The 3.1 has special lightweight alloy pistons fitted. They expand and contract at a different rate than the block, so for several minutes the engine will emit a knocking sound until the pistons expand to fit the cylinders. In addition, as carbon builds up in the "squish zone" on the cylinder wall at the top of the piston's travel, the piston will make a noise as it contacts the carbon until the block expands. This situation is perfectly harmless to the engine. Other than the leaky intake manifold gasket problem, this engine has proven to be quite reliable and a very durable workhorse.
