89 codolla all trac wagon, if the t-belt goes, does that bend the valves?

use timing belt , if has 8valves dont bend , if has 16 valve ,bend valves

YES, if the timing belt snaps and the engine is still rotating, yes the valves bends.

It's an inteference engine.... If the belt goes and the engines looses timing, the valves bends.

In my book--- toyota corolla 1984-1993 , if the belt fails then the valves will be bent

firing order 1342 timing belt alaing the mak on the gears to the block

need 2 know more specs it is a timming belt or chain depending on year and model if cam is not working valves wont move most likley broken chain or belt some models will bend valves when it goes let me know thanks gordon

Yes, on any vehicle if it is in motion when the belt goes out the wheels continue to be engaged and turn the crankshaft of the motor, moving the pistons up and down. If the valves are open... and they are, then as the piston reaches the top of the cylinder it will strike the valve and bend it and the rod. It will also scar the piston top. Dependent on the damage to the valve and rod a valve job may repair the issue. More often than not if the piston and valve made significant impact the whole motor will need to be rebuilt to insure the crankshaft wasnt damaged, piston punctured, or block cracked.

check vacume lines on my 89 jeep cherokee i had to be rolling a little to switch it in and out

You got the ignition cover, what you need to do an cylinder compression test and also check your injector for voltage while engine running hook test light to battery pos on neg and neg on pos, at injector harness check for pulsation, if you have pulsation elec. system ok, if good compression bad injector.if bad compression piston ring's or valve's.

loosen appropriate pulley tensioner by loosening the nut in the centre of the correct pulley,back off tensioner and pulley will loosen on belt,change belt and do the opposite

yes they bend valves
head needs to come off and valves will need replacing
this can be repaired
timming belts on these should be replaced every 60,000km
