Cambelt broke on start up - Cars & Trucks

That is a interference engine. I'm afraid your vales are now bent. The head must come off.

Hi Tino, The links below are YouTube videos showing how to fix a car that doesn't start/cranks but doesn't start, Also there's videos down the right side of the links that may help as well....................CHEERS..

Fixing Car That Cranks But Doesn Start Up

Car Cranks But Will Not Start

Hi

To answer your question directly......NO, the engine can not rev when the cambelt is removed, it won't even start. This is virtually impossible for any 4 stroke engine.

i will explain why....... The cambelt connects your camshaft with your crankshaft, when the engine was assembled, the camshaft and crankshaft was turned on the correct alignment marks and the cambelt was fitted. These marks on the cam and crankshaft allows the 4 strokes to happen at the correct time(intake stroke,compression stroke, power stroke and exhaust stroke) If the cambelt had to be removed, there will be serious damage done to your engine, in the first place, the car will not start if the cambelt was removed. the correlation between your camshaft and crankshaft will not correspond and the pistons will hit and damage the valves.

I hope the above description will help you.

There should be marks on the cambelt itself that align with the gogs markings. Best to start at Top Dead Centre (TDC) If the belt has broken then if that has not done damage to the valves I'd be surprised. If it is a turbo then the valves do touch pistons when out of sync. I have no knowledge about non turbo cars but I think the engine configuration is similar . To be honest it is best to get someone who is familiar with the cars to do it. Especially if it is a turbo. It is one car that requires knowledge and experience to do this particular job. The Cambelt is very long , goes over 4 camshafts , water pump plus guides and crank pully ect. That all needs precise alignment. No errors are acceptable so it is up to you. Think about it and read up before you do it.

Yes. I think. A lot of cars have the water pump under the timing cover and you change the pump when you change the timing belt. They usually don't seize though, they just leak. Did you run it after it broke? How long before the engine quit? Did it start knocking? When you go to change the belt, look for a broken cam, or other damage that the broken belt would have caused. Some engines are free running, meaning they will turn over no problem when the belt goes, other engines are intermittent, meaning the valves hit the tops of the pistons and cause considerable damage. Find out before you go too far. Hope this helps.

Sorry to say there is most likely quite expensive damage to the valve train and pistons. A new cam belt can be installed and the motor rotated to see if it is turning freely after which you would do a compression check (lack of compression will indicate bent or broken valves). I've never seen a diesel break a belt and avoid damage, virtually always a catastrophic failure.

If there is a serious problem, the the cylinder head will have to be repaired.

try looking on www.gates.com hopefully you can find all the specs as well as a replacement belt for purchase, hope this helps, let me know
