What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Looks to me like the threads were already stripped and somebody helicoiled it and that failed as well. Need to figure out a fix that doesn’t involve pulling the pan or replacing it.

I would have expected it to pull the helicoil out in one piece, but yeah it does look like that to me too...
next size up if true...
not good.

The difference before and after car is negligible so it doesn’t matter

Yup. Most dynos use one that sits in the tailpipe.

When I first got an Innovate portable wideband system 15 or so years ago it had a tailpipe clamp for it to sit in the tailpipe while you drove the vehicle to get test readings

No kidding?
I understood it would fk with your output.
I figured it would show lean or some nonsense.

it would be much easier if i could install downstream more.

otherwise, things...
but we don't talk about fight club.

No man. It’s like a .02 difference in lambda. That’s why it’s negligible.

Is it getting hot in here or is it just me?

First time out with the hood Louvers on thecopcar. It’s definitely at operating temp after driving an hour. I stopped for a bite for both dog and me. AC running because it’s humid out. I’m watching incoming air temp. It is above the ambient temp on the dash sensor. I hopped out and held my hand over the hood to gauge that, then over the louvers. Heat was boiling out. In other words it’s working for what I wanted.

Anyone know where the fuel pump relay and or fuse is?
Under the hood i see a spot where it says it should be, but i don't see a fuse in the location nor the little square relay or breaker looking thing...

Rotated the tires.

While I had it all up on jackstands I looked more in depth for the oil leak. I'm 90% sure it's coming from the oil cooler line block on the side of the pan.

Now debating if I should just replace the gasket or replace the entire line set. They're like $95. Mine has some black residue gunk up where they transition from hard to rubber near the power steering reservoir. Not sure it they're seeping or it's from something else.

Also, whichever one I do, can I just unbolt the front driveshaft U-joints and let it hang to get room to get to that oil cooler line block?

This is why I got rid if my 1st work van. I should've made the moron garage fix it on their dime, but I was pretty much done with that van because of the rust it had.

Don't think you have either. I think that is taken care of with your FPCM.
