Slight oil leak appears to be coming from oil sensor

Re: 2008 Buick Park Ave. It has recently developed a slight leak (maybe a drop of oil/day) marking up pavement and my wife is driving me crazy to get it fixed. I have localized the leak toto the right front. After pulling the rt frt wheel and looking, it appears to becoming from the connection to the Oil sensor. I suspect the sensor is leaking, not where it is threaded into the engine, but where the 3 "posts" on the sensor are located. Does this make sense? Is the solution to replace the sensor? Is this somrthing I can do. Access is limited, but I was able to get a wrench on it and loosen it slightly, then re-tighten it. Do I have to remove the engine oil before replacig the sensor? How tight do I tighten the new sensor?

    Thanks for the help on the leak issue. I have not yet changed the sensor, but hope to soon (weather permitting), but I think it will solve the problem.

Replace the Sensor. You should not need to Change the Oil unless it needs it. Just tighten Finger Tight and 1/2 Turn with Wrench too assure no Leaks occur.

Gasoline is entering and contaminating the engine oil. It can only enter through the leaking injectors.
Inspect, clean or replace the injectors and replace the engine oil immediately.

97 98 buick park ave oil light blinks and stays on

The oil light is either a bad sensor or it's telling the truth that oil pressure is low. You can install a new sensor or hook up a mechanical gauge to find actual pressure. Cutting off can be caused by way too many things to list

Key won;t go into ignation on my 2002 buick park ave

It is possible that the tumblers in the ignition need lubrication. I had this problem with a boat ignition. Spray a small amount of break free, or WD 40 or graphite penetrating oil into the slot and slowly work the key gently into it. A drop of oil in the slots of the key won't hurt.

Possible oil Leak at Knock Sensor

if I'm not mistaken, the knock sensor is mounted on the transmission bell close to the motor and detects the flywheel position. It is possible that the valve cover gaskets might be leaking from the bottom side and dripping onto the knock sensor, but it is also possible that the leak might be from the rear main seal of the motor. If that is the case, you will have to drop the ****** to replace the seal. If the knock sensor was bad your vehicle would not start at all, just crank. Try to wipe all the old oil with rags and look very closely where it gets oily again

I have a 1998 Park Avenue. Sometimes while on the freeway i experience a slight drop in the RPMs and then the RPMs gauge drops off completely. What might be the problem?

The most common problem will be the cranksensor. Now does it start up right away. You may need a ignition module. crank sensor and module should be replaced as a single unit. If you feel like its wothwhile do the cranksensor cam sensor and ignition module you go to the market and the vehicle wont start. When my customer comes in for either component I always try to convince them when one goes the other will fail

Does the engine sounds like it is rattling when it runs? LIke the oil pressure is low. It might be a oil pressure sensor. If it is rattling then start with an oil change.
