i had a compression check done and all cylinders give between 170-175 psi.
the problem is i blow oil out of the breather in the valve cover. my mechanic is confused too. i have changed the pcv vlave 2 times, both oem from the dealer. any idea as to why i have the positive pressure? it would usually be blow by but all the cylinders give good numbers?
any help would be great
Hmm im thinking that guide seals could be causing your problem. Oil will be able to pass through the valves without you seeing it on a compression test.
hey im having the same problem if you find the problem please post it to see if i can fix mine too.
i even rebuilted the engine and still has the problem
are the valves okay not bend or anything
make sure all ur sealants/gaskets are okay
check the plugs as well
i still have the problem don't know what it is.
my valves are fine. i have never lost a timing belt. the seal may be a diffrent story. i just need this motor to last until i buld a new one
well just spend a couple of hours looking at ur engine and seeing if anything is wrong
take off ur valve cover look behind the block right under the intake mani
is ur dipstick in place? is the long tube in goes into undamaged??
i'm not taking the valve cover off becuase i have to buy a new gasket.Quote:

Is it a lot of oil? Oil out the breather is normal, thats why they make oil catch cans.
it's good chunk. i never had the problem.
get used it, i went through hell and 3 pcv valves before i came to the realization that this is normal
I had the samr thing happening when I was playing the PCV hose and left it unplugged of the manifold. Since I fixxed it Ive never had any oil in the breather. Check for the that hose being clogged
