busted timing belt
 

what can happen to an engine when the timing belt breaks? I know that valves can be bent, but can anything happen to the block?
I am wondering b/c i am trying to find a b18a/b for a lsvtec. I found a 93 b18 for $350 but the timing belt is busted. Say the piston did hit the valves, would that cause any damage to the rods, crank, cylander walls, block?

heh...my timing belt just blew on my EF. Not sure what else can happen.

Normally when that happens the valves get damaged and bent. There can also be some damage to the surface of the piston that has hit the valves. But block, rods and crank are pretty tough. They should survive easily.

is the motor in the car? how do you know somedidnt break it after it was out of the car?

I've had the timing belt loose a tooth and stop working. when that happened there was no damage to the motor whatsoever it just wouldn't run

so u guys think that its safe to buy a used engine that had the timing belt break if i am just using the bottom end?

for $500, you could get a complete b18b, but if you are rebuilding for ls/vtec im sure that block will be ok, usually its the valves, like everyone has mentioned.

where can i get a b18b for $500? At Mike's in Hamilton its $700. Dominion for a 91 b18a its $500. I've called almost ALL of the local junkyards around hamilton and not too many places even have this engine.

why go to the wreckers, i just picked up a 2000 b20b engine for $750, they had b18b's for $500, 550, b16a (obd0) for $650, etc....JK japanese 401&kipling.

JK japanese 401&kipling huh. Thanks I'll give them a try. But i would prefer to stay around hamilton b/c transporting the engine long distances may be a problem.

401&kipling? wtf I live in this area my whole life and never heard of these people. lol
