Saturday morning everything was fine with my 155 1.6 twin spark. (1996) Then the temp went up.
On opening the bonnet oil and water were squirting out of the plastic expansion tank for the water.

Please write and tell me it is not serious!

OK what are the chances of it only being the head?????

Sounds like you have a blown head gasket, especially if the water/oil was being forced out of the expansion tank. Not that serious, but will cost a few £

I was told by my local mechanic that if I have oil in the water it is 99% the block. If it is water in the Oil it is the head.

No milky deposit. Clean and all the oil mixed with the water and shot out of the expansion tank.

Oil in the water sounds fairly bad, and to me pretty unusual - normally the water mixes with the oil as the water is at a higher pressure...

I would suspect the head gasket or a warped cylinder head/ block - your engine need stripping and checking out properly.

It may not be as terminal as it sounds...

Cheers

May not be the cylinder gasket then.
Have you tried a compression test on the cylinders.
All the cylinders should be roughly the same compression, a deviation of more than 1 bar (or 15 PSI) will indicate a problem.
When you do the test make sure you take out all the spark plugs (this will save overloading the starter motor) and the throttle is fully open. Note down the readings and let us know.

OK. The sh** hit the fan.

Engine block is cracked. The problem is where can I find a 1.6 engine block? If I put a different engine in the car (1.7 2.00) What else will need to be changed?
Any ideas??
Thanks

The ECU would have to be changed.
Not sure what else though. Sorry to here the bad news.

Front brakes are larger on 2 litre cars and perhaps the gearbox ratios may be different???

You are best off trying to get a new block. If all else fails then try the welding option.
I had a liner put an a-series engine and it only lasted 20 mins before it lifted the cylinder head of the block. :mad: After all that hassle I ended up getting a new block anyway. (This was a race engine as opposed to a normal road engine)

You could try the scrappers for a whole engine. Keep your old one for spares.

I was only thinking that you would have less hassle to fit a whole unit than lots of fiddling around with bolting bits together.

SHE LIVES!!

Complete engine rebuild,warped block, head. Not a cracked block as I was lead to beleve. New clutch, belts, variator. And a huge hole in 800 quid. And my wife didn't even complain.

I was really pi**ed to be told that the belt was worn despite having a stamp from a Alfa dealer in the service book stated it had been changed 3000KM ago.

A huge thank you to Poweralfa for finding me a block (although I did't need it) And a big finger to all the other Alfa dealers and so called specialists that couldn't bother to reply to my e-mails.

I am almost happy, My baby is back on the road. Now I must just get the mechanic to sort out all the electrical problems caused by the rebuild (lose wires). :mad:

Thanks for your help

Ok got the car back, holds back, so has gone back to be tuned. Now I have a problem. When I dip the clutch revs increase fron 10,000 refs up to 20,000 then slowly drop again. Any ideas?

My brakes froze on (New cables as old ones snapped).is it really true that we should not use handbrakes overnight in cold weather?

Wow, that has got to be the highest reving twin spark in the world!! :D

You may find that the original cable routing has been mucked about with, especially with the engine being taken out. Clutch cables tend to need a lot of force to get moving and when the clutch is depressed it initially tries to straighten the cable.

So if the throttle and/or clutch cable has been moved it may be interferring with one of the others.

I could be wrong but it's a thought.

Hope you get it sorted.
