recent problem found on a 97' Buick la Sabre 3800 ser II pcv valve was missing. the intake was replaced with a aftermarket upgarde. note a stuck pcv will also cause this problem as well as a vaccume leak in the lower intake gaskets (port to crank case) back to the pcv .. the pcv is located on the passanger side upper pletum (intake) in a twist lock cap with a manifold psi sensor on the top of it. to check the pcv valve remove it and shake it.. ir should rattle if not replace it for that matter for the price replace it any way note the o-ring on the bottom of the pcv valve it dose not come with a new valve match the size and diamiter any o ring will work.
this car came into my shop for what sounded like a serpentine belt squill. but infact what was happing was the engine was under serveir vaccume and was causing the rear main seal to go dry and suck vaccume past the lip seal. dry seal and engine rotation was the noise.. i you out and maby others also..

Oil pumps are generally located in the crankcase. You must remove the oil pan to get to it.

The crankcase is located behind the engine and to the right. Next to the battery. Since the model of your 1982 Volkswagen Beetle the crankcase has been moved to the left next to the turning signal fluid. This has caused many issues with the fluid running into the crankcase. When changing the ventilation tube you must first disconnect it and then blow very hard on the end of it to make sure no fluid or dirt has been clogging it up. Since this is a positive crankcase and not a negative one make sure to not get frustrated while doing this process as this may make your crankcase negative and that will cause more problems down the road.
pcv stands for(positive crankcase ventilation)it relieves the pressure in the oil pan. it is located on the front valve cover close to the driverside of the vehicle.
