I have a 87 Shelby Lancer, #800 of #800, which is also Evaluation car number 1. I love the thing. Something that it has always done is blow a lot of oil through the air box, air filter and my blow off valve. I am not sure why. Read up of it possibly being the PCV Valve. I have ALWAYS changed the oil regularly, so there should not be any clogging. It does not seem to be burning oil and there is no smoke from the engine, just a decent amount getting blown through. Any ideas or reasons this could be happening? I want to keep my baby in tip top shape.
