Just got a 1990 Dodge with the 3.0 in it. Any known problems with these?

No. The 3.0 V6 used on every other Chrysler product was a Mitsubishi-made engine. The Dodge Monaco/Eagle Premier engine is the P-R-V V6 engine, so named because it was designed and built as a joint venture among Peugeot, Renault and Volvo. Versions of this engine were also used in '76-'85 Volvos and in the Delorean, among other cars. The engine itself, in the

3-litre form you've got, is not terribly problematic though parts are expensive. You've got much bigger worries with the engine management system and vehicle electrical system. And the transmission.

OMG are they still around???? run>>>>>>>>>

Mitsubishi-made

That's pretty much what I have read in this NG over the years about these cars. The styling was nice, but the electrical system was prone to failures.

If I remember correctly, when Chrysler aquired AMC/Jeep in 1989, they were required to continue to produce these cars under the terms of the purchase agreement. Renault had just finished a manufacturing plant, and they wanted to try to recoup their investment.

The biggest problem is excessive oil consumption. Ususally caused by bad valve guides, valve guides partially dropped out of the head, or piston ring problems.

100% true.

Not usually. They're one of those "cockroach" engines like the GM

2.8/3.1/3.4 series- they run forever but have no other redeeming features whatsoever, and you start finding yourself WISHING it'd puke a rod out the side (which the GM ones actually do not too infrequently....)

Watch for oil consumption. There are MANY tech service bulletins on that engine for oil consumption throughout its entire production run, and they never did get them all completely fixed. The worst problem was the valve guides slipping down in the head and creating 24 large oil leaks. the fix involves getting at the top end and (IIRC) installing a snap ring on each valve guide to keep it from dropping out. Don't remember if you had to pull the head and machine anything or not.

Disregard my previous post- For some reason I saw "Monaco" and read "Dynasty" instead.

Dan's right, its not a Mitsubishi.
