Sure sufficient, as soon as the heads come off, Eric finds the 2 forwardmost pistons are now not correctly secured to the crankshaft. He additionally discovers they’ve beforehand made contact with the top — one thing that is not speculated to occur in regular operation. Taking off the oil pans reveals a ton of torn-up rod bearing materials, together with a number of large chunks. That explains the free pistons, then.

Taking the pistons out reveals a bunch of burnt metallic on the backside of the connecting rods and a bunch of injury to the cylinder partitions. When an engine is overfilled with oil, the crankshaft splashes the surplus oil round within the crankcase, turning it to foam. When that foam is sucked into the oil pump it aerates the oil to the purpose the place it could actually now not lubricate the metallic. The result’s a bunch of friction and warmth that, left untreated, will rapidly kill a motor. And that is precisely what occurred right here.

Take this Jaguar V6’s destruction as an indication to learn to test your oil correctly. Or you possibly can find yourself with a bricked engine.
