Except for one critical part. The timing gear. I'm sorry, but teflon
and plastic gear isn't my idea of proper. The camshaft button on them
is also teflon, so when it wears down, the spring on it grinds a hole in
the timing cover. Turns out this needs to be replaced as often as a typical
belt - or done once with metal replacement parts.
I've *never* had this problem, on any of my 3800s. When did GM go to metal?
I've used a 87 model, and two 89 models (one which I still use), as I posted
before, all with at least over 165,000 Miles (One was over 200,000), and
never replaced any timing components... My current Park Ave (89) has had
50,000 of fairly hard driving in the past year or so, and, as I said, the
worst that I've had to do was an O2 sensor, and the front motor mount is due
to be changed. (I'm not including oil changes, brakes, spark plugs/wires, or
the like, which I consider maintence items, not repairs.)
Actually there is more than that.....
3.8-3 Original (86-91)
3.8-C Original (86-91)
3.8-L Series I NA (92-94)
3.8-1 Series I SC (92-95)
3.8-K Series II NA (95-03)
3.8-1 Series II SC (96-03)
3.8 Series III (04+)
These are just the FWD versions too.

Pardon me for what may be a ridiculous question, but what is the difference
engine-wise between FWD and RWD? Isn't one just turned sideways from the
other? So maybe the mounting points are different. But wouldn't all the
differences be in the transmission vs. transaxle?
Theres more to it than that. The intake facing the other direction is
one of them. When F-bodies started using 3800's Series II engines they
used a aluminum plenum facing the front of the engine. All the FWD cars
used plastic plenum facing the rear of the engine. Coolant routing,
exhaust routing, and a number of other things would be different as
well. The block on the fwd versions dont have a bolt hole where the
transmission mounts tapped out because its not needed. The rwd versions
would have it tapped. If you ever see a 3800 shortblock thats one way of
telling them apart.
