2004 S 40 Burning Oil - (black smoke at high revs only)

55k on clock no leaks, rattles or noises - cat was choked up now sorted

my thoughts are its probably valve seals,could it me anything more simpler?

(Just been serviced at volvo main dealer who diagnosed cat fault)

1 opinions / thoughts please

2 repair cost in uk?

cheers

 

Black smoke means running rich not burning oil.
Blue smoke is oil.

 

heheh never even thought that 1 through did I

Son has just had a new exhaust made with a sports cat, so maybe its just a diagnostic and tuning to suit new set up

(whoooopeeeeeeeee maybe he wont be coming on tap for some cash again)

Thanks a lot will post results after tuning

 

Opps

garage think either valve seals or rings

£400 labour + parts for either 1

no garauntees its not the other choice if I choose to have just 1 done

so it spend £1200 or get shut i think

 

Have them check the vent system first.

 

(Have them check the vent system first. )

is this something i could check?

if it was mixture could it be adjusted manually or has it to be garage job

cheers

 

just been out in car with r kid to see what problem is

it smokes when you change gear or accelerate hard

exhaust is very black at end and smoke seems to be blue ??

think it may be as garage said myself

going to try other garage first

maybe easier just to swap engine ?

 

I highly doubt it is a major engine problem.
BLACK smoke means running rich maybe a vacuum leak or something like that.

 

confirmed engine is burning oil

vent system clear

garage quote more than cars worth

priced replacement engine - still mega after spending a lot already

time to part ways - Car now sold at fraction of purchase cost and after a lot of cash spent.

Luck of the draw unfortunatley this one was a bad one and had obviously been abused prior.

 

That is very odd. It really must have been beaten and overheated really bad before.
