Technical 1.6 Rough Idle after cambelt change

[Gregovic]

:bang::bang::bang::bang::bang::bang:

Had my cambelt changed last week, as I had no idea when the belt was changed last. Decided better safe than sorry. Belt looked almost like new, both the tensioner and idler pulley's felt a little rough already when turned. The aux belts were OLD and deffo needed a change.

Problem now is the engine won't idle or run below about 2000 RPM. When cold the engine starts and seems to hold a rather rough idle at about 1200 RPM. As the engine heats up the revs drop to about 1000 and the running gets rougher and rougher. Then it just cuts out. Above 2000 RPM the car runs reasonably well although it seems a little gutless and not as smooth as it used to be.:yuck:
When I picked it up he mentioned it ran a little rough, but I thought he actually meant a LITTLE rough (And it used to be at idle because one of the injectors is on its way out. It purred like a kitten when it warmed up though). He assured me the timing of the cam pulleys was spot on for both his own marks and the originals.

The car is currently back at the garage, he's having a look this afternoon. Anybody got any good idea's what the problem might be? I'm getting really sick of this car atm. I love it when it works, but there's always something broken the last few weeks.

Timing belt will be slightly out, ask what locking tools he used to set it up.

:bang::bang::bang:He didn't use any locking tools :bang::bang::bang:
Cause that's how he always did it. (And the guy claims to be an ex-fiat mechanic as well)

He's borrowing a set of locking tools to set everything up tomorrow. Got an old Renault Twingo to get home. Forget what I said about hating my car. I miss it already after driving that... "Thing"

Common mistake, you just can't take liberties with 16valve engines... On the good side maybe you didnt get any valves bent...

 

[Gregovic]

I haven't heard any weird noises so far, so yeah. I think I'm good in that regard.
If it does have valves bent the car will be a write-off. I just don't have the time to do a complete head repair myself, and I doubt a garage is going to bother if the car is not worth that much anyway.

 

[Ffoxy]

The bloke who mis-timed it should do the work for free if his incompetence has actually damaged your engine....

 

[Gregovic]

I doubt he'd put in that much time. If that were to happen he'd probably just pay me the cars value and be done with it. Total cost for Cambelt+aux-belts+waterpump and Oilchange was already about half of what the car is worth in total so he'd have to do the work damn fast if it's to be more profitable to repair the engine than to "buy me off".

 

[Ffoxy]

I'd take that as long as it wasnt bottom book value, as it's him that dropped it to that level.

I'd accept average market value.

Luckily I don't have to take it, he got it running smooth again. He claims he never changed anything and just checked it with an angle indicator and locking tools and that it wasn't more than maybe half a degree or so out. I still suspect he just cocked it up somewhere and doesn't want to admit it. Not really my problem though as long as it keeps running. (It actually seems a little smoother than it used to be)
