Re: no compression = no power
Any corrosion/errosion around the cylinders, water ports, and oil ports that happens in the head can and does happen on the block surface also.<br />If water goes past the port in the head gasket and leaks into the cyliner and the head shows a defect at that point, then the block probably shows the same problem.<br />Use a GOOD straight edge (Not your Home Depot $2.99 tri square to check the flatness of the block. The service manual shows how to check it.
