Tracking an oil leak
« on: April 04, 2021, 01:01:48 PM »
I have done quite a few searches to figure this out to no avail. I have a small oil leak I need help diagnosing. At first I thought the leak was just coming from the oil pan or even the drain plug itself, but I have tracked to this part on the front of the engine. I just donít know what it is. Oil pump? My repair manual doesnít seem to tell me what this is either. Any help would be greatly appreciated.

This doesnít make any sense. I think this is the AC compressor...

Any help would be greatly appreciated. If I canít figure this out, Iíll be taking the car into the mechanic. Might need to do that anyway, depending on the problem.

It doesnít look like the leak is coming from anything above that AC compressor. Is there some sort of seal near there that could be causing this?

Here are more pics.

So the slow leak comes to almost a complete stop after the car is left to sit for a bit. Then when I take it for a spin around the block it starts right back up.

I was able to stick my phone down in front of the engine to get a better look.

Would any of these spots possibly be my problem area?

All right, well after a bit more photos I think maybe this is a bad oil pressure switch. I see wuite a bit of buildup on the oil pressure sending unit and the oil seems to be dripping down from this area.

When an oil pressure switch goes bad, does it leak like this?

Iím considering trying to replace the switch myself since they are so inexpensive. Anybody have any advice here?

This final post is for posterity.

It was indeed a bad oil pressure sending unit. I was able to record video of the leak while the car was running. I then replaced it with some struggles by reaching the area from underneath the car.

Anyway, this is now posted just in case someone else has the same problem in the future.
