Well, I'm now the owner of another Jeep CRD, but this one was bought DOA as a Spring/Summer project car. :dizzy:

P.O. says car was traveling down the highway and started losing power and eventually stopped and wouldn't start again. Took it to a repair shop and they told him the motor wasn't turning over and needed a new motor.

Guy spent LOTS of money in maintenance and upgrades but it looks like after 130K miles there's no evidence of timing belt change :oops: or fuel lift pump, but there is an inline thermostat :shock: and a receipt for a GDE hot tune. :BANANA:

This one won't be solved in the next week or two so you've got time to think about your cause of death explanation. :dead:

Now the only thing is to figure out how much time/money to put into this thing if I'm going to flip it.... :5SHOTS:

Does the motor turn over?

The EXTREMELY limited information you've given, I'm wondering if the inline thermostat somehow resulted in localized overheating in the cylinder head. Not saying that's what it is, but I'd put it down as a possible contributor.

Best off the wall worst case scenario guess without more information; A dropped exhaust valve! :grim:

Based on that description, my guess is cracked head that quickly started releasing coolant into a (or multiple) cylinder causing a loss of power and eventual hydrolock of the motor. Doesn't say if anyone has removed a glow plug or injector to check for coolant yet...so that's my guess!

I'm with WW. We've seen this episode before. I'm guessing that the reason we see dropped valves on the highway is that they have time to heat up, and there is a relatively high amount of force applied to the valve from highway speed rpm's. But I'm no expert on broken valves

A couple more things:

PO said there were no unusual noises during the power loss, and he even thought it might just be an electrical problem

Engine could not be turned over by hand at the repair shop after the incident, and they told the PO they scoped the cylinders but didn't see anything unusual, but they may have only been looking through glowplug holes.

Question: Would a dropped valve 'go quietly into that good night' or would it make a big racket?

A dropped valve would not be quiet and would quickly bring the engine to a halt.

If the motor really wont turn over, then the only thing I can think of is a seized bearing on the crank. Without evidence of an obvious failure in one of the cylinders and no noise or "bang" then what else can it be?

Can the transmission and torque converter fail in a locked state, preventing the motor from turning and also simultaneously bog the motor down until it stalls? Quite a long shot there...
