Archived from groups: alt>autos>pontiac (more info?)

Hello,
I have a 3.8l engine in a 92 Transport and my wife has in her Bonneville 93
as well. 92 Transport has about 280,000 km and wondering if anyone could
share their experience with this type of engine with me.
For example,
1/ how long will the engine last (km)?
2/ what is the diff between series 1 to series 2 ( series 2 on newer 3.8L)
3/ can I upgrade series 1 to series 2?

Thx
MN

91 was a good engine. I've had extremely good luck with this car. I got
almost 267,000 on mine. Engine was opened up for the first time in 2002
@ 220,000 miles to replace the intakemanifold gasket. Put a fuel pump on
@ 250,000 for the hell of it. No oil leaks to speak of, doesn't burn
oil. I'm on water pump # 3, altenator # 3, starter # 2, Battery # 3,

Air Conditioner compressor still going strong. Transmission was rebuilt
@ 192,000 ( slipping ). The only sensors replaced were the camshaft.
IAC, and Oxygen sensor. Fuel injectors, radiator, heater core, EGR
valve, belt tensioner, TPS, MAP & Crank sensor are original. Oil /
Filter / Grease every 3000 miles. Never been towed, never been a day
where it hasn't started. No starting problems or runnabilty problems.
The rear wheel bearing hub assemblies need to be replace though, they
are starting to make noise.

1992 I think was an EGR less engine, then the EGR was replaced agian in
1993.
The 95 - 3800 came out with a two piece intake manifold, Upper part is
plastic lower portion is aluminum. The plastic tended to warp or crack
causing antifreeze to leak. Some modifications were made to the plastic
intake around 1999 2000. But the engine is still plagued by intake
manifold gasket failures. Other than that the engine is a good runner
and gets good mileage. Mileage rating on the 2004 Impala LS is 20/30.
The 2003 was 19/29.

Good Luck

The 3800 is a very strong, very reliable powerplant. Personal experiences
have seen 3800s running beyond the 300,000km mark with no problems.

Difference between SeriesII and SeriesI is to do with manifolds and tuning I
think... check with some of the more experienced here. HP is better with the
SeriesII.

Bolt pattern on the SeriesII is same as SeriesI as far as I know, so a swap
is possible, but I don't think you can 'upgrade' the SeriesI to SeriesII
spec easily.

In summary the 3800 is a great engine and don't give hassle if maintained -
with exception to likes of the intake issue of the SeriesII...

Its much deaper than that. Not only is the intake diff but so are the
heads. The design difference is to great to even bother attempting to
swap in the 3800 seriesII into an older application. You can use the
shortblock of the newer 3800 in an older car however but dont bother
getting in any deaper than that or its not worth the time effort in the
end.

The Series II & Series I engines ARE NOT DIRECTLY SWAPABLE!
They use different: Intakes, Heads, Exhaust Manifolds, Cams, Cranks, Conn
Rods, Pistons, etc.....
The Block is about the ONLY thing they have in common.
Now with that said, you can still swap in a Series II for a dead Series I,
but you've got alot work ahead of you too. The entire engine bay wiring
harness has to be changed too, plus you have to add in a PCM (Power Control
Module), that is needed by the Series II & not required for the Series I.

Thanks for the information. Both of our cars are still running strong. I am
glad to hear that 3800 is a good engine.

Thanks again!

Are you thinking about the bolt pattern to the trans?
Because there are huge differences between the
GENI and II blocks other then the bolt pattern.
Bolt pattern is the same, but the GENII has
cross bolted mains, a separate aluminum
housing for the rear main...etc, etc.
