Wayne-

Well I've changed plugs and I'll check the torque on them again...

The intake gaskets were just changed, so I'll keep that in mind...

The Oil Cap is original, I'll see what that looks like...

I'm hoping it's the intake elbow, but I was thinking that was more of a problem with the 3.0 liter motors?

I guess it's just going to take some trouble shooting time with vacuum lines.

Thanks,
Jim
