Well after continual flogging I was able to beat the turbo 200 into submission and it will now require some repair or at least a few stitches.
I bought a brand spanking new, 25 year old turbocoupe to use as my daily driver in the spring and have thus only been using the Fairmont for weekend runs to the store and for a quick cruise or whatever. As it is no longer my daily driver, it is easier for things to get overlooked, you guys probably know how that is. Well long story longer, the boost line to my boost controller came loose while I was "gingerly" merging onto the freeway with my foot through the floor and banging gears like I was trying to break something. The car was pulling incredibly hard and when I looked at the boost gauge it was over 20 psi, so I instantly lifted but kept driving and it actually seemed OK. It was not smoking or making any racket, but when I got off the next exit laughing maniacally and wondering what happened with the overboost I was thinking this engine was indestructible and I thought it was awesome. I was wrong.
As it came down to idle speed it had a noticeable miss and when I popped the hood there was a giid amount of blowby smoke emiting from the breather. The wideband was reading abiut 11.5 at idle due to the dead cylinder. Although it idles rough it still runs surprisingly well, but she is a goner. My guess would be detonation damagw due to running the cheapest liquid that resembles gasoline and the over boost problem due to a 50 cent hose clamp not being tight. I am figuring busted rings or pistons or both and with any luck I did not ruin any cylinder walls.
Oh well, I told you guys I would report if and when I broke it so I did. I will update with carnage reports and photos just so anyone interested can know what to expect from 20 psi of manifold pressure and 87 octane gasoline. Hahaha.
Cheers.
