Use a leak-down tester in the suspect cylinder to see if the valve is sealing.
You can do a cylinder leakage test to check for bent valves.You can do a cylinder leakage test to check for bent valves.
do a compression check on each cyl.
Check engine light, low power, no start, runs rough, bent valves,Check engine light, low power, no start, runs rough, bent valves,
If you are worried about bent valves DON'T That year engine will not bend the valves when the timing chain goes bad.
Replace the bent valves with new ones. Several places carry them. Be prepared it is a very in depth job. Be sure to check the pistons to make sure they aren't too damaged from the valves coming into contact with them.
Yes it is. I know this by experience. Timing jumped and bent the valves
Bent valvesBent valves
Remove the spark plugs and check the compression in the cylinders, low to no compression will indicate a bent or stuck valve
Timing marks are not lined up correctly.
One of the most common reasons for bent valves is a broken timing chain or belt.
The main cause for bent valves is a failure in the timing chain or belt. When the valves and pistons are not exactly in sync, they can collide.
If the valves bent, then yes.
