To Terminator and Doug:
If you are wanting to keep the cars, maybe you should check out this
This place fixes all the bad things that were wrong with those engines
when they rebuild them. For $1400 you can replace the 4100 engine, and
for another $100 you can get a 4500 engine. You can even send them your
old one and they will fix and rebuild it.....may save some money that
way, but not sure.
Anyway, it can't hurt to check them out....
