Update on lemon?
So, here's whats happened so far. We had a mechanic take a look and he discovered that the water pump had ceased. This caused the timing belt to self destruct, taking the intake cam gear with it. He replaced the defective parts, set the timing ... and the engine still wouldn't start. In fact, it sounded as though the starter was running with no load at all. A compression check showed almost zero compression on ALL cylinders. He pulled the head and found NO damage to either valves or pistons. A check on the head it self showed that it was slightly warped, and there was a small crack between cylinders 2 and 3. He obtained another head, had it checked for valve seating (back pressure test on intake and exhaust valves exceeded 50psi), and ensured that there were no cracks or warps. When installed, there was NO CHANGE - the engine turns over, there is fuel reaching the cylinders, and a strong spark! Follow-up compression check showed 80psi on 1, less than 50psi on 2 and 3, and 90psi on 4. Chrysler tech assist told him that this engine needed at least 150psi on all cylinders before it would start. Thinking there might yet be a valve issue, he dismounted the cams and ran a sealed system compression test. Results: 58psi on 1, 140psi on 2, less than 50psi on 3 and 4.
We're totally stumped and have - to date - put over $1000 into this thing.
Does ANYONE have any ideas!
