Any GM 2.2 engine experts in readerland?

[Matt69olds]

Last year my son bought a 97 S-10 with the rompin stompin 2.2 engine and a 5 speed. A couple weeks ago, the engine started making some VERY bad sounds, it locked up tight on the drive home.

Over the weekend, I found what is quite possibly the most rusted out 99 S10, also a 2.2 but with an automatic. It runs and drives well, just suffering from a terminal case of tin worm infection.

The plan was to swap engines and scrap what was left. Pretty straightforward, until I had the trucks parked side by side. The 99 engine looks very different than the 97. My local salvage yard shows the engines technically don’t interchange, but isn’t sure what the difference is. Swapping intakes or exhaust is no big deal, but before taking either truck apart I’d like to know what I’m getting into.

I paid 400 bucks for the 99, I figured the 4.10 limited slip rearend and wheels/tires are almost worth that.

Anyone in readerland familiar with these engines? Thanks.

Hmm... I used to know the answer to this. But I can't remember. I'm almost positive it was more involved than just an intake and exhaust manifold swap though. I could take some guesses as to the major differences, but memory isn't really good enough for that either. Fairly positive the timing chain setup is different. Maybe. Lol.

For someone that "doesn't like" the later S10's, you sure want pictures of them often. You're nuthin but a closet round S10 lover, lol.

Its some sensors on the side of the block about middle. Dont remember exactly though. My best friends nephew overheated his late 90's S10 and i installed the new rebuild and was just about done when i figured out there was a knock sensor or ?? not present on the earlier core. Had to pull it all back out and return the new engine and have the original core built. This was over 20 years ago so dont remember exactly.

I would think since you are using a later core into an earlier truck, you might be fine.

Crank and/or cam sensors perhaps?

Correction: the engine, rearend, FACTORY wheels with decent tires is worth the 400 bucks. Especially once I send what’s left to that big scrapyard in the sky.

The 97 has some hideous aftermarket chrome wheels on it now. Not sure what brand they are. I’m sure whoever bought them originally was proud of them. I think they are ugly.

Great big steaming piles of horse excrement!!

After a few questions and some research, it appears the big difference is the tone wheel and crank sensors are completely different. There are other design changes, but that’s the big headache. I have little doubt the problem could be overcome, but definitely not worth the effort.

Anyone need a good running 99 2.2 engine?
