About

I bought the Jimmy in 2004 as a second vehicle for my wife. I picked it up cheap due to some minor body damage and failing fuel pump. I had a local shop replace the fuel pump and drove it for church & such when the whole family was going. The body damage is minor. The driver’s front fender is slightly bent at the corner, the headlight lens is cracked (still works, though), the bumper is scuffed, & the grill is broken. Also, there is a dent in the driver’s side of the rear bumper & tailgate.

A year after having the fuel pump replaced, the intake manifold gasket started to leak externally (typical on GM's 4.3L V6). I was working at Goodyear at the time so I stayed after work & replaced it myself. When I was putting it back together I asked a more experienced mechanic to help me put the distributor back in to be sure I got it right. He took it out from where I had it & put back in the opposite way saying I had it backwards. When we started it, BOOM! Apparently I had it right, and he put it in backwards. It backfired so hard it blew the plastic upper plenum off the engine. I pulled it back apart, put in another new set of gaskets and a new upper plenum before putting the distributor in myself. When I got it back together it started right up great. The problem is that it now has a knock. Assuming it was a collapsed lifter from the backfire, I pulled it apart again to check it out. The lower end seems fine (knock is definitely coming from the top of the engine). I pulled all of the lifters & pushrods and they all seem fine (rolled smooth on a piece of glass). We’re assuming it probably has a bent valve in one of the heads (sounds like the driver’s side).

The original plan was to replace the head with a junkyard part and drive it again, but I just never got around to it. It’s very fixable, I, honestly, just don’t want to. We don’t really need the truck anymore and it’s just been taking up space for way too long now. At one time I had decided to part it out so there are a couple of items missing now. The A/C Compressor is gone (the rest of the A/C system is there and had no leaks). Also, the rear windshield wiper motor is gone (not that most of us ever use that anyways!). The tires have tread and hold air, but they are getting old. They’re useable for now, but probably only for another year or so. The interior is about what you’d expect, fairly clean, but obviously used. I’m a neat freak, so it was cleaned on a regular basis when I was using it, but I’m not the first owner. The rest of the body is in good shape. It’s not rusty and the windows are all good. All of the power options work. As a matter of fact, everything else works.
