After I removed oil pan and to get a bolt that fell down in it and then put it back on, I started noticing oil puddles forming under my car. I tried to pin point where the leak was coming from but, I could not locate the source. As you can see in the picture below, there is a lot of oil on and around the lower oil pan by the filter. If you look closely to can even see oil dripping from the wire hanging by the pan. I checked the oil pressure switch and although there was a lot of oil on the boot for the wire harness, there was no oil coming out from the switch, as far as I could tell. If you look at the other picture, you will see oil on the PS pump and the boot on the CV axle, but this has been like that for a while, long before the puddles started forming, so I do not think that this is the source. Any ideas?

 

was the oil pan gasket okay?

easiest thing to do is lift the car up, spray some soap on the underside, wash it all off, and come back in a hour and see where the oil is starting to come from. since it started happening right when you removed the oil pan, it would be pretty coincidental to be something else

 

Half moon seals from upper oil pan. Check middle of crank pulley and see if oil is running down from there.

 

Self induced IMO! Clean entirely, run and leak check your work...I'm sure when you first did it you didn't have it microscopically clean when your applied your sealant....the block will be still oily and contaminating the lower block oil pan flange and the RTV never seated/sealed to the flange.....spray brake clean inside the block to wash out out the oil residue being held in the block cast.....may take 4 -6 cans of brake cleaner, plenty of patience and a good compressed air source......It has to be clean and dry for the RTV to adhere properly...."DO IT AGAIN SAM!" GL!!!

 

Clean it good first. You can then add some oil tracer to the engine. I use this:

I actually just used this stuff to find a leak. I found that the leak was with the rear valve cover gasket. Here is a video I just took a couple minutes ago:



Good luck.
