cambelt snapped



  Polo + Micra
how much is it roughly going to cost to repair it?

or is it going to be a better choice just to stick a new engine in it?

you might just be lucky with bent valves, need to rip the head off it to find out.

Specialist Breakers do used engines at a good price.

Might need a couple of pistons too if they've been twatted, a re-hone if the valve split, the list is endless mate. You'd need to take the head off and have a look.....

Haynes manual it. Should only take a couple of hours to drain it, strip the head, inlet and aux bits off.....

can i be the one to ask (and not being funny... more out of interest)...

how many miles has your clio done, and have you ever had the cambelt done before??

unlucky mate, mine was on 66k and 9 years and didnt have a problem, my old mans cam belt went in his laguna on 103k lol, no damage at all all he needed was a new belt

Even if you time it right, a bent valve going un and down the guide will do the bronze a world of good! (Sarcasm)

Damn right^, theres no way in hell he's gotten away without bending a few valves so I certainly wouldn't feck things up more by trying to start it.

most/all the exhast valves will be bent, never seen one yet damage a valve guide and never seen a damaged piston from a snapped belt. or should i say never seen it damage it in a way that will cause problems bent rod etc

Unlucky mate, too many people neglect there cam belts as they dont know about them, not saying this is the case with u as you where going to have it done but i mean i know people whth 7-10 year old cars that havnt even thought about a cam belt.

Any of the valves can be bent mate, ex or inlet. If a bit of the valve chips off and drops into the bore it'll f**k the piston and bore. I know as it's happened to me!

Unlucky mate :(

Shotgun the bottom end and crankshaft if you have to get a new engine ;)

Engines are 99% the same in the mk1/mk2 forms aren't they? Just the fbw throttle and associated gubbins

you obviously dont no how valves in new engines are designed they are designed to bend the valve head not the stem damege to the rest of the engine is very unlikly and i dont appreciate your comments i am giving advice from a professional pont of view to help him out. what do you do for a living cos you obviously dont know any thing about engine.

he's right pop a belt on turn it over by hand see if anything touches if not try an start it. you may be lucky!! even if one or two are only very slightly bent it 'll still start and if thats the case sell the fukker qouick lol
 
i remember when the belt snapped in my Valvers - 9/16 valves bent and i was only doing about 30mph.

Took the head off etc and saw that the pistons had slight dents in them. Ignored that though, replaced the head with a refurbed one, all new gaskets and loads of other stuff including all belts etc.

Started her up - had her rolling roaded and the print out was 143bhp.......... and this is on a standard valver. Explain that one! lol. Damn i miss that car. Ruddy leaking sunroof.

mate my cambelt snapped doing 85 on the m25 3 months ago and its not wort getting the engine fixed i managed to get one from a scrap yard for 170quid...... never going to fix a snapped cambelt engine for that much.... then i got a new clutch cambelt and aux belt and spark plugs oil and all that for the new engine did that all myself by following the haynes manual. it aint hard as long as you have another person helping. me and my dad in the end got the old engine out and new one in with all the changes i proviously mentioned in 2 days and we had to rent a crane. all in all it cost me 400quid. thought id let you no as if you can get it fixed cheaper than that go for it but my mechanic said its a better idea just to change the engine

Valves will have been bent, theres no point putting a new belt on it before you've stripped the head off.

dont think there is a haynes manual for the late clios!only mk1:S
Yep there one for the Mk2 phase 1 and Mk2 phase 2. Doesn't over RS models though

RR enough said there about as accurate as numbers out of a nat withoutn comparisons

Totally ages its bent a value at leat one stupid even trying a new belt.

you obviously dont no how valves in new engines are designed they are designed to bend the valve head not the stem damege to the rest of the engine is very unlikly and i dont appreciate your comments i am giving advice from a professional pont of view to help him out. what do you do for a living cos you obviously dont know any thing about engine.


So, I bring my car into your garage with a snapped cambelt. You put a new belt on and it f***s the guides because you're too incompetant to just do the job instead of skip ratting it. You now have to put new guides in and f**k about with the head checking for cracks.

Obviously, I know nothing having rebuilt engines myself. It's a contact engine, piston hits valve, valve bends. End of.....

99% of the time, 100% on 16v engines.

But the old OHC engines from vauxhall, the 1.1 punto, the kent x-flow engine can usually be timed up and go again without taking the head off.



Any way, take the cams out, and run a compression test. see what the figures are, if they are all 120psi+ then it looks like your good to go and very very very lucky.

The tensioner pulley came off c16se, result was 3 bent valves. it's uber unlikely to be ok but it does happen on 8vers. I'd put money on there being bent valves, I would'nt waste my time pissing about with a new belt, just whip the head off and replace whats broke....

Nope. Asked my garage today and they said if cambelt was broken they would take it apart and inspect for damage first

Damn right they should to. Its just lazy, wasting a belt and risking more damage trying it with a new belt. Bad practice imo.

Very few engines are non-interference these days, and the renault 16v lumps certainly aren't theres no way in hell theres not bent valves.
