I have the 1992 Oldsmobile Silhouette (ya- the ugly nose minivan). It has
165K now and runs like a horse, exactly like the day i bought it! I admit
that it does have lots of 'body problems' (like windows- AC and other little
American car annoyances).
All i know is that it is a 6 cylinder 3.8 engine ( or is it 3.1?). My
mechanic said that it is a great engine and is in some BUICK cars.
I want to purchase another vehicle that has the same engine and
transmission. I would prefer to buy an SUV.
Does anyone know what is this engine and which other GM SUV has the
From '90 to '95. Olds Silhouettes (and Chevy Lumina APV and Pontiac Tran
Sports) had either 3.1 or 3.8 V6's. The 3.1 is an iron block engine with
an aluminum head, and the 3.8 is iron on iron. The 3.8 is the more durable
and better engine, and since your mechanic praised your engine, you must
have the 3.8. Starting in '96 and continuing today, the GM minivans
started coming with the 3.4 V6's only with no other engine available. GM
should have put the 3.8 in it. As to your question, the 3.8 has been put
into a lot of GM cars since the mid 80's and is still used today. You'll
find them in base Firebirds, Camaros, and in Buick Park
Avenues/Regals/Rivieras, Olds 88/Toronados, Pontiac Bonneville, Chevrolet
Impala (even used for police cars), etc.. Some of these cars even have a
supercharged 3.8. My favorite application would have to be in the '88 to
mid '90's Buick Regals. Regals are real nice.
Must be the 3.8 if you love it so much :). The 3.1/.4 family does not seem
to be as robust as the all iron 3.8.
The 3.8 is used in many current GM cars, but not in any of the vans, trucks
or SUVs as far as I am aware.
You can see some of the current applications of the 3.8 at:
The supercharged version listings are at:
I think that the 3.8 is also an option on the Impala, even though not listed
