Dude you not kidding about that hard to work on 3.4. I had to put an alternator in a guttlass supreme about a year ago. Man did that suck. The main seal was shot so there was oil all over and I had to drop the rear section of the cradle to get that bastard out. I hated that job. The car she raced might of had a 3.1 in it too. Also the 1990 model year W bodies had a rare 3.1 turbo motor factory. Had a non intercooled setup with a t-25 garrett on it. What a fuckin bomb those were. I think they were produced for like a year or 2? later, matt
