i have a '99 passat 1.8t. i have some oil problems. i bought it this way. the oil pick up screen was cloged, cleaned it, put it back on. still no oil pressure. now i don't know if the oil pump is bad, or the engine is cloged, or something else? i'd like to test it first, to see if the oil will flow through the engine. only after that i will replace the pump. there is no oil whatsoever at the cam bearings. and the engine makes a really bad knocking noise. what should i do as a next step?
any advise would help. and thanks in advence.
