hi all we bought a volvo 850 2.5 none turbo 10v and its drinking oil and when we stop and then pull away we have blue smoke coming out the back, then it clears, had the engine block tested and there's no problems, the water is holding in the system, there's no oil leaks and we have used 1litre of oil in 2days. hope some1 can help us out

any leaks you can see? that is a lot of oil in 2days.

 

no leaks at all

 

Make sure the oil is not over-serviced.

Make sure the PCV is in good condition.

Make sure to use the OEM filter (MANN).

What oil have you been using? As a temporary remedy, try using heavier weight oil, such as 10W-40. If blue smoke is spitting out of the tail pipe, oil is still entering the combustion chamber somehow. Strange.

If the oil level is correct and the PCV is not too hideously faulty, I would have the engine for compression-tested again at another reputable shop, even if the coolant reservoir level has not dropped and there is no sign of fuel in there.

hi service light is on and it needs a service, oil used was castrol high millage £5.98 ltr.

 

Being this is a non-turbo, there has to be oil getting in somewhere. Did you have the engine compression checked? If so, what was the numbers?

 

hi there, car-going into garage thurs, and no not had compression test done as yet. what readings/figures are we looking for on the compression test to tell us it ok, and i take it they should be reading around the same figures.

 

They should all be about the same. I forgot the range, but if two or three are different by a good amount, then It is probably going to need an opening. piston rings, valve seats leaking....etc. wait for tech to say something...

 

If it smokes that bad and it's not leaking, I would guess it needs a bottom end rebuild. Especially since it's a non-turbo.

 

thanks for the advice guys, will c what the garage has to say in morn.thanks again.lou and andy.
