Another blue smoke from exhaust thread
When ever I enter the higher rpm's 5k+ I notice light blue smoke coming from my exhaust, and it smells like its running rich.
The car runs fine and we did a compression test and had 190 across. The car also seems to be eating some oil, which im sure its burning oil, but wouldnt the compression be down if it was?
The car is a jdm d15b swap running p28 fuel maps.

Re: Another blue smoke from exhaust thread (del sol1658)
not neccessarily, your valve stem seals could be bad and only when the valves open does the oil enter the combustion chamber, or only in the exhaust manifold. The oil could actually help the engine with compression, it can help the piston rings seal better. I would guess that it is just bad valve seals on the exhaust side. Appartently your valve seats are good though with the compression you have.

yea thats for sure, with valve guide seals a way you can check it is you can drive down a hill while decellin if black smoke comes out then its your valve guides, you can also try compression check again and take out all your sprkplugs and see if air comes out of the cylinder you arent checking, you can check your coolant for puetrolum or your pcv valve would do it
