Harmonic Balancer goi
1998 Cherokee 4.0 215,000 miles. Is my Harmonic Balancer going/gone bad? Put in new driver side Motor mount, there is no dead cylinder, the vibration starts as a rhythmic pulse from idle, then at 2500 its just a full shake. Does not matter if Transmission is in P, N, or D, under load or not, MPH is also not a factor. The only code i have is EVAP related, P0455. There is also a good amount of oil leaking from the front of the pan. I think it may be one of three possibilities: 1 Harmonic balancer 2 Torque converter 3 Internal rotating assembly. What are your thoughts?

That would be a rare exception. I am interested to know what could cause that condition. Have you fixed something like that?
A v8 (or more) could possibly hide the lope. I have had a few I6s, Supras and this Jeep, and I felt a missing cylinder every time. It quite sucks, actually, cus it usually means $. lol :/
FWIW, I have been experiencing a missing cylinder on my Jeep, but only when the engine is cold. If I bring it to a fast idle of 2k, it clears up and doesn't come back until it sits overnight again. I am pretty sure it is a 'sticky' fuel injector, but I don't have the cash to replace them just yet.
