious about your opinion on two cars. I'm asking you because I believe you have the best answer. Between a 2021 BMW M5C and a 2021 Porsche 911 gt3, which one do you think is more reliable please?
Nathan, i need help. I'm buying a 996 c4 3.4 and I'm looking for options. Just went to test drive one and after the test, oil pressure was 0,9bar..that is not good isn't it? Then...i didn't feel much power, owner told me he repaired the oil/water exchanger and there was no IMS slot because it is a 997 engine...no clue. Saw the engine heads and i read VarioCam F1, and M96/04 so it's a stock engine. With my diagnostic tool it read 0 degrees deviation on bank 1 and 1070-1059 degrees on bank 2 on warm engine. I'm afraid that engine is already gone...fortunately no trace of bore scoring. Oh...oil was a 5w50 btw. What would you suggest? To run away right?

So how did the water get into the oil, did I miss that in your videos

The piston that the relief spring activates can stick and cause oil pressure problems and should also be checked
First lol. Looking forward to the rest of the series!

This 996 is also that way
Imagine finally owning a Porsche and taking it a quick lube shop for oil changes. Unreal

The new model oil pressure relief valve has a beveled edge on it. Works much better. Solved any issues. As well as the new spring is slightly longer.
Very interesting failure mechanism (low oil pressure due to cheap oil filter), I’ve never heard of that one before.

A bit of cardboard and put the bolts through in the patern they go in . Yellow oil is water????
Other than replacing the spring, what did you do in this video that would improve the oil pressure or flow? Or was the spring the primary issue you wanted to address?
Is anything right with these engines?
Remember this is the first water cooled engine Porsche did except the 924 944 and 928 , this was the first flat 6 at least
I always used the Bosch filter because its really an industrial use filter and has the two end caps in plastic with o-rings and the plastic inner frame. Thought process is that it feels more robust compared to something like the Mann filter, but I wonder if it is any better at all.
I would only use man filters

Any way to get that oil pump off without dropping the entire engine out of the car? Asking for a friend…

We change the spring on these no matter what since the original spring can break or become weak

Where do you find torque specs for the 987.1 and what pressure do you like to see at startup idle?

Never take a car to a quick oil change place. They will destroy your engine

Did I miss how the coolant and oil are mixing?
Aaaaaahhhhh, yeah. Where was the leak?

Pack the pump with vasoline for quick priming Please

Is that spring attached to the oil pressure regulator spool? It looked like it was pointing towards the pump outlet.
What’s you thoughts on the k&n oil filters that’s all I’ve used on my 997

OEM filters are MHALE !
What do you consider low?
is this the car that you thought needed a new engine? Would u also change the Ims bearing as well since you have the engine apart
IMS is ordered
The earlier cars such as this had a double row ims bearing which rarely gave trouble.
@@petergordon4525 That is true however while it is apart it is better to be safe and avoid a grenade in the engine.

How much does that 987 spring raises the oil pressure at idle when hot? Maybe also a couple of washers could do that job to raise it a little bit
It doesn't increase any at idle. The bypass spring doesn't "bypass" until ~75 psi.
@@DSC800 you're right. I didn't use the logical sense here. Thanks man
Is this an issue on GT3s??
Porsche says not to let it sit and warm up and idle, it’s start and drive off.
I do the same with mine but I also keep it below 3000 rpm until oil temp is up…
What is the correct oil pressure at idle for a 996.2?
@@johnnybravo6913 I'm just asking man, are you always in a bad mood??
If the spring is the same, it has part number starting 996, isn't it ? Or else it has e.g. 987
