Does timing jump cause engine replacement? ===========================================
My TOYOTA Camry 1999 was driving OK. I do check under the hood on and off, I did not do that check for awhile. Last week my car started OK. Within two(2) minute driving RPM started decreasing and lost power. The car engine cut-off. It crank the engine as I turned ignition, but it did not start. I towed the car home. I towed the car to auto service shop. My mechanic is telling that my timing belt was jumped and hit water pump. He did leak test and find leakage in middle 2 cylinders. He wanted to replace the motor.
I did not drive on high speed and drove 2 minutes from starting. My car has non-interference engine, so it had timing belt instead of timing chain.
Does this situation cause such engine damage?
Is there a way to fix leakage in middle 2 cylinders as alternate to motor replacement?
If yes, what is it called?
Does any mechanic able to do that?
I have auto transmission. Did switching to neutral in this situation help?
Thanks for your insights.
Thanks for your replies/suggestions (insights).
My car has less than 100K miles on odometer. Timing belt did not break in my car. It jumped off the pulley & hit water pump. Did such event impact/damage cylinders?
He removed upper timing cover, front passenger wheel and rotated the camshaft manually to do leak down test .
He performed the leak down test using Cylinder Leak-Down Tester as shown in http://www.harborfreight.com/cylinde...ter-94190.html.
It showed the following reading.
Outer two Cylinders 0 - 10 % (Close to Green)
Inner two Cylinders 100 - 80 % (Red)
Did anyone one work on such situation?
I shared your thoughts. He was upset that I did not trust his judgement. He is not liking to challenge his experience. My mechanic is saying. The reason for leak in two cylinders is , piston hit the valve while my belt jumped. It caused this damage.
Does it make sense?
