Thanks Joe!

I looked at his engine build thread, and this post shows that piece is in fact installed in his block.

ROFL

I guess I could try 50w although 40w did nada. I'm trying another trick too.

Thanks all, I didn't know what that was either, and thanks Pat for looking up the pic for me!

I blocked the cam cover dumps with JB Weld and drilled to 1/16" which raised idle pressure ~5-8lb but max pressure still 40lb and not enough for VVT operation.

VVT will not operate at 40lbs, huh? That's interesting.

What do you infer from this?

I would just assume that 40psi would be adequate to actuate the system. 40psi is within the parameters of what I would consider normal oil pressure.

It's very slightly below the lower end of the spec (warm @ 3,000 is quoted as 43-56), however it should certainly be adequate to operator the VVT mechanism.

The engine light comes on at ~2500-3000 & ~30-35lb. The VVT may function at higher rpm tho.

That seems reasonable.

(I assume that the CEL is for P0012.)



Just to double-check, you are using engine oil in your engine, and not Italian salad dressing, right?

Soo, did you ever figure this out? I'm going to look at a car this weekend with a P0012 but maybe I won't bother if it's this much of a pain in the ass.
