Porsche 944 Balance shaft cover installation tutorial
HTML-код
- Опубликовано: 15 сен 2024
- In this video I show you how to remove and reinstall the balance shaft covers on a Porsche 944 engine. There were several changes made to the covers over the years and I go over some of these. Installation for the most part is the same for all the covers but you may need to refer to the manual for specific engine. Later on I'll try to make a video installing all the different covers and showing how to torque them down in the correct sequence. Thanks for watching!

my new favorite channel ! Thanx a million for all the advice
Thanks for posting this. I gotta say that's 10x the amount of sealant that's needed. All that's needed is a thin coat that just tints the surface orange. An art brush works fine.
Thanks, yeah Porsche applies it like that and then spreads it around with a foam roller, but still rather thick. Whatever is left is soaked up on the the roller and is unusable, so since its going in the trash either way, I'd rather just make sure I got enough on there. What ever tiny bit oozes out on the inside will just come out with the next oil change.
It looks like I get to do this soon, even though I wasn't planning on it. I was just cleaning up the block a bit with wipes after installing the oil cooler and felt something loose at the back of the balance shaft cover on the passenger side. It turns out the aluminum disc piece where the o-ring is is as loose as a goose! It doesn't look like it had been leaking terribly, but I may as well since I have the exhaust manifolds and front suspension/cross member off. It's as good a time as any.
Thanks for the video 👍
Another great video in detail this really helps when doing your own car and watching this for reference. Keep up the good work thanks again.
Will do! Thanks!
Thanks for another great video!
Just curious would it be possible to seal balance shaft covers with hight temp rtv ? Or does it have to be loctite.
It needs be Lotite 574 flange sealant or the Permatex version. The Permatex version is okay and is available locally at most auto parts stores but the loctite is much better to use. Flange sealant is a must since it is anaerobic, so it will only cure between the mating surfaces. Any excess that gets squeezed out inside the engine will remain a liquid that dilutes into the oil and will come out in during the next oil change. RTV will also squeeze out inside the engine and cure into rubbery strands. Those cured RTV strands will then tear off where it will get into the oil system clogging passages, causing damage. I've seen these strands get mashed up into muck that starve bearing surfaces of oil as its pushed through the engine over and over. Many times the only way to get it out of the engine is to do a full rebuild. I hope that helps!
You’re the Porsche 944 god. Thanks again. I have a question. I just found the lower balance shaft rear seal o-ring leaking on my 87 NA. It looks like I can pull the header, pull the motor mount bracket, and R&R the lower balance shaft cover with the motor in the car. Is this the easiest method (the car needs motor mounts so kills two birds) I’m ashamed to say that I cleaned it and slathered RTV all over it today to try and buy myself time but my car was just down for two months while I did LOTS of things to it and I just really want to enjoy it for a little while before I tear into it again
Yup that’s exactly how we do it here! We drop the cross-member and then pull the cover. Also doesn’t hurt to use some sealant on the new seal since they’ll just shrink and you’ll have to go back in there again. Good luck!
What are the torque specs for the balance shaft end supports? No one ever mentions it and I can’t find it anywhere.
Are you talking about the caps? I think they’re 13 ft/lbs and is just listed as the spec for all M8 bolts. I hope that helps!
@@edredas Thanks. That is what I was looking for.
Great channel. I own a 951with an overhaul coming soon. What's your opinion on balance shaft delete? Thanks
Thanks! Balance-shaft deletes are a hotly contested debate in the 944 community. Most people on forums incorrectly think they are there to prevent the engine from shaking apart, but this has become so ingrained that it's hard to convince people otherwise. They are there to make the engine quieter and smoother for the occupants. In other words, they help reduce the vibration to about a straight-six level and so it makes the driver feel like they have a more expensive engine under the hood. Keep in mind a Inline-five engine is smoother than a straight-six at higher rpm and a cross-plane V8 has far less vibration than both. That said, most larger inline four engines never had them and they were fine, with many still on the road. They just aren't known for being very refined. I remember back when I was growing up that many people were boring out 2.5 liter L-4 GM Iron Dukes to 3.0 Liters and making around 700-ish hp at high rpm. Those engines were bullet proof and never had balance-shafts from the factory. I owned many of these types of engines and also have a 944 with balance-shaft delete. I've never had any issues, but it's up to you since I won't get into the middle of such debates. The main reason is, most of them are not aware that it is rare for a large inline-four to have balance-shafts so you can't take those people seriously. I hope that helps!
Is this feasible with the engine in the car on early n/a ? Do you have to remove the intake for the upper balance shaft
Yes, it is possible to re-seal the upper balance-shaft cover with the engine in and just the intake removed. The lower balance-shaft can also be re-sealed with the engine in but it is more complicated and requires the engine being supported while the lower mount bracket is removed. I hope that helps!
Is it possible to leave the nose housing on (just remove bolts) while resealing the main housing and replacing the oring? Also I bought an oring that was listed for 83-87 model years. Do I have to get a different oring? The engine is a 87
I have had to reseal one on a car that was leaking. I left the belt on and everything and didn't have any issue. I figured having the housing off my lift the shaft up back there but it didn't, but I don't really advise doing it that way if you can help it. That said, the rear orange O-ring seals are completely different between the 1983 and 87 engines. You'll know if you have the correct one because the early car O-ring will be way too large. I hope that helps!
@@edredas thanks, I reordered the right orings.
@edredas I went to do the seal for the lower balance shaft cover and I went to remove the engine mount bracket and the bolt on the lower left of the mount bracket is hitting the exhaust manifold. Am I doing something incorrectly? I really dont want to take the manifold off in fear that a stud may break. Any thoughts?
@@Gearsandgrease The lower cover is such a nightmare to do in the car. I believe removing the header nuts from the head and pulling it back is the only way to do it unfortunately, so just take your time. I hope that helps!
@@edredas it absolutely is. Thanks for all your help and videos, I have seen just about all of your 944 videos and you have made me very comfortable with wrenching on the 944. I always look forward to see what you're up to next! Thanks!
I watched a few balance shaft cover videos and there’s never mention of that thin plastic washer at end of shaft
That thin clear plastic washer sits directly behind the sprocket, between it and the lip on the shaft. I hope that helps!
edredas thanks
