TRUE,
long with my "new" 05 sebring convertable I still keep my 89 olds
ciera 210k miles for the weekday work trip, I junked the 86 aries in
05 and got the sebring in it's place
American Cars are the BEST
Then, howcome I have a 1985 Corolla GTS in the yard with 258,000 miles that
still starts on the first turn of the key, and just gave away an '85 Celica
in excellent running condition that still starts on the first turn of the
key, but my '92 Grand Voyager sounds like it's going to BLOW UP any minute
now, and it only has 127,000 miles on it?

To start with, we motor room mechanics were a little disappointed when [the
engineer] came down with the first prototype parts for the 3.3. We were
expecting an overhead cam-high tech-high performance engine, and were
shocked when we pulled out a bag containing push rods!
Somebody had done a survey of potential customers and decided that the
customer was too dumb to know what was under the hood anyway, so the "cost
effective" approach was taken. Ford's Taurus engines and GM's 3.8 used
pushrods, so why not us?
We were paying a high premium for Mitsubishi's 3.0L V6, and Trenton Engine
had room for another assembly line, so it was a no brainer as far as the
necessity and where it would be built. We had some problems early on with
valve stem finish which was quickly fixed, a bigger problem was thrust
bearing failure. We were getting some engines coming in to tear down with
incredible end play, you didn't need a dial micrometer to know which ones
were bad. Our manager grabbed me and 3 other mechanics and we spent the next
2 days at Detroit Metro Airport checking crank end play on Snappy rental
cars with the 3.3 engine. Most were okay, but an occasional one would
produce not 3 or 4 or 5 thousandths end play, but 100+ ! The blame was aimed
at the transmission, but we immediately went to a wider thrust face. Has not
been a problem since. [Note that the 3.3 was produced for many years, and
these early problems affected only a relatively small number of engines.]
I had a real battle with an engineer in regards to the head bolt washers and
the ensuing CYI approach he took to, well, cover his behind. The 2.2 and 3.3
used the same head bolts and washers; a decision was made to widen the head
bolt washer to increase the clamping area. Only problem with this was that
on the 3.3, the wider washer could hit the valve spring that is next to the
oil feed cam tower. And they did.
[One engineer] told me that noisy tappet replacement was our fifth biggest
warranty item on the 3.3, but when they got the suspect parts back to
engineering, they weren't noisy. I fought to get a service bulletin written
on this, to check for interference before doing a costly cam/tappet
replacement, but another engineer [tried to cover up with] the claim that it
"helped attenuate" engine noise. On a visit to Trenton Engine, I found the
line worker who assembled the heads and asked him why he didn't notify
engineering about this. "I did, but was told not to worry about it," he
replied...
Another problem is oil leaks. Anytime you bolt aluminum to iron, the gasket
in between is compromised, due to the expansion differences between the two
metals. This is particularly evident in the chain case module gasket. The
gasket moves over time and creates a gap just above the oil pan rail, and
boy does it make a mess. Lower intake gaskets leak in the corners. An
upgraded gasket was designed with longer, tapered rubber ends that was
supposed to end the use of RTV, but RTV will always be a necessity on that
application.

rockers and the oiling system. I did not know when it was corrected...
Apparently they fixed this by the second year of production.
: The 3.5 had a rather interesting intake setup. There
were two separate intake manifolds for the left and right side cylinders
with their own throttle-bodies (interesting throttle linkage and cabling
there). So in a way it was like two in-line 3-cylinders that were joined at
the crank.

engines ever to come off the line. The pulleys on the (at least the early)
3.3 are made out of plastic, they break easily. The power steering pulley I
have replaced 4 times in the past 4 years."
Yup, American cars are the BEST, ok...
