Remember from school, i before e except after c.....dieseling

I would think that it could, because dieseling is detonation and detonation can cause a blown head gasket. It's like a sledgehammer blow to the crown of the piston too, so could crack pistons and rings or at least smash the top ring land and pinch the rings so that the motor has insufficient compression to operate properly.
