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.

Thank you for posting these. So helpful. Fantastic channel ❤🤘😎

Great video! Thank you!

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

First lol. Looking forward to the rest of the series!

Very interesting failure mechanism (low oil pressure due to cheap oil filter), I’ve never heard of that one before.

Great to learn ...

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.

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

The piston that the relief spring activates can stick and cause oil pressure problems and should also be checked

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.

Is that spring attached to the oil pressure regulator spool? It looked like it was pointing towards the pump outlet.

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?

What’s you thoughts on the k&n oil filters that’s all I’ve used on my 997

@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!

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.

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?

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

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....

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!!!

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.

A bit of cardboard and put the bolts through in the patern they go in . Yellow oil is water????

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.

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.

What do you consider low?

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.

Is this an issue on GT3s??

Factory spec turkey gravy.

"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...😬

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 kzread.info/dash/bejne/emmDxqmdk9S_daQ.html

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.

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?

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.

As long as it rises and stays above 4psi during driving (and its warmed through and bedding in oil) I'd say its fine.

@EhWassAmattaU

Ай бұрын

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.

If the spring is the same, it has part number starting 996, isn't it ? Or else it has e.g. 987

I do the same with mine but I also keep it below 3000 rpm until oil temp is up…

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.

My 996.2 has 105,000 miles and the only non wear problem I’ve had is the ignition switch broke and was replaced. It’s my daily driver for 20+ years. I follow the factory maintenance and that’s about it. I did add a K&N air induction system and that added some better throttle response and as a side effect made it sound a lot nicer.
