Just did a dry compression test on the 92 945T. Warm engine readings from front to back (3rd compression stroke readings) 90 psi, 90 psi, 0 psi, 0 psi. On the two cylinders that had readings they went up something like 40 60 90 90 for the four rotations. All readings were at WOT.

Symptoms leading up to this were slight pinging which progressed to full blown detonation sounding, missing and lack of power. Definite miss at idle but the wagon got back home. Now that is is warm I've got a chance to check it out.

Planning to pull the head next as I believe these all indicate a blown head gasket.
