Have looked through the search facility and can not find anything particularly relevant so, question out to the masses....
I have always had oil residue coming from the intake elbow by the throttle body since I owned the car in 2013.
Breathers have been cleaned previously, small air breather hole in the manifold as well.
Car has the modified breather (flame trap box) and breather metal pipe to block removed and cleaned
Idle is good
Cam cover had been removed previously and completely cleaned out through all sections about a year ago, (they were blocked as you would expect), gasket was not leaking when removed, nor now
ISCV is not blocked
Emissions are good 0.03% CO, 14ppm HC.
Oil level only goes down due to leaking front crank seal.
Logically, this would have positive crank pressure but I can see no obvious reason unless it is so obvious I am missing it. I was under the car the other day in work and noticed that the whole bottom of the inlet manifold is soaked in oil residue so, as I like clean engine bays, this is unacceptable and needs fixing.
My old X20XEV Cavalier used to do it as well but that was sold before I could be bothered to look at it.
I have a few days off before Christmas this year (1st time in 17 years) so want to get a few jobs done on all the car.
Front crank seal being done, levels all checked and car to be gone through completely if possible (hence trip to ramp in work last weekend). Will be rechecking all of the above anyway as a matter of course) but any other thoughts or ideas are welcomed.
