So I noticed my oil pan was cover in oil and after further investigations I tracked it down. It was coming from the front passenger side of the pan. So I decided to replace the oil pan gasket. It wasn’t the hardest job I’ve ever done just very time consuming. A few days have gone by and I notice the oil is still leaking from the same area 😒 anyone ever have this happen? did I miss an important step? Could it be the timing cover that leaking? Any help is appreciated. Thanks.
I changed my oil pan gasket on my 2007after looking at a Youtube video I used Permatex Black gasket sealer on both sides before install and no more leaks. The leak issue seems to come from the pan corner sealer that GM uses dries out and begins to leak. Did not notice any leaks on my timing cover when I changed the pan gasket.
Not aware of any "Upgraded" oil pan. The urban legend for "Porous" oil pans was just the OEM gaskets leaking and running down the sides of the pan. Dealers want about $900. to change the pan gasket, I did mine for about $80, but it took several hours having never done it before.Now I could most likely do it in about six hours having done it once before.

Yeah, it definitely could be the front timing cover seal. I'd recommend adding UV dye to see where it's coming from. It doesn't work quite as well as you'd think but should give you a pretty good idea of where to look for the source of the leak.

yea I put the dye in and saw it glowing around the front passenger side and just assumed it was the oil pan. I really hope it’s not the timing cover. The previous owner had the harmonic balancer. He should have just replaced the timing cover gasket while he was at it. SMH.

Did you apply dabs of RTV sealant at the four intersections of the cover gaskets (front and rear) with the pan gasket?
Well... If anyone is still paying attention to this thread, here is an update for you. I tore it back down and this is what I found. Video and Pix - I believe I damaged the new seal by removing it to install the alignment tool. And... I believe the ribs on the outer edge of the seal designed to seal and hold it tight inside the housing are worn off from it being installed, removed, and re-installed again.
I intend to put a new seal in it, install the flywheel, run it with open headers for at least 30 minutes to check it *before* putting everything back together.
Any thoughts or disagreements from any of you? Thanks in advance!
It's fixed. Replacing just the rear main seal fixed it. I must have damaged the *new* seal that came pre-installed in the new rear cover. I removed it to install the alignment tool. Once replaced, it's bone dry, even after a 450 mile trip in the car yesterday.

Glad you got it fixed. I don't know where you bought that rear cover with the pre-installed seal in it, but they obviously aren't well informed on the process for installing a new cover and seal. If I were you, I would call them and complain and ask them to refund you the cost of a new seal, if not your labor to do the job the second time.
