Alfa 156 sportwagon, 1.8. 2000 model

Not the easiest thing to explain but i will do my best.

My car gives out WHITE/GREY smoke. Not blue or black. Just need to clear this up.

It uses about a litre of oil every 250 - 300 miles.

Here is the hard part.

From cold the car will do about 60 miles, town or motorway without any smoke what so ever.

Here is the harder part, i can feel on the accelorator getting harder and harder, and as long as i dont push the accelortor past the hard part, there is no smoke. However the hardness comes and goes, normally if im on a hill it gets hard and i can only do about 60mph before i see smoke. With this hardness on the accelorator i can still get up 80-85mph without any smoke, or any problems, as long as i drive how the car wants me to drive, ie not pushing her to hard when the accelorator feels hard.

If i push hard down when the accelorator is at the hard part, i will create a HUGE massive white thick cloud of smoke, this hangs around for 10 - 15 seconds, and is very dangerous as you can not see through the smoke. It stanks of oil. I will then get constant white smoke for a few seconds, this can sometime last up to a minute.

The car has just been serviced, and an induction kit added (this was added as it was easier then replacing the air filter housing) I am using 10-40 oil, but i have just bought 8 liters of 10-60, the oil cost £78 so dont just want to stick it in the car to burn off.

I have seen smaky post about the inlet stub manifold, but i cant see a way to take this off, any help on this would be great.

The water in the coolent system is clean, no signs of oil, the car never gets hot unless i am stood still for about 10 minutes. And by not hot, the in car reading needle looks like it never moves (it works as it rises when i am stood still for a few minutes)

There always seems to be a lot of water in the exhaust.

1 last thing, i was rev'ing the car outside just to see if there was any smoke. there isnt unless i get the revs over 5,000 RPM, and then i get white/grey smoke every now and again (nothing major), I rev'ed her up to 6,500 RPM for a second and got a nice blue smoke, this is the 1st and only time i have seen blue smoke from her, as i normally drive her at around 4,200 RPM.

Any ideas on wat to fix with these problems would be great.

thanks.

Few other points i should add.

The car has done 73,000 miles... it did 62,000 of these in the 1st 2 years of its life, then the other 11,000 other 7 years. When i bought the car it hadnt been serviced in 2 years, but apperntly had the head gasket, timing belt, vaule stem changed, and some other things done to it, i can not comfirm this as there is not paper work for it, but the timing belt dose look nice and new.

Just found the Exhaust Emissions test results from january, and it passed all these, this was done at the time of the MOT. In jan it had 70,000 miles on the clock, so has only done 3,000 miles this year.

valve seals? head gasket possibly piston rings. Does it use any water? When engine running take the cap off the header tank and see if there is bubbles in the water, if there is it could indiacate a head problem. Also take the dipstick out when engine is running see if any smoke is coming out. If so this could again indicate piston rings .......... Anyone feel free to correct me.

Just a thought could this happen if timing is slightly out?


Good luck fella anyway.

Well, the accelerator issue doesn't sound right .. it should be smooth right through the range of the pedal. And as you know, you are using far to much oil ...

Oil is getting into the system somewhere (obvious!) ... but locating it will not be easy without a possible strip down. If the valve stems seals are newish, then I'd probably go for piston rings and/or bores. But then again it may be coming from the crankcase and being pushed into the intake system ...

There are two crankcase breather pipes: one comes joins the intake before the throttle body (that's the small rubber hose joining onto the rubber intake section coming out the top right hand corner under the engine cover) and the second goes backwards to the inlet manifold behind the throttle. This 2nd breather pipe is harder to see but it should also have a valve (simple plastic plunger/spring) which opens when the pressure increases at higher revs.

There are some pics on my website of the engine bay and also some info on that oil valve as I had problems with mine after an engine rebuild ... although it only caused a high idle speed. But they may help you pinpoint something .... check under Hints & Tips and "Idle Saga!"

The breathers from the engine are part of the emissions system to burn off excessive oil. It might be possible to re-route the breathers one at a time to a catch tank (like race cars use) .. and plug the pipe to the intake system to avoid air getting in. That will show you if excessive oil is being blow out of the engine which would point to rings and/or valve stems. A compression test may also show if the rings are suspect as it would be lower than usual as you won't be getting a proper seals between the rings and the bores.

Hopefully this might get a conversation going for you ... ;)

you gotta realise why is the oil being pressurised through the intake system i would say get it pressure tested you will find out if you have a piston problem or not probably find it is the cheapest option at this stage and will be the most useful .i would say if it is pressurizin the sump you have a rings issue / piston liner a pressure test will confirm this .

never got a engine rebuild in the end.

I am currently using 10/60 oil, and the cloud of smoke has gone from a cloud ever now and again to a puff every now and again, burning a lot less oil, but the car seems not to run idle as well as it use to.

I am going to try and get this inlet manifold gasket sorted, but not sure where to go from the point i got to.

I removed the big black box thing from the back of the engine, the one that is held on with the 4 pipes/tubes, and found no gasket, so i am guessing that i have to remove the 8 bolts from engine now, and put the sealent in there?

Would i be better off getting a whole new gasket rather then using a sealent?

another update.

The car will only smoke once i have switched the engine off after drving for a long time, and switched it back on, the smoke is less but seems to burn off for much longer, not blinding clouds, also forgot to point out that the smoke comes out of the oil hole (where you pour oil in) still this black isn't blue or black, its still white.

DRove 410 miles with the new oil and have lost about half of wat i normally lose, so the car likes the new oil, but still having problems.

Will be atemping to remove this gasket tomorrow.

Sounds like a head gasket problem to me , water is getting into your oil and causing the white smoke/ steam on combustion , a sign of it is milky beige coloured froth forming on your oil filler cap, i had it on a VW golf once and a new head gasket and skimmed head cured it .>
