Nope not Power steering fluid. I don't think it would be the valve covers, since I don't see anything up top. I did put a new timing cover gasket in when I first put the motor together 9 months ago. Spent damn near $300 on a full gasket set. But I haven't done it since. And the PCV valve I am not positive. Where is it at? And how the hell whould it cause this much oil to leak? it has been leaking since I put it together 9 months ago. But just recently has it saif FU and leak like a sib.
