i have a 13b s4 i bought from some guy that sead he rebuilt it so i took the exhaust manifold off to look inside it and first thing i notest is that he cut the exhaust baffles out. and i turned it to check for compression and the back roters chugs wernt quite as loud and the whole inside of the engine is coated in oil like the apex seals are just drenched in oil . it looks clean though like it was rebuilt .but i wanted to know if all that oil would afect its compresson , like if i turned it on its sides and kranked all the oil out would i hear better compresson. and is there any way i can check to see if the engine is ported .
