OK................the saga continues further...

Bought a 2 stage rad flush which I have now used.

This is whats happening when stationary..

Engine comes upto temp pretty quickly, heater on and blowing cold
just above 90 the fan cuts in
then (I presume) the stat opens, fan turns off, temp gauge drops to just below 90 and lovely hot air blowing into the car
after a few minutes hot air stops and blows cold, temp rises above 90, fan cuts in, stat opens and hot air in the car again, gauge drops down..

Now you would have thought this would happen all day but it doesnt

after a couple of cycles the temp gauge starts to climb, fan comes on but doesn't stop, no hot air blowing and bottom hose on rad is cold..eventually I have to shut the engine off as temp very slowly continues to rise..

It was doing this with the old thermostat which is why i thought it needed a new one...could the new stat be faulty?? Bit worried as this engine has been through lots of heat cycles...

GE i poured water (at gravity speed) into the top hose and it flowed very well straight out of the bottom hose so I assume there are no blockages there..

I'm all a bit lost now.......

Have done the coolant flush thingy so if there was any crap in the system it should be gone now...

To me, that sounds exactly like a failed head gasket again... Or rather, that is what happened with mine both times it failed. And it wasn't loosing loads of water , just gaining quite a lot of pressure until it escaped from the header tank cap.

It is very unlikely that the new stat would be faulty, although I've seen different ones doing slightly different things temperature wise. Is it a Facet, or something else?

The water pump could still be a bit of a suspect if the rotor has been damaged in any way and come off the spindle. There was a flow of water when you checked it, but without actually physically taking the thing out and inspecting it you can't be certain it's not causing problems.

Compression test the thing first so you can rule out any more head and/or gasket damage!

Here's one I did earlier:

Keep left unless overtaking - Use mirrors and signals when changing lanes - Keep within the white lines - Don't tailgate

Its not exactly f**king rocket science is it?

Thanks......3 gaskets in a month!! surely that can't be right...which the hell could be causing it??

I'll get my mechanic to do a pressure test and then go from there but if it is a gasket failure then unfortunately I can't justify throwing more money at it.

Thanks guys...

Firstly thanks for all your help and suggestions...

I have decided to call it a day with my 146...to be honest I've just lost heart as well as most of my savings and the past few weeks have done me in. I can no longer justify throwing hard earned cash as this car.

It's going to get weighed in in a couple of weeks so if anyone out there wants any bits for example SuperSprint rear box, 17" alloys (see my garage) Sparco adjustable strutbrace, K&N Filter and metal piping etc etc etc let me know. I don't have any space to store stuff and I will need to drive it to the scrap yard (or at the very least tow it). Sensible offers please unless someone wants to chuck 250 my way and you can have the car..

It's certainly been eventful this Alfa ownership!!

Sorry to hear that. At the end of the day I guess you got to do what feels right and there always has to be a limit to how much money you throw at a problem.

If the rest of the car is sound then it looks like a complete replacement engine is probably the best option if someone decides to save this car.

Anybody still here?
So i swapped our 145 CF2 1.6's head to a rebuilt one, and only had 2.0 cams at hand. I installed it, (with the 1.6 tools.. whistle.gif ) car fired up right away, got out at the road, but as soon it got into temps (solid 90c) it stalled. It fired up again, but under 2500rpm, it stalls again. Above 2500 its all fine, but as i let off the gas, it stops.
Will the 2.0 camlocks solve this?

the camlocks only serve to keep the cams fixed in one place whilst you change the cambelt, i'm not sure that is your problems tbh, do you have an injector light on?

Okay, so cams are in time with the 2.0 tool. Cleaned all the earth cable connections, all the connectors, did a reset with OBD and made the car learn the idle for 20 mins.
Now it starts and idles like a rock smile.gif And goes like a rocket...

BUT! I still get blue smoke, when accelerating harder. Nothing on cold/startup/idle.
The whole procedure started as a head job. The backstory is kinda messy... We are the 3rd owners since 2013. A not so alfa specialized mech had the head removed, and he did put it back, and told me it was a bit pitted (i could get a better one in one day if he was told me in time..) I'll please you with pics blink.gif
So i got a renewed head. Skimmed, valve seals replaced, bought a new gasket set. Put it back all together. All the 4 pots have over 12 bars of pressure (about 175psi) and now it works as normal, but still blue smoke.
I checked the PCV valve, it seems normal. I was trying to get a new one lately for our other car, but it seems like impossible.

Any thoughts on this?
