It was the gaskets. Greg and the tech at www.driversimage.com did a great job. I highly recommend them for your VX needs. No more check engine lights or codes. The VX is back to its robust self.

It appeared from your previous post that the intake manifold gaskets were not the problem. Could it be that the manifold bolts were retorqued to the required 18 Ft lbs or more the second time around?Originally Posted by MachineVX
I ask because I am about ready to reinstall my rebuilt SC & new intake gaskets. When I removed the intake bolts & nuts the torque value appeared to be a lot higher than 18 ft lbs, more like as tight as you can get it + 1/2 a turn.
Incidently, my Throttle body had no GASKET installed
Neither ordinary or extraordinary, just indefatigable.

You might be right that it originially was over torqued, so I made sure this time that I gave them all the right torque specs, which I should have done in the first place.

Thank you for your quick reply. Perhaps undertorqued (13 ft lbs) The right torque specs being 18 FT lbs (Isuzu manual) & not 13 Ft lbs is that correct?

There's a TSB that changed the spec for the manifold bolts to 13lbs.

Thank You 13 ft lbs it is.
