147 JTD

Timing belt snapped - 147

Hi, i've had a look through other threads but can't seem to find anything like this previously discussed. My 147 JTD (05) 72,000miles has been having low coolant levels for the last fortnight, regularly topping up. Last week the engine management light came on and i lost all power. After gving it time to re-set itself (as has worked before when i was having problems with crank sensor) it restarted, but died a couple of times on the way back home (only a few miles). It was booked in the garage the followng day, so asked them to take a look. (last visit to garage was at 70,000 miles service)

I was told that the car needed a new water pump and whilst at it to do the timing belt. They couldn't get their diagnostics to work on it so advised to book in at Alfa specaist garage (non-dealer) to look at the engine management problem (by this time it had re-set and light out). Car booked in for a few days to do the work, they said ok to drive home but water pump squaking a bit. Drove home (less than a mile), by the time i pulled up at home there was a bad smell and some smoke coming from the engine. Rang the garage and they said to bring it back. Said i'd leave it a few minutes to cool and head back. Started her up and drove about 100 yards and the car just died. Wasn't able to get the engine cranking or anything. Arranged for a tow to the garage the next day, where she has remained. Been told today that the timing belt has snapped, they're putting a kit on it to see what damage has been done.

Could the timing belt snapping have been predicted by the garage? There's no way i would have drven it anywhere if i'd have known it could be this serious

They're getting back to me with more details tomorrow and i just wanted to check out my optons. If we're looking at a rebuild, from looking at previous threads it seems best to stick to your engine as you know what's what. Cost wise though i'm just wondering if there is a lot of work needed doing whether it will still be worth doing or selling car as it is? Car in good nick apart from this.

Any thoughts/suggestons gratefully received.

Cheers

Dunno about this one, doesn't really sound like a cam belt problem to me. The smoke and bad smell points towards a seized alternator or something else driven by the aux belt. The water pump is driven by the toothed cam belt so if that had seized then its game over right away.
The fact that the engine won't even turn over also points towards an aux belt problem.

Do you mean that the water pump seizing could have caused the timing belt to snap?

I wonder if the aux belt snapped and took out the cam belt. I've heard of this happening before.
The garage don't sound like they are familiar with Alfas as a failed cam belt on your engine will break the rockers, no need to put a new belt on to see what happens! Don't think you even need to take the head off.

A seized water pump is the most likely reason for a cam belt to fail on the JTD engines.

True Dave, we don't know which engine we are talking about yet. The 8 and 10 valve engines don't have the water pump issue like the 16 and 20 valve ones do.

Yep, missed that one.
Obviously any cam belt driven water pump failing will destroy the engine. My point was that its not a known fault on the OP's engine.
Non of this explains the cutting out problem however!

He is a she, but thanks guys All advice much appreciated. I'm assuming rebuild costs are going to be mainly labour. I guess i'll now more tomorrow but just trying to prepare myself for the worse case scenario. So, for a rebuild, i'd be looking at new pump and timing belt (already quoted all in for just over £400), then valves, rockers if they're knackered (any idea how much these are for parts?)....etc

Could the cutting out of engine have been due to a sensor relating to timing belt or water pump?

cam belt failing cos of pump will make engine cut out permanently
water pumps fail cam belts snap air flow meters fail lambdas fail cats fail,coil packs as well not everyone comes on here ,or other internet forums to find out,why or to say
so far we know cam belt has snapped whether or not it was water pump that caused it ,could be just coincident

Sounds to me like cars is suffering from more than one problem, water pump causing belt failure on diesel Alfa is classic we see them every day. If it is an 8 valve engine (5 speed gearbox) than it is a head off extensive expensive repair, if it is a 16v (6 speed gearbox) then it is an easy repair if the repairer knows what they are doing. We do end up putting a lot of botched repairs right.

That one that had 8 good rockers, 9 broken ones and loads of black silicone everywhere was a classic.
