Run a compression test to make sure, I have one that only bent one cylinder's worth and it runs on 3. Did one last year and it bent the exhausts on one cylinder and the intakes on another it wouldn't run. The timing belt and water pump should be replaced at around 80 to 100K. It also is a good idea th replace the cam seal or seals if it is a DOHC. Dodge has a seal retainer that bolts behind the plastic cover to keep the seal from poping out. This is a big problem with the 2.0 dodge engine if it does there is a bad oil leak and more than one has bit the dust from running out of oil.
