This is my first post so i hope all goes well. I have an 87 t-type that has been sitting in a garage for the last 8 years. Surprisingly it started right up and ran extremely rich. Upon inspection I found the turbo to not be spining I could barely move it with my fingers. I'm assuming from sitting for so long the bearings dried out. What I need to know is from your experience does my theory sound right And if so where can i get the parts to fix it at a good price. And are they any other common problems I should look into while doing this. Sorry for being lenghty but i figure the more info the better your respones

Turbo not spinning means clearance not correct. I think you're better off having turbo either rebuild or buy a new one. Find someone with knowledge of the turbo cars to look at it. Go to
Resources-Technical info-Turbocharger. Also in Tech section-Buyers guide. Read both carefully.

If the car infact has been sitting for that long without being started,....its more than likely rusted shut! lack of oil and to much moisture. where are you from? There are going to be alot more things you are gonna have to do befor you actually get that thing back on the road without hurting somthing...and dont be supprised when it starts leaking everywhere!

The car has unforunatealy been sitting there that long (well at least the miles are low) I live by Rockford IL. I know it ran fine before it was forgotten. Anyway, If i tear it down were should I look for rust and check for clearances would plastigauge strips or a feeler gauge work to check for tollerances between rotating parts and casing (bellhousing or whatever its called) If so what are the tolerances it needs. Not much help to my problem ,but I'l soon have a turbonetics
T-04b turbo will that work with the buick? Thanx for helpin out

Wait a minute, you dont want to physically take the turbo apart. To do that properly you need special tools and the knowledge to put it back together right. Youv'e heard the expresion " if you have to ask you probally shouldn't do it!". You say its spins but you could barely move it. Sounds like the CHRA is coked up with old dirty motor oil. Being the cheap ass I am you might try pouring some type of solvent or crankcase cleaner through the oil drainback( were the corragated tube thats held onto the turbo with two bolts is) and let it sit for a day or two. If its not to bad it may free it up and the only thing you have to worry about is a dried up seal. If thats the case you are going to have to go with a rebuilt or new turbo. If it is the stock turbo check with your local big diesel truck parts dept and see what they charge to clean and rebuild it. The last one I did cost me under $200 to do. Oh yea check to make sure your turbine and compressor housings and impeller wheels are in perfect shape, no obvious bent fins and scored housings. If they are bad you have to go with a complete turbo.
