recently swapped out my b16a2 from my 99 Sir do to spun rod bearings. Used the same head and put in a del sol b16 jdm block. ran fine after starting it up, and once i looked under the hood i noticed it blew out about a quart of oil from underneath the intake manifold around the oil cooler. it has all new gaskets. any ideas what might have happend?

 

I know it seems pretty basic but is there a chance you didnt get the filter on straight and it didnt seal nice and tight? Like perhaps you cross-threaded it? Just a thought

 

well id clean it and see if you can see where its coming from........if not try adding linetrac......the oil dye that can be seen with a blacklight..........
