timing belt help

4twenty · #1 06-27-2006, 02:29 PM

ok so my timing belt snapped on the highway doing 130km, i'm finally getting around to putting another one on now and i still havent checked the internals... what's the worst that can happen if i just slap on a new one and fire her up??

well nothing bad will happen if you "slap" a new belt on. what could possile happen to the internals is it could have bent a valve or like me it could have cause a hair line fracture in the valve and then overtime with heating and cooling make the valve break a chunk off.

Take the head off and check everything out. People break things from going less than half that speed when they have they t-belt snap.

People can break things not even moving..

so if i put on a new belt and start the car, the engine wont get any more fucked up? and will it run with bent valves?

I would inspect the inside before you start it back up...it will only make things worse for ya (if ya start it up b4 checkin it out)!

Yeah, who knows how much damage (if any) there is to the head or pistons..

Everyone here has told you to do the opposite of what you just asked. It's for your benefit that you check things out before just doing it and hoping everything will be ok.

alright, next question - how come the crank pulley is so hard to pull off, is there a special way?

A puller...

It's a tool

First just take your head off and inspect it. Dont even waste your time and money on a new belt if your head and maybe pistons are fucked. The worst that can happen when putting on a new belt and starting her up is you would hear a bunch of broken shit in your engine and the valves would all snap and you would cause a bunch of internal damage...this is all assuming you time it properly. If you mess up the timing, it'll probably be worse. IMO dont waste money on a new belt before taking off your head and checking for damage. If you did mess up valves or pistons or whatever, just get a new block or swap a whole new motor..my 2 cents

I'd say the opposite. Think about it logically. What's your goal at hand? What's the easiest way to figure it out?

1. You can spend $30 on a new timing belt and put it on. Try to start the car. If it doesn't start...oh well you just wasted a whopping $30.

2. You can pull off the head. Send the head to a machine shop to see if the valves are bent (rarely can you see bent valves w/ the naked eye). you'll have to buy new oil, coolant, head gasket, intake gasket, etc....which will cost you more than the price of just a belt. And you'll actually STILL have to buy a belt anyway.

just put the new belt on, see if it starts. If not, you need a new motor.

i agree you seem like the guy that wouldent care to put the timing belt back on then starting it up. well hopfully anyway. just do it and see. make sure you get the timing right
