Blown head gasket

The head gasket on my alfa 156 jts 2004 has just blown...in the middle of a busy car park. Drove it to the mother in laws house about half a mile away. It will be in the garage in an hour but I'm wondering if its worth the money to get fixed (probly £300-400) as it is in good condition and i really like the car but would like to know if this will possibly damage other parts of the car.

Thanks, Eric

Sorry to hear this.

I guess it depends on the condition of the car and how much money spent/how well you've looked after it to date.

You would also depend on the garage in question to know their way about an alfa and give you an honest, even if hard to hear, assessment!

400quid is not a huge amount of money if you caught it early enough and nothing terminally over heated or warped....and particularly if you know have a good car there

Keep us posted
regards
Tony

Mine went on my TS .. I changed it myself (only because I wanted to and it was a '98 model!) .. afterwards it ran better than it had for a long time.

I guess potentially the cat could be damaged but I think that runs so hot any water would turn to vapour/steam .. hence the white exhaust smoke!

Otherwise .. unlikely to. You'll need a oil and filter change too.

I DID replace the head bolts .. mine had visibly stretched but the engine had been apart a couple of times in the 210,000 miles .. cam belt failed and then big-end bearings about a year later! It was a small outlay to know it was going to be a good engine again.

cheers, Gary

Yup!
So consider that mines needs discs and pads all round. When the drivers side was stripped down...needs a caliper too (groans)
Parts alone its 250quid. If only i had the time to do this myself .

My head gasket might blow in 12 months.
Id already be too far into an outlay to NOT get in fixed(if it was fixable).

If your timing belt and pump are due, even if its 12months early, just do it all at once and itll be good as new 👍🤞

It won't be £300-400. Start thinking more like twice that. there is a bit more to the JTS than a TS. Also, if the head is off, you have the chance to do the obligatory decoke to inlet valves and ports. There should be no subsequent damage.

Parts cost will be about the initial hoped for cost.
Cylinder head gasket set £120
Timing belt kit £150
Engineering shop costs £100
Labour- say 10 hours £500
Consumables & fluids £50

When I looked at mine, it became obvious the valves needed to be removed before skimming the head. Prices have gone up for this sort of thing in the past couple of decades and newer cars will easily swallow £1500 in many cases (even for 1.6 TDCI/HDI engines as fitted to Peugeot, Citroen, Ford, Mazda & Volvo).

Thank you all for the replys. The timing belt and water pump is a great shout. Reason the work will be so cheap is that the mechanic is a long time family friend btw.

Soon to be past tense.

Seriously though, remember about the balance shaft belt and possibly idler and tensioner. The decoke will probably release 30bhp and make the engine run sweeter and rev so much more freely. Make sure to use the correct timing tools as this is important to achieving good performance.

Check the auxilliary belt tensioner for spring, alignment and bearing wear. If necessary, get a new auxilliary drive belt. Finally, treating it to a sump-full of decent 10W/60 won't harm it either.

If all that is done right and it is as carboned as expected, you won't believe it's the same engine afterwards.

My car repairs are currently underway with all new parts arrived. I was reading on my e-learn repair manual on the computer that the a/c has to be drained and the compressor removed to do a head gasket and full belt change on my 156 jts.

Can anyone else confirm that is definite as i dont want to pay for a recharge again 😂😂.

Is there a way my mechanic will do it without taking off the compressor?

you could just unbolt the compressor from the engine, leaving the pipes connected, and support it against the slam panel.

Or find a piece of wood supported by radiator bracket/engine mounting.

The cylinder head is being skimmed, yes?

Yes the head is being pressure tested and skimmed...didn't realise the compressor was bolted to it 😂😂
