If the timing belt tensioner has collapased the DO NOT drive the car until you get it fixed. Severe damage can occur. This keeps tension on the belt so it doesn't slip off and also keeps the valve timing right. If you drive it you risk the possibility of it falling off and the pistons hitting the valves.

There will be if the camshafts jumped timing. Check the marks on your camshaft and see if they are relatively close, usually if they are two teeth or more apart then engine damage has occured, however even if it jumped more there is still a chance that the engine was not damaged.

Can an engine rev when cambelt is taken off?


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.

The cambelt it just came lose and the car switch itself off,so i want to replece the tensioner and the combelt,it is nesessarly to replece the velve


It does depend on your engine design. Essentially if there is limited clearance (interference fit) between your piston head and valve then damage is likely otherwise you may be fortunate enough to replace the belt and be on your way. Important not to try to turn the engine over without at belt or the belt not installed correctly as this could cause damage.

Timing chain jumped two teeth on renault traffic


Reset the cambelt in position and tension, then do a compression test before wasting money on sorting a new cambelt
it maybe cheaper to get a replacement engine than rework the head.
please ask a more direct question if you need more info

On a 2001 mazda bravo turbo disel when do I have to change the timming belet it's done 176000 ks


Hi there,

Without knowing which diesel engine you have, I'll have to guess that you have a 2.5L (B2500) - Note: the more detailed information you give us, the more accurate our answers will be :-)

As a general rule, cambelts (with tensioner assembly & seals) have a limited life and should always be replaced every 100,000km, or sometimes earlier depending on manufacturer. The reasoning behind this is that most engines will suffer major internal damage if the cambelt snaps (this is what is meant by 'Interference' engines). As the engine has to be opened up to carry out this service, it can be a costly maintenance. For this reason, it is also common to replace the waterpump at the same time (to avoid having to open up the engine again) as waterpumps have been known to fail beyond 100,000km.

The good news....if you DO have a 2.5L (B2500) engine, then this engine is a NON interference engine - which means, if the cambelt did snap, your engine would not suffer any internal damage, compared to interference engines.

Hope this helps.....

1997 Mitsubishi spacewagon 2 ltr petrol, snapped cambelt, is the engine a "safe" engine and do i need to take out the engine to change belt and tensioners ?


Hi

These engines are not safe and I would bet you have some valve damage. you dont need to remove the engine to fit the belt however so if you want to try your luck then it might be worth a try. Mitsubishi's in my experience always damage something when the belt snaps.

Jetta TDI Coolant leak from behind tming belt.


hi from uk from the symptom/location you say water leak is coming from ? this is most likely to be the water pump that is leaking ? considering age/milage ? this is not uncommon however as the water pump is driven by cambelt this unfortunately means you will have to replace the cambelt and tensioner as well as the water pump it is policy never to use old belt/tensioner once disturbed for obvious reasons i'm sure you have heard stories of result of cambelt failure? and the serious damage caused to engine ? also if leak is serious? this will deteriate c/belt so advice you consider renewal asap cambeltkit +tensioner in uk casts approx under £45 and w/pump a little less you can obtain from most good motor factors/superstores avoid dealers this job is not too difficult diy with haynes or w/shop manual if you follow instructions and have tool kit hope this helps?

Timing belt went out on 1999 hyundai elantra


hi from uk the elantra engine is an interferance engine that means that should the cambelt fail whilst engine running there is most likely the valves will come into contact with pistons result will be bent valves whichmeans cyl head off and new valves/head gasket/ timing belt and tensioner consider this ? if your engine has high milage but ran ok prior to this failure ? it will be worth repairs as above however best to remove cyl head and inspect damage 1st ? if only damage to valves usually 3 or 4 renew them all and reseat new h/gasket etc you will get good result so all depends on investigation of damage ?

CAMBELT FAILURE ON A RENAULT MASTER DCI 120 2004 MODEL, IS THERE LIKELY TO BE ENGINE DAMAGE?


Definitely. If you're lucky then only the valves are damaged and that can be repaired by removing and overhauling the cylinder head. The water pump will and cambelt tensioners will also need to be replaced as they're relatively cheap and if they fail after repair the cambelt must be removed again. If you're unlucky then the piston crowns have been damaged or even the cylinder liners and this requires a complete engine rebuild. If only the valves are affected then the engine can usually be successfully repaired at a reasonable cost, but it's vital to get the head checked for cracks and flatness before reassembly as the stress on the combustion chambers and valve guides caused by a belt failure can warp or crack the head.

If time is money for you, then it may be cheaper to fit a good used engine. Note that there are no cheap "reconditioned" engines regardless of whatever worthless guarantees are offered. If you go for a reconditioned unit then if you're in the UK make sure that the engine supplier is a member of the Federation of Engine Remanufacturers (FER). Don't just rely on the logo on signs and stationery, actively check with the FER as some dodgy outfits have no qualms about claiming to ber members when they're not.

A good used engine will cost around £160 or so, make sure that you can hear the engine running before it's removed from the scrapped donor vehicle. It's cheap, but a risky choice and you'll need to add the cost of an immediate precautionary cambelt and water pump change.

A "reconditioned" engine means nothing. It might only have been degreased, repainted and had an oil and filter change. Recon is often a con.

A remanufactured engine will have been cleaned and then carefully tested before being largely or even completely dismantled. It's then rebuilt to precise tolerances using new or remanufactured parts. Expect to pay around half to two thirds of the cost of a brand new engine; they're not cheap but they are far cheaper than a new engine and will be supplied with a really worthwhile time/distance warranty.

I hope that you get your van fixed soon and that the damage isn't too serious. If my reply has helped then please return the favour by rating my answer.

1996 Mazda s/w 2.0 ltr M5 12 valve eng# GV10E - engine turns over floods readily won't start does have spark to plugs


Sounds like your timing is out, check your cambelt hasn't snapped first, if it looks ok look to see if the belt tensioner is ok and hasn't collapsed causing the belt to slip. also if the engine is spinning over really quick you'll want to do a compression test on each cylinder.
