Re: Engine Replacement Questions - 92 Lumina 3.1

My brother has a 92 Lumina, and the engine's got multiple problems. It
blew a headgasket, and warped a head, and we were given a quote of $800
to fix it. The car has 240,000 KM on it, and the body and chassis are
quite good. It's a 3.1 V6.
Just a few questions-
Is it pretty straight forward to remove and replace the engine in the
car - from above, or does the frame have to be dropped to do it? I've
done a few engine changes - Dodge K-cars, others...
Lumina 'car'....right? Not the van? If it's the car, the engine comes
out the top...no need to drop the chassis. Pretty easy engine r and r as
GM vehicles go.
Will the 2.8 MPFI (87-newer) fit in, or does it have to be a 3.1 from a
'92? There are a few low-km engines for sale locally for $200 or so...I
think I read something about the digital EGR causing problems.
If I were you, I would attempt to get the same year engine, from the
same type of vehicle. If you are getting a used engine, the wrecking
yard often has the means to figure out what engines from what vehicles
will work. But....be prepared to switch over a number of items. Plus, if
your original engine was running good before the head gasket went....I'd
use all the fuel injection gear from the old engine and all the wires,
coil packs, sensors...etc from the old engine.
What is wrong with the block you have?
Low on compression,oil seeping past your rings?
Not telling you to not change out your engine...But why if its just a
And then to goto a smaller engine?Ian is correct about the digital
egr...Also if you downgrade to a smaller engine I think you need to
change out your PCM because everything will be out of range.....But dont
quote me on that....
