1981 MB 300TD Turbo

[drainard]

I have found a 1981 MB 300TD Turbo to purchase, but when test driving it appeared the Turbo was not working. When accelerating there was hesitation and the oil pressure would peg then the vehicle would gradually gain speed. The seller wanted to make sure I was not knowledgeable about Turbo Diesels and proceeded to tell me all is fine. I guess my question is whether this is symptomatic of a bad turbo. and secondly how pricey is it to fix if I Do it myself? I used info from one of the posts to look at the mauals for the vehicle and have requested that he verify the engine and chassis number. Any help would be appreciated. In search of a vehicle to run on waste vegetable oil.

Thanks,
