2007 Tahoe 5.3l AFM DOD delete thread

What type of plug for pressure relief valve? Could I just find a bolt that matches and plug with that?

Growing up doesn't have to suck

I have the high lift version of that cam in my 6.0 and it sounds basically stock even with long tubes and full dual 3" exhaust. Granted it has a massive flopro mufler and "highflow" cats. A buddy has that exact cam in his 2002 5.3 with stock heads and swears hes never driven a more "peppy"...

Anyone have the correct torque for the oil pressure relief plug? I keep searching and getting mixed answer from 20ft lbs to 29 ft lbs.

1 1/4 grunts will do. Seriously- it's not a structural item. Aim for the middle with 25 ft. lbs. or just go as tight as you can get it with your hands on that hex wrench. Use red Loctite on the threads and never give it a second thought. For reference, GM's spec for the oil drain plug is 18 ft. lbs. This is about the same but with pressure on it. 20-25 ft. lbs. with thread locker will be plenty.

I tightened it by hand with some Blue loctite thanks guys. I'll wrap it up Sunday afternoon and give a start to see where the oil pressure it at.

I have a small oil leak shown in the picture below. I assume you pop that lid and replace?

That's in inspection hole cover. You pop that out to see the flex plate, torque converter and rear main seal. If engine oil is dripping out of that, then you have a rear main seal leak. Red oil would indicate leaking transmission input shaft seal.

I figured that be the next thing to do that I may have a shop handle. How's the difficulty of that? Would throwing a newer tyranny in be a wise choice also?

So far after replacing oil pump, and installed newer oring(green) my low oil pressure has been solved. So I can finally say this AFM delete was a success and hope this thread can help years to come with my questions and the answers given by you fine gents. Special thanks to Iamdub and Wsteele stayed the whole process with me.

Next repairs will be suspension may go with a RC lift, and rear main seal.
