Dexcool sucks. When I got my 99 Tahoe first things I did was flush the coolant system and convert the CPI to MPI.
Yep, Avoid the Orange ****. Biggest problem with it is, it loves loves loves to eat gaskets and it don't care which ones either. Most common for eating upper intake manifold gaskets on the V6's. Or at least helps play a part in bad design. All those damn 60 degree V6's should have been recalled but no didn't happen. Another GM problem that'll get swept under the rug for ever.
You did the lowers too? I mean, that actually makes more sense. I often wondered how it can be blamed on Uppers. I just know it's a common problem and an expensive one. Just about everyone I know with a 3.4 had to have them done 65,000 - 85,000 miles like clock work. And some 3.1's too but EVERY 3.4 I know of that friends had needed intake gaskets. I remember one guy who got a new/used Grand Am GT with Ram Air, he said, it hauls ass and only has 40,000 miles on it.
I told him he should have gotten a 4cyl cuz he'll be hauling ass to the GM dealer to get intake gaskets done and overheating problems out the ass in about 30,000 miles. It was about a year and half later, he calls me up. "YOU MF'er, you jinxed my car. I got water in the oil, GM says I need intake gaskets" I asked how many miles were on it, he said 72,000. I missed it by 2000 miles. Dude has hated me since cuz I bagged on his POS. I told him, Grand Ams and PT Losers are the most towed cars. I mean lots of Taurus too and other models, but there's a **** ton of them sold. PT Loser by far is worse than the GA and Olds Alero, but still, they're pretty damn bad. JUNK.

Poetic justice......
Yup, Coolant doesn't make for good bearing lubricant.
Oh but it cleans piston tops and cylinder walls nothing like a good steam cleaner built into your 3.1 lol.
They should be able to braze one in unless it has plastic tanks.then maybe epoxy.
