Hi everyone, first time posting, but long time reader. I usually try to avoid posting when I can, and just browse the threads and read about related problems and figure it out from there. Even though I've found many threads that are similar to the problem Im having, I still can't narrow it down to my next step. so if anyone can help, it would be greatly appreciated. Ok so, BAD oil leak problem with my friends 2005 GMC Sierra 1500. It's had this leak for a while, but it's gotten to the point now where it's starting to leave puddles. I power washed the entire area, and I actually got it pretty clean. Today when I looked again to see if I could trace the source, I had a much clearer picture of where the leaks are actually coming from. From what I've read it seems as though it could be the valve cover gasket, the crankshaft sensor, the rear main seal, or even the oil pan gasket. My problem is that to me, it looks like it's coming from almost all these places. I looked inside the bell housing and I don't see it looking completely soaked in oil. It does however, look like the leak is mainly coming from in front of the bell housing behind the engine, in between the two. I'll attach some pictures. These would be from overnight after I power washed it, so the oil hasn't blown anywhere from being driven or anything. Thanks so much to anyone who's got any ideas!

Hi, I have an oil leak coming from somewhere near the front of the engine on my 2006 Chevy Silverado 1500. I noticed it was making a puddle towards the front of the truck. Anything tips is helpful!!

My 2000 GMC Sierra 1500 (4.8L V-8) has developed an oil leak somewhere above the oil filter (not the filter itself). I cannot see any leak around the valve cover (both gaskets were replaced recently) nor around the head gasket. I have not been able to examine it from below very well yet but I'm wondering if the filter housing is a separate part attached to the block and uses a gasket rather than being machined into the block itself. If not a separate part where the gasket can fail I have no clue where the leak could be coming from. Can someone confirm my theory or suggest where in that area a leak might originate? TIA.

Good morning All! Looking for some help for my son's 2012 Silverado, 4WD, 5.3L. I have attached a video of a pretty bad oil leak my son has on hi truck. Video is BEFORE any repairs were attempted. 1. Son thought it was the oil pan gasket, so he went through the process of removing front differential, and other parts to perform repair. Halfway through disassembly he realized it was NOT the oil pan. 2. He then thought it was the rear main oil seal, so he put truck back together, and had it towed to my house. I spent the last 3 weekends figuring out howto, and then replacing the rear main cover/seal. 3. Started truck and still $%%& leaking! Son shared this video with me, and I viewed it several times now, and based on what I saw under the truck and the video, this looks like the oil pressure sender, or something up higher. It is clear to me now that we worked on the wrong thing! I am about ready to pull all the remaining hair out my head on this, and was hoping someone could view the video and give their thoughts? Is it the pressure sending unit, or possibly a valve cover (I doubt this, but possible), or intake gasket? It is now below freezing in Michigan, and I do not have this truck in the garage (I WAS in the middle of my rebuild on my 1985 Camaro, so I have no room, and need to get this truck fixed, or towed to a shop if it out of my abilities).

I have a 2011 Silverado 4.3L. Im slowly leaking oil, appears to be near the timing chain cover. When I noticed it I was below the low line on the dipstick. Have not seen any oil drips on my driveway but if you look around the timing chain cover and oil pan there is always a thin layer of oil. Ive had to add a quart of oil two weeks after topping it off. But there has been zero drips?!?! Can't figure out where it's going... Has anyone else had this issue? (Parked in the same spot on a clean driveway when parking and checking the oil level)
