156 2.5V6 cam pulley failure


I have an alfa 156 98R with 60K miles on which the cam belt just jumped 2 teeth and has wrecked the engine.
The cam belt an tensioner were replaced 4K miles ago in June/July and since those parts are under warranty.
The dealer who currently has my car having already charged me a thousand pounds for finding the fault now suggests a recon engine at 5421 pounds.
Because the cam pulley was worn and that caused the failure, alfa romeo refuse to cover it.

Anybody have any coments ?

I can't quite figure out how a worn cam pulley would cause it.
Ask to see the offending pulley as proof.

Did the same garage do the timing belt and tensioner? If so how is it that they didn't spot the worn pulley then and warn you?

All sounds a bit odd to me....worn cam pulley???

I would say thats been bad service, all belt stuff should be changed same time, and official interval is here 37000 miles

Re: 156 2.5V6 cam pulley failure

A worn cam pully? that sounds weird. Do you mean that the teeth on the pully were worn and not defined enough any more, or do you mean the bearing at the pully end was worn.

I can`t see how pully teeth could be worn enough for them to diagnose this as the problem after the event and yet not notice it 4K miles previously when they changed the belt.

Also, how can it cost that much to diagnose the fault! A broken cam belt should take them 30 minutes to diagnose at the most!

Unless you are extremely unlucky I doubt that the engine is destroyed. You may need new valves etc but if thats expensive in labour for you, get a second-hand head from a scrap yard. It depends how much you want to spend. Can you post the exact damage they have quoted?

You have given the price of the recon engine but does that involve the cost of removal of the old one and fitting of the new? If not then you might be happier with buying a new V6 car complete which could be less money. If you have the space for the old car you would be able to sell all of the bits off it in no time and get some money back.

All in all it sounds deeply suspicious. I could guess that not locking the cams properly when they changed the belt could cause wear on the teeth and belt failure if one of the pullys was put slighly out. Also, was it the correct belt (they do sometimes fit the wrong belts to cars you know!)

As a final suggestion, have you though of having an independant report done on the car by the AA or other professional body. That will at least stop you getting ripped off by the dealer if it was their fault. I`ve seen posts on the forum where such reports have saved people from big bills.

Re: 156 2.5V6 cam pulley failure

Yeah - that dealer is bent.

How can they charge you that much just to look at what's wrong - even at 60 an hour your grand would buy 2 days of mechanic time?

I'd ask them to list what they racked up the bill on - every job has a "recommended time" that even indpendent specialists use. I presume your dude is a pukka dealer?

As for the fault - if you used genooine parts and a genoouine dealer there must be some redress. You'll have to find out what's what and only an independent engineer's assessment is going to give you that.

4000 miles suggests they didn't do the job properly and something let go as a result, OR there was something so knackered in there that they ought to have spotted it. Get your engineer to investigate, then use his report to sue the *******s!

Don't leave your car there so they can fiddle it in the meantie, either. Or if you do, don't tell them an engineer's on his way. I'm convinced they f*cked it up.

If you get lumbered with fixing it with your own money:

At 5k the recon' engine isn't worth it.

You can try repairing yours - which is what your dealer would probably do to come up with the aptly named "re-conned" unit! (you have been mate!) independently. It may be cheaper as you can just buy the bits you need and that MAY be "not many".

Or buy a second hand engine yourself from a wreck (it was running alright when it crashed! but you can give it a quick overhaul while it's out - belts, pulleys!, clutch and so on).

Or sell the car and buy a new one, using as many bits as possible.

I'd go for option 2 as if you ever get round to fixing your original engine (when you can afford it) you have a saleable asset which some other fella will be grateful for.
