hey all,

i have a next to standard 4k-c with extractors and 32/36! it has breaths so much oil out of the rocker cover breather....

My catch can ends up being half full after every race meeting? So i thought screwed pistons rings coursed this, so i did a compression test and it has 150-155 in all 4 cylinders!! What else courses blowby?

 

cheers

Worn valve stem seals.

pheww i hope thats what it is... chucking a set of those in anyway!!

 

Cheers

compression is escaping somewhere probably past the rings.

Spell it with me, C A U S E S, causes.

 

 

Obviously the education system doesn't teach this basic shit anymore so I guess its up to Rollaclub to save the world from piss poor spelling and grammar.

Blowby can come from 3 places, head gasket blowing into oil return, valve guide seals, rings, even if you fix everything perfect it will still blow oil out so work on your catch tank first, make sure the rocker cover is baffled properly and that it goes to the top of your tank, there MUST be a return to the sump above oil level, this comes from the lowest point of the tank, it may fix your problems. and try spell check

Spell check wont fix that, the word was still correct!

there was no need to be an arse about it, I'm sorry i can't spell :P, thanks for all the info i was hoping i didnt have to do rings ;)
