From my experience in cars, they are pretty cheap because they are
crap,
or next to it.

I have heard that enough times to wonder it there might be some basis;
OTOH, back when they were still current production, my local Chrysler
dealer
believed they were sufficiently reliable that a 100,000 standard factory
waranty was imminent.

I don't recall whether they were bimetal or aluminum block engines, but
adiquate and consistent cooling is *very* important with aluminum heads
on
an iron block.

Also, some of the newer designs may be lighter, although I don't know
the
weight of either.

BTW, Ford had a 3.0L and GM had a similar engine that may have been the
3.4L, which were both just about as compact as the Chrysler 3.0L and
3.3L
engines.

The 3.0L Chrysler engine of recent times is not a push rod engine. It
was a Mitsubishi design and had its share of problems, particularly
with valve guides and cam and crank seals. The 3.3L pushrod engine
(and its variants) is of US design and manufacture.
Search rec.autos.makers.chrysler.

Now that you mention it, I recall that the 3.0L was a Mitsubishi design, and
that the complaints that I heard were about it. Apparently, the 3.3L was
not a revision of the same engine, as I had supposed.

A quick look in the rec.autos.makers.chrysler group strongly suggests that
the 2.7L might also be a poor choice. It's obvoisly hard to guess how much
is simply poor maintenance, but an Intrepid is obviously a much lighter load
for an engine than an airplane...

Peter

The 2.7 isn't part of the 3.3 family either and IT had its own
problems, many of which could be ameliorated by rigid maintenance.

I don't understand your specific reference to the "load" in an
Intrepid being the measure of suitability for the engine's application
in an airplane. The jump to aircraft use for any auto engine is a big
one no matter what vehicle it comes out of.
