My son has an old '94 Caprice Classic with a 4.3L L99 V8 engine. He states there is gas in the oil, anyone got some recommendations as to what I should be looking for here? Stuck injectors, bad pressure regulator, or otherwise?
FWIW, that wasn't what I meant.Diaphragm on the fuel pressure regulator wasn't busted, no gas getting into the vacuum there.
