What did you do to your NBS GMT800 Tahoe/Yukon Today?

And the driver's side -

Compared to the passenger side head, this looks to have more build-up.
Should the passenger side be oil-stained?

Now either I caught this soon after the problem started or something else is going on. The oil didn't look too bad in the drain pan -

At least it didn't have any chunk or globs in it.

I think I will just give the covers a good cleaning, finish the oil change and drive it for a few miles and recheck.

Here's the Castech mark.

Would a catch can help this? That DS is looking pretty rough.

So my truck still has severe lack of power (no codes) however I floored it yesterday and got P0102. I looked it up and it seems like I may have bad cats after all. One of the causes for P0102 (Maf Sensor - Low Circuit) is clogged cats and seems to be consistant with lack of power.

I think I'll be making a call to the exhaust shop again to have new cats welded in.

Question for the group. If it cost 250-300 per car welded in is it worth it or just buy replacement pipes online?

Took care of the trailer hitch yesterday after the recommendation here. Came off easy with 8 bolts - took a scraper, wire brush, and sand paper to it, then sprayed down with a couple coats of rustoleum black. Not perfect, but much better then before and I'm happy with the result

Are those the LED taillights or the regular bulb setup? I’ve been thinking about getting a set for mine.

Whichever way will give you better quality cats. Ideally, OEM cats are best. But, many people's budget doesn't allow for them. Just know that you pretty much get what you pay for when it comes to cats.

Personally, if it's a $500-$600 repair, I'd hollow them out (if you have visual inspections) or remove them altogether with one size smaller diameter pipe in their place then get a tune and have them taken outta the programming along with all the other usual tweaks.
