Problem Found! Aux Belt Sort Of Gone Help?

[Bondie]

Right basically looking to see if this has happened to anyone and ask for some advise!

The Aux belt has frayed and a strand off the belt has come away, now at the time the car cut out straight away and the STOP light came on, NO engine warning light atall, since then it will not start theirs spark from all 4 cylinders and fuel getting throught. Ive been told that it has probley wrapped itself around the crankshaft and knocked the timming of the engine out.

The cambelt itself is still intact and has not snapped, it was only changed 20k ago but no sign of the aux belt being done at the same time. Also when you try to start the car the cams still move so thats a good sign right??

Now the car is booked in to be inspected tuesday but do you think their will be valve damage? I can get hold of a newish skimmed head if needs be for £100 if they have but whats my chances??

Cheers Bondie

My guess is as good as everyone elses with regards to the valve damage, Unfortunatly theres no definitive answer.

The cams moving is a good sign shows the belts not snapped but it doesnt mean it hasnt jumped a couple of teeth.

Have you removed the aux belt and tried to start it?

 

[Bondie]

No i was going to leave that to that garage to sort out, but if their is valve damage i have got a head lined up to replace it.

99% There will be valve damage.

^good effort!

see why i bang on about having a full aux kit fitted rather than just a belt!

Prevention is better than cure Fred!

So is that what has happened to my valves then isit? will the cam still move if the valves were like that?

cheers

Now booked in for a full cambelt and aux change using renault parts for £400. if theirs is valve damaged probley not to all 16 as the engine cut out straight away i will be able to replace them all between myself and cookie jnr. So maybe not the end of it yet!

The cams will still move because the cambelt is still on all the pulleys. Its just jumped out of sync. You will find you can move the pulleys VERY freely with the cambelt off. This indicates damage. Also you will probably find the tappet rollers have all been smashed off.

Compression test would probably be the easiest way to confirm without having the timing tools and without major surgury but i'd imagine the above has happened as said unfortunately.

 

[Bondie]

Will a compression test tell me if the valves have bent?

 

[Sean6545]

Yes

 

[Bondie]

Okay but does the car need to be running to do a test???

 

[Fred@BTM]

no, just needs to be able to crank over

No you just need to be able to crank it over

Edit: got to the tab a bit late lol
