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!

Hello all. I have a 2013 silverado w/5.3l flex vin 7. Basically has rough idle in park and drive. Very poor acceleration. Almost seems to bog down when trying to accelerate. It will occasionally surge and for just a split second I can feel a bit of power. Also doesn't want to downshift when I lean on the gas pretty heavy. I've got to do near floor it to get it to down ****** and when it does it will drop down 2 gears a lot of the time. No engine light and it won't set any codes. Showed 0 misfires on all cylinders. Long Fuel trims usually in single digits negs. Fuel pressure 43-46psi at idle and highway. I've replaced throttle position sensor, Accelerator pedal position sensor, manifold pressure sensor, mass air sensor, plugs, coolant temp sensor, oxygen sensors. Fuel pump, intake manifold gaskets twice (now with "updated" steel gaskets), throttle body gasket/seal, injector o-rings (upper and lower). Tested all coils for strong spark. Smoke tested for vac leaks along with propane. It has never failed to start or even had a long start and has never died/stalled. I'm just kinda at a loss at this point. Any help will be appreciated and possibly considered. Thanks
Hello Everyone! Before I get started I want to thank anyone in advanced who responds with pertinent information.
I'm looking for a replacement exhaust system for my 09 Silverado 6.2L 4x4 Crew Cab/Short Bed. My current system has lots of rust (living in MD, they heavily salt & brine the roads here) and has sprung an exhaust leak right behind the muffler on one of the pipes.
I've been searching around (thought it would be easy to find a system) but have not had luck in finding what I have been searching for. There are plenty of systems for 5.3L & 6.0L motors but scant any for 6.2L.
On my truck currently is an aftermarket cat back system that was there when I bought the truck (not sure which brand.) It is a single in / dual out muffler with dual pipes going out the bumper.
What is the factory flange diameter at the end of the factory Y pipe? I'm seeing conflicting information (this will help me determine what muffler to buy if I piece meal a system together)
If you have any suggested systems, here's what I'm looking for
Material: 304L Stainless Steel
Configuration: Dual exit at rear bumper
I'd consider a long tube header setup w/ high flow cats as well (I would like to maintain all emissions equipment) any suggestions there are also welcome.
I can always get a quote from a shop but I wanted to shop around first before I did that.
