oil leakage from valve cover

BartdeBruijn · 02-28-2021, 05:52 AM

Hi,

a lot has been writen on this topic....
I only have a question what sealant could help fixing the issue shown in the picture.

I suspect that this cut shown in the picture(even if it is not over the full surface) causes my annoying oil dripping. Or it sneaks through the thread and nut.
Does anyone has experience supporting the normal gasket with 574 or CurilT....
Initially for the cut but maybe also on the thread?

Thanks for reading and hopefully someone can give me a direction here!

You can fix that with some careful JB weld application.

I had an issue with my engine sump filing with oil and leaking bad somewhere around #1 during storage. The Rennsport oil valve cured this issue, but I never figured out where the oil was coming from, it doesn't leak a drop now.

Bart,

You might also try the red silicone gaskets, The torque onthe valve cover nuts is very low, IIRC approx 5 ft-lb. They are thick and soft and may solve your leaking issues. I believe Pelican sells them.

Best of luck,

Easy Peasy fix with 3 bond/RTV. Just put a dab in the area before putting the gasket and valve cover back on.
Remember to put it on when you next adjust the valves, too.

Thanks for all replies!

I am currently waiting for some parts and will let you know which worked best.

@Mark: This The Rennsport oil valve is something that could come in handy too. I have the same that after a week all oil migrates from oil tank through oil pump into case and then it starts to drip. I am, as some other, bit worried about a valve in your oil supply. Even that I know if valve fails it opens/does not restrict......

Last winter under my car it was a hasmat super fund site and starting the car resulted in a fire department visit.
Yeah I'm exaggerating a tad, but not a drop of oil is on the floor this winter.

I was also worried about it, but it's a simple well made part.

Used the silicon bead gaskets to start with and awaked my car from the winter sleep she was in
Warmed her up and no leaks so far ;-)
So far 1-0 silicon bead gasket vs oil leak!

Hi,

Small update on the valve cover leakage.
I tried first the silicon bead ones. Still leaking. I bought long time back the orange full silicone ones from our host. Used them then with no success and put them away.
After removing the turbo valve cover I could measure some none flatness of 0.05 - 0.1 mm. So, together with the small cut in the cam housing (see picture) and the non flatness I decided to use these full silicone ones. Using the low torque rates and untill now no dripping ;-)

Will keep you further updated!
Regards,
Bart

Hi,

Some update...
Silicon valve cover gaskets are the deal (in my case)!
Dry as a bone;-)
Did not even have to re-torque yet.

Cheers,
Bart

last update:
no dripping what so ever!
I read a lot of different stories, a lot of them were negative which made me hesitate.
however in my case(read posts above) they really do work flawless.

I will only update when they start leaking again, so no update is good news!

regards,
Bart
