i think you are going to find that your valves are bent and you will have no compression. removing the head and getting a complete valve job is most likely in your future. in a fight between the top of the piston and the bottom of the valve the piston wins.
I assume the timing belt broke or the cam gears jumped a couple teeth,before your repair shop did all the recent work
So yes, the valves could have gotten bent
The repair shop should have checked that, or they didn't time the new belt correctly ( It could happen) and they caused the issue.
When I read your question again--I think they caused it,you can't prove it though.
You do a cylinder leak down test,not a compression test
60,000 Miles also your van is an interference engine which means if timing belt breaks will cause major engine damage ( bent cylinder head valves ) and cylinder heads will have to be remove to replace bent valves.
It may help to tell what engine you have???? what 2 notches are you referring to? Engine damage can result if the timing belt broke like that (bent valves) Why did it need a crank sensor? thats a strange coincidence.
Hi there what you need to do is a cylinder leak down test. the way to do this is get the cylinder you want to test to top dead centre (top of its stroke and remove the rocker cover and get the respective cylinder so the valves are closed. then put air pressure into the cylinder and you will be able to hear if the valves are leaking back through either exhaust or inlet. It is highly possible that you have bent valves with that engine but you could be very lucky. GOODLUCK
Hi,
This is probably one of the worst things that can happen.
If it only jumped by a few teeth, then two of the pistons would have come up and found valves in the way. At this point, a couple of things normally happen. -
1 the engine siezes solid as there is nowhere for the valves to go.
2 The valves get bent, and the piston heads damaged.
3 The camshaft is stressed, and rockers can shear off as the valves are pushed back.
It usually results in damage to - Cylinder head, 2 cylinders (at least) - All damaged valves need replacing. Camshaft and rockers need crack-detecting, and/or replacing.
Most of the damage is restricted to the head, which needs taking off. It may be more cost effective at this point to replace the entire head from another scrapped vehicle than replacing parts individually - as you may miss small cracks, but this is a judgement call for cost vs time.
