I can only think of two reasons.

1. He didnt actually change the gaskets!!!! Hard to believe.

2. Did he skim the heads? They might be in a bit of a state possibly even need replacement but he should have skimmed them.

Good luck

As above, sounds like it hasn't been skimmed. Especially so as he's paid you back so easily and not tried to blame a third party (who usually do the skimming on behalf of the garage).

I agree with the above - if he has changed the gasket chances are he didn't skim the head.

Did he show you the old gasket? I always pay a visit when serious work is being done to inspect the progress like when my 164 was done. Sounds like he detected a loose head so simply retorqued the head and off you went thinking you had a new gasket. He took a gamble at your expense but I imagine he will fix it properly this time... Needless to say, don't go there again unless he has a reasonable explanation of what has gone wrong (faulty gasket).

head skimming not always a cheap addition to "new gasket job".
Most often the head needs to be stripped (valves and springs), so machine shop can bolt it to their table. While you are doing this should you also inspect and renew any valves/guides/springs/valve stem oil seals etc etc etc ?

Definately. That's the exact treatment my 164 received and we're talking 2 heads and 24 valves so it wasn't cheap and took 4 weeks.

We're talking about a V6 then? Definately could have done one and not the other but then you may have a non related issue as in, your fan is not kicking in when it should causing the engine to overheat, if it overheats, the head will warp and hey presto, no gasket seal. Also, he may not have torqued to the correct tightness which will cause the heads to fail. The 24v uses stretch bolts so you need to torque to 'X' lbs then loosten and then retorque to 'X' lbs again and all in sequence. Don't get this right, and it will fail. You do not ned to retorque again after running in as you have said stretch bolts but, if the procedure was not done correctly, it will fail pretty fast. This is why I do not allow anyone near my car who is not an Alfa trained specialist and has a track record of working on V6's. They are tricky to get right.

There's something weird going on here...

Why should a failed head gasket cause the temperature to shoot up? I could see it happening the other way round (overheating causing a head gasket to go). I could also see the car gradually running hotter and hotter as it puked its coolant out (because of a failed head gasket), but I'm not sure why the temperature should suddenly go up.

Had the car lost any water on its run? What was the level like when you got back and had left it to cool? Similarly, had it "gained" any oil on the run? (in other words, had water gone into the oil, increasing the level on the dipstick)?

Sorry for the blatant thread hijack, but I had a look at your Spider thread - (most impressive, I have to say!) and saw that you'd painted your cam cover a couple of years ago. I've been thinking of doing the same and was wondering how it had lasted? I did it on my last 164 V6 and it looked great. I used Plastikote red paint from B&Q, 'cause I happened to have some, and then sanded the high spots off so that the aluminium showed up silver. I then painted over the lot with Halfrauds own clear alloy wheel lacquer. They looked the business for about 2 years and 20,000 miles, then started to corrode, and now they look pretty rough.

because when the coolant runs low when it is going either in the oil or in the combustion chamber and out of the exhaust as steam, it gets low on water, or air gets in and the sensor measures much hotter air.

chicken and egg I suppose, HGF causes overheating, but overheating causes HGF

that was the issue it had when I saw it, coolant in the oil, looked like coffee

Well at least he didn't skim alfa156156166.Now that is a result.

Maybe he changed one gasket but not the other. :confused:
OR he stuck k-seal or other proprietry sealer innit.And the gamble did not pay off.Too quick to return dosh wie no arguement IMHO.

i'm guessing this was one of the numpty "mechanics" you asked about the original problem? If you wanted to get it done you should have got it done by a proper mechanic....
