ok here is the deal i bought a saab turbo and there is two oil lines obviously one is the inlet and one is the out..... so here is my deal, they both have 2 outer bolts and one iner hole one is square and one is round. i think the square one is the drain, but when i hook it up to the mani the square hole is on the top. so my question is is it a big deal if the drain is on the top or can i just run the oil lines backwards any thoughts or ideas would be greatly appreceated, thanks and good bye

 

The square one is the drain and should be much larger than the inlet. have you tried to rotate the center section.

 

no but i will now
