Hello, i live in Turkey and i have Alfa Romeo 145 1.6 Boxer (1995). I have a big problem about white smoke and high fuel cost. I changed the lambda, air temperature and water temperature sensors. By the way, the mechanics said there is an electrical installations problem in my car so they can't read the problems via computer. After changing the sensors the fuel cost increased (became double) and in the cold weather there is so much white smoke from my exhaust. There'is no water or oil decrement and mechanics say that boxer motors make this smoke and this says that your engine is healty. But before changing the sensors i didn't have fuel cost problem. The mechanics in my city don't want to take care of the car and this is the biggest problem. I want to change the cables of these 3 sensors' (lambda, air temperature and water temperature sensor) cables. Is there any manual or anything that shows the cables' ways and connections that i can print out and show the electrical mechanic?

hi ctasal,

welcome along

you will find the wiring information in the Technical section, under Manuals.

Everything that you need is there.

However, I have to say, from the symptoms you describe that you should first perform a compression test on the cylinders- as it sounds like you might have lost a piston ring.

The issue might be more mechanical than electrical.

Hi Dante Giacose,

Thank you for your help. Is there any possibility that catalytic converter couses this problem? There is a catalytic converter cleaner which is used from air intake (after air temp. sensor) and they say it cleans manifold, converter and the lambda. Shall i use it? There is a bad smell from exhaust (really too bad) so i thought about the converter.

hi ctasal.

sorry- no; I don't think there's a chance it could be a catalytic converter issue.

The symptoms you describe of smoking and high fuel use immediately point to a loss of compression in the cylinders. (in my mind)

I am afraid it is probably a serious mechanical issue.


can I ask; what is the mileage on your car, as shown on the odometer..?

Oh, no. I hope it isn't. The mileage is 270.000km.

that's 167,000 miles in the U.K.

that's alot- especially for a 1.6, and would entirely support the kind of wear that could cause a seal to fail

There is the possibility that you have 'only' lost a valve, or a valve seal.

A compression test is the first thing to try I think.

Or, you could try to fit a more modern engine, within the existing car...

It depends how much you have to spend, and how much you love the car. It's a grave shame you cannot find a marque specialist to help you. It's probably not an enormous job.

Thank you. I'll try compression test first. Nobody wants to work with boxer engines here. About buying a modern engine here is not as cheap as England. For example the engine that you linked is 400 Pounds and it equals 2.100 Turkish Liras and i earn 3.000 Turkish Liras per month. Because of the high taxes this price becomes about 5.000 Turkish Liras sad.gif

good heavens ctasal,

that's a lot, and obviously too much

I'm afraid I don't know too much about the boxer engine, and what can be achieved with it still in the car.

the compression test will be the starting point.


can you post a picture of your car & engine..?

lucky I'm at work!

Thank you again. Yes it's a good car and the engine is clenaer than the photo now (photo was taken 3 months ago).
