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

[iamdub]

What sensor is on the drivers side of the block with the white connector, just forward of the oil cooler block?

@Doubeleive @iamdub does the knock sensor go into an oil passage, or all the way through the wall of the block? Basically wondering if it can leak oil

Lol

I actually had a second half to my reply saying "No, it does not go into the block. The hole is blind."

I erased it to save myself from at least one instance of coming across as a díck since your question may not have had anything to do with leaking oil.

if there is oil there it is probably coming from the valve cover, get some purple power and clean it all up and then keep looking after you drive it a bit

Either that or the oil cooler block gasket. It's real gunky on the top side of that block and in front of it, and it get oil accumulation below that cooler block and on the oil pan bolt heads under the cooling block.

Going to change out that gasket first, it was $5 and will probably do it Saturday.

It doesn't leak enough to leave a spot on the ground, it just lightly coats the sway bar, area around filter, and bottom edge of pan/bellhousing.

I had one of those rear rack carrier things with a snowblower on it and I got a ***** warning from a cop, says it's blocking the license plate.

I have one of those carriers, i have been wondering if i'll get poked at for it.

Yup, as others noted.
Knock sensors.
I remember those things well.

Installing my new ones with the new engine, they have to be clocked just right in order to line up with the harness.

And no, there is nothing that could allow a leak through the block.
They looked like a grounding location if you didn't know what should be there.
