My bad about the reliefs. I did some thinking on that one and edited my post.

its the other way around, they are not freewheeling engines. if the timing belt, u usually bend valves.

yes but when the timing belt snaps the valves close. if the pison is moving fast enough then yeah it will bend some valves but say it snapped while driving like 2000rpm then you may not bend any valves

that was my thought on it. all i know is ive personally never checked the valves of any of the cars that ive had snap belts and ive thrown a new belt on and car ran like before. and numerous times have i read it done like that on the forums

for sure you can get lucky some times. It depends on the driving situation, and a little bit of luck. But I bet you v8killaz, that on some of those engines that you just slapped a belt on and it ran. That some valves were bent, however slightly but still had enough compression to run.

Sometimes they bend valves, sometimes not even on an interference engine.

I would replace the belt as it is a lot less work and cost than pulling the head. If it fails leak down or compression tests, then pull the head.

Even a non interference engine might have had a cam change or some machine work done or piston replacement that changes it to interference.

If it broke at 25,000 kms or even 25,000 miles (you don't actually say which), it could be a bad bearing in any of the water pump, belt tensioner, distributor or camshaft or oil starvation to the cam or a bent cam or some FOD between the belt and pulley.

ya i totally agree thats why i said usually. sometimes it does, sometimes it doesnt. always do a compression test afterwards before placing like pat said.

Quick question, do I have to pull the harmonic balancer off to "Put" and timing belt on?

And also, when my belt snapped, wat was the reasoning of the "oil light" an the "battery" light coming on?

Yes, but once you remove the bolt, it usually just slides off as it is not a press fit.

That oil light and battery light came on because one the belt snapped, the engine stopped turning assuming you either have an auto or were in neutral or had the clutch disengaged.

Yes.

Oil light will come on because when your engine isn't running it isn't pumping any oil, so the sensor isn't seeing any pressure. Same thing with alternator and battery light.... I think. low voltage or what not. I like oil not electricity.

Wow!, I read, "timing belt snapped", and I felt like I was at a funeral.
Looks like you have some options to review..

There are countless threads on how to get the crank bolt undone. That is the hard part. After that the rest is easy.

Careful you do not loose the tiny crank pulley key. They are often dislodged from both the groove in the crank snout and the groove in the pulley and fall to the ground never to be seen again.

I like this forum a lot... Thanks for all your help everyone..
I can take the right side motor mount off without the engine falling correct?

Just get a piece of 2x4 or something and put a jack under your oil pan. Just for support. The emergency jack works well. Put the wood in between the jack and the oil pan

We like this forum too lol. If I were you, I would take a piece of wood and put it between my jack and oil pan so as to not dent the pan when you are supporting it just in case it decides it wants to take a hone dive.

edit: mother fucker..... ppl been beating my to the punch all week

i was made to understand that an interference motor is made to deal with a timing belt snapping so that it wouldn't bend valves and things of the such. unless of course the motor was modified and cam timing was played with.

edit: I retract this statement and I'm an idiot. that is all.
