got sapphire 2wd smokes under load, changed stem seals and had turbo reconed, compressions good 7-8 maybe overfuelling temp sensor? causing bore wash help please before engine comes out?fully quallified mechanic so no daft conclusins please! many thanks

 

Have you checked the breathers are not blocked? Do you have uprated breather system?

 

yeah got breather ive tried 10 60 oil which stopped smoked but still used it around a litre to a hundred miles

 

it could be worns oil rings which wont show on a comp test

i guess its blue smoke? if not what colour is it?

what's the idle CO%? do you have an AFR gauge?

 

set co to 3 at work puttin mates wideband on on wed to check down road, its bluey black my mate sez it smells fuely but it uses oil so maybe bore washing oil off being too rich?

 

+1

 

might well be; but obviously, whatever chip you have will determine what the co% is at idle (assuming it is chipped)

if you can open the lid on the ecu and have a look, you'll see a make and serial number hopefully. Phone the chip manufacturer and quote the seial number and they'll tell you what the CO% should be at idle

remember when twiddling with the screw on the ECU, it changes it for the whole Map

its a norris motorsport chip will phone him 2moro

 

3.5% thats roughly wot its set at?

 

never understand why people run a tuned car without an AFR gauge, it's just asking for trouble, get 1 fitted so you can keep an eye on your fueling, it's just as important as your boost gauge if not more!
