    Oil leak coming from head around exhaust manifold. Any opinions?

    Pretty much what the title says. I have an oil leak coming out between the head and header. Wondering if it's just the gasket. Will do a compression test this weekend as my father says it could be a piston ring.... I thought I'd come here for any opinions first thanks.

    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...

    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?

    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?

    2007 Tahoe 5.3l AFM DOD delete thread

    I would say that pressure seems about right but would let a more experienced person around here confirm that. My problem could be not related to the oring I pulled pan today and tomorrow I pull the timing cover/oil pump to inspect oring and change pump

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

    Found someone with similar issue "Installed on 2007 Tahoe 5.3 Flex. Had the hard o-ring issue on the oil pump pickup which caused low oil pressure for the first 10 minutes after cold start. In my slanted driveway idle pressure would drop to just above 0. Once the oil was nice and hot the...

    2007 Tahoe 5.3l AFM DOD delete thread

    AFM already deleted. I'll probably just plug the pressure relief valve. On one start up today I let the low oil pressure light come on and then revd the engine up and immediately oil pressure went above 50psi and stayed. So I wonder if your pressure relief valve theory being stuck open could be...

    I did reuse the old pressure relief valve. Would this be a good place to start or change the pump first to the M10295? Electrical I did leave one harness unplugged that plugged to old VLOM that was for the AFM. Would an oil pressure test be of any worth?

    2:30 oil drops to almost Zero 4:30 minute mark is when the oil stabilizes.

    The oring I inserted was the green one and it fitted snug enough where it didn't even feel like it had to be bolted on the pump. So I'm hesitant to blame the oring.

    2007 Tahoe 5.3l AFM DOD delete thread

    When starting it, the pressure will shoot up to 40-60 psi and slowly drop down to zero then I get the low oil pressure warning light. After driving around for a couple minutes the pressure stabilizes above 40psi.
