He told me something like, when he rebuilds a TD engine for a Vanagon application, the reconditioned rod length along with the thickness taken off the block in resurfacing the head gasket sealing face and the head gasket thickness he uses results in a lower compression ratio. He only did a valve job for me, so he told me to use the next thicker head gasket upon reassembly. He does this for some reason related to motor life or reliability. I don't know whether the effect of the reduced compression ratio is increased motor life, or just a reduced probability of head gasket leakage. Also, I don't know the effect of reduced compression ratio on cold-weather starting. Mike
