Its a common problem, but it has to be adressed before your engine is done. That oil is comming out wear the distributor wonce was. The plentem, or what you call upper intake will have to come back off, in order to get the plug out to chg. the rubber O- ring on the plugWhen you get it out it will look like half a distributor with the gear on the end and the O- ring towards the top. Its located right under the throuttle on left side of engine where the trans and block meat. There might be enought room to get it out without pulling the intake i'am not sure. But thats where the oil is comming from manny an engine has tied up because of that leak.

Low oil pressure in my 1996 Buick park avenue


Replace the sender before you worry too much. Many times that is the problem.
It should either be located at the top of the block in back near the transmission or near the oil filter.

Remove the plastic cover over the top of the engine. on the passenger side of the intake plenum there is a senor (MAP Sensor). That sensor mounts to the top of the PCV cover. Remove the MAP sensor. Remove the cover and the PCV valve will be underneath.

My 2000 Park Avenue Ultra knocks when you first start it up, but goes away after it warms up. It is also leaking antifreeze. Do you know what may be wrong?


Late model GM cars are plagued with antifreeze leaks around the Upper Air Plenum gasket and also the Lower Intake Manifold gasket. This is brought on by Dex-cool antifreeze deteriorating the gasket materials. If the Lower Intake gasket is leaking, it may have contaminated your loil with antifreeze. If there is antifreeze in the oil it should show up on the dipstick as a gummy sludge. GM has issued Technical Service Bulletins to their dealerships concerning this issue. Check with your local dealership to see if they will repair it at no charge. There currently is no recall, so they probably won't. In that case, take it to a good garage and have it repaired. Don't wait too long. If the oil is contaminated, it will damage your engine from lack of lubrication.

The plastic piece is the upper intake manifold. The metal part is the lower intake manifold. Sometimes the gaskets go bad between the upper and lower intake manifolds. But usually the upper intake manifold is cracked and needs replaced.

Head gasket


These cars do not have head gasket problems you need to remove the sparkplugs to get the coolant out and replace the black upper intake manifold as they will leak coolant into the combustion chamber. Common problem.

If this is a 3800, Upper Intake Plenum or Lower intake gaskets are an inevitability. Head gaskets on these engines rarely go out! Seriously, don't get duped. I am doing the job on my grand prix right now. Google it for further explanation.
