Hi and thanks for looking

i have a 2wd saf running stage 3 with armed chip etc and i cant get the cam seals to stop leaking

replaced the seal (with VITTON once) twice and all the o rings etc

all the caps are tightened to the right settings

the leak seems to be more on the right side cam and less on the left and it leaks more if ive driven the car hard?

i also get a little white / blue smoke from the exhaust after a hard run and come off over run say slowing down form +70mph after a fast bit ? not sure if its related

I've checked the breather system (kidney box) also it have a bailey breather system with a pip off the cam cover cut out an the back also

other than that the car runs and drive great no smoke on start up and normal driving , only off over run when had a high boost

any help or ideas what to check and help with diagnosis that would be great

 

..change cam bearing spacer..it is probably worn..

 

No sealant between the cam cap and head.

 

replaced them to

 

yep def sealant used two types as was leaking after the first time so thought the same

 

check the cams dont have a bend in them, maybe the nose is not sealing correctly against the seal.

 

will do next time its apart cheers

 

Do you have sealant over and around the half moon seals as they usually leak? If it's indeed leaking from the cam seals and you have replaced them there is one thing to try aswell. There is a circlip over the cam bearings which has ~5 mm opening on it and it sits in a groove. I rotated the circlip so that the opening is upwards, instead of any other way. Don't know if it makes difference but I did this.

 

yeah will try that cheers

ill look at adding more sealant to the half moons too

 

Use a blob of Loctite 5910 at the ends of the half moons where they touch the head. That will do the trick.

 

cheers did that still no luck

 

I know this an old post but did you ever sort it. Im struggling with mine.
