Why is my Jeep running so bad!

You know how many Chrysler 3.0 Litre Mini-Van's I have heard pull up to the lights beside me that sound somewhat like that.

I motion to the driver to put down their window and tell them they have no oil or need oil and they thank me and drive off.

Those 4.0's are pretty stout engines.

my 2.5 sounds like that when I use Fram oil filters and a cold start lol.

wow, the 4.0 is one of the toughest motors out there, wonder what they did to cause that?

That poor engine. It's staving.

A con-rod sticking out of an engine -- a useful clue that something may be amiss. . .

(I'm sorry -- I just couldn't resist). Best of luck with that mess.

It's not my engine!

Lucky you...

That sounded like a cracked exhaust manifold ...which is quite common for the 4.0 at least through 99. In '00 they went to a two piece manifold with precats.

Yeah, it would be very rare to see a 4.0 have issues like that.
