Hello everybody, after 3 years of career, my beloved Punto convertible (176C), had a disastrous failure just a week ago.

Luckily I was nearly home: the engine stopped at a corner, last one before parking, I restarted the engine, parked the car, and went home.

After some hours, I had to go buy a thing, so I went out, started the car, but after a second it stopped running.

I thought was low fuel, so I reached first petrol station with my tank, filled with 5 lt. of unleaded and came back.

I realized after filling, that I had half tank of fuel, so fuel was fine. Tried to start again, and the engine runned. Reassured by that, I switched off and went home.

I tried to start it again a couple of hours later, everything seemed fine, but as soon as I released the gas pedal, the engine died.

In the following days, obviously, the battery died. I asked to borrow a jump starter from a local garage to try start my car again: nothing to do.

They picked up the dead body with their truck and started working on it.

The following morning, they called me and told me that the failure was likely to be cam belt that jumped one or more teeth, maybe by itself, or maybe because of the seized water pump. I was aware it was leaking, since I spent 3 years on putting in water every 2-3 days. They told me that compression in 3 out of 4 pots was dead, so valves were gone, hit by the pistons.

They quoted me something like 700 GBP for having the car running again, but refused to do the job because the car is too old and not money-worthy.

I called another mech that is from my country and usually assists me when I have very little money to spend in the car. He told me was going to be expensive as well, but I know him very well, and usually have better price.

How much could be wise to spend to have the engine refitted? The biggest trouble is that i am pretty sure that also the heater matrix is leaking, because of the stench that feels the car every time i turn the heater on, so should be replaced as well.

Even if we found an agreement, and I pay him back 200 GBP per month, I am pretty sure I will end needing 5 or 6 months to have the job paid, but I can't stand having a new engine and risking the head gasket to blow because of a ****ty heating radiator. I don't want to scrap the car because it has new roof, new clutch, suspension arms, brakes and full exhaust pipe, and also because there are less than 600 still running, and becoming a classic.

I could find a suitable engine for 80 GBP more or less, + 65 of shipping, but the seller told me it requires the head to be grinded and new gasket. But if it's a good engine, replacing head gasket, water pump and timing belt could give it a second life.

Does anybody know a car mechanic around Milton Keynes, that does good jobs at good prices? I am desperate to have my car running in max. 2 weeks, since I have to do a small trip next month, and, most important thing, I am freezing my face going to work with the bike (for example: tomorrow I have a 6.00 AM start, forecast is rain, and I will have to remember a spare pair of socks to avoid freezing when working)

With the tools I have I'll be great in putting a bicycle together (as I actually did), but nothing bigger than that. I know it was a f***headish job going on putting water, but I planned to do jobs when I have money. That's it.
 
Is your car a 1.6 or a 1.2. As far as I am aware, the 1.2 is a non interference engine (not sure about the 1.6), so even if the timing belt has slipped, it should not cause any damage to your valves. Could it be something as simple as the head gasket? This is a common issue on the 1.2 which can be fixed at home and could account for the loss of water and lack of compression. Have a look under the oil filler cap for signs of mayonnaise.

Even if you pay your friend to do it it is still easier and cheaoer to put a replacement engine from a scrapped car into it, than repair the old one (if it has damaged valves / pistons) head gasket is fairly easy.
 
It's an unfortunate situation but it sounds like the car is worth repairing by someone (maybe not you), but they would need to be good themselves or have a economical mechanic or engine specialist to do it for them.

I wouldn't buy another engine if it will need work anyway.. unless you are sure that yours has been excessively damaged by the neglect and final failure.

If your engine only has some bent valves then it should be straightforward to have them replaced (head skim and valve overhaul) and then just refit with new gasket, cambelt and waterpump.

The 1.6 is a tough, straightforward engine. I had my Tipo 1.4 head done (skim and reseat valves) for £60 by a local specialist. Note that the engine will need all the valve clearances / shims resetting so that it runs right, this is straightforward but might be 1 - 1/2 hrs labour and would need a Fiat / Alfa mechanic with a box of assorted Fiat shims to swap in and out to get the right clearances.

Good luck.
 
autodata shows 1.6 as interference engine

as is the 16V 1242cc:eek:

bottom line;

if you've little money - buy a decent manual , and do the job yourself,
parts are readily available,

you'll want a sound used matrix,
and valvegear.. opinions vary on light valve clashes..,

often you'll find that big-ends fail after a few thousand miles( due to the loadings they've had at the moment of dead-stops)

However if you LOVE the car it's ALL worth doing.. just not financially viable to spend @£1000 on a "mechanic" doing the work
