Why is my 1994 stock turbo IDI smoking so bad?!

[tapdancewilly]

At idle it smokes a bit, i guess you could call it normal for a 200k+ mile idi. But on the highway (any rpm over 1000) it smokes so bad i cant even see the people behind me! its a grey smoke, with some black, at idle its more white/grey. Smells a bit like oil, rebuilding the turbo to try and fix that(o rings are shot). Any ideas why its doing this? I just bought the truck and dont know a whole lot about it or the IDI in general.

white/grey indicates a problem with the injection pump.

Check the air filter.

Ordered a new air filter, and should I just replace the injection pump? Maybe just re time it?

Ok, so ya just got a 94 IDI. Your gonna rebuild the turbo. But why? Are the bearings froze up? Is there excessive play in the shaft? Does it show signs of scrubbing the side of the horn? Can you see lot of oil in it? Is there oil out the tail pipe? If the turbo is not spinning or is slow, it's possible the PO jacked up the IP (Injector Pump), that may be the cause of the smoke. If the turbo actually needs rebuilt, I wouldn't do anything else until it's back on, then see what might be wrong. Take a pic of the engine, post it on here. Could be the IP has been changed and it needs timing, IP timing is important. After 200K it needs to be re-timed anyhow.

I attached some photos. As you can see there is literally oil everywhere.

before you do anything else and spend anymore money, it would be the best if you spent a few days reading through our FAQ section( it's the threads tacked to the top of the page) and find the IDI tech articles and read through those. There's a mountain of info that will give you a basic understanding and help you inmensely in asking questions that would get you answers.
good luck!

Poor kid sooooo...anxious for answers has two near identical threads going....can we close this one and keep the other one open? Then it's less confusing?
