Lukey. 381 Posted April 28, 2011 Report Share Posted April 28, 2011 check your oil again Link to post Share on other sites
dman78 1 Posted April 28, 2011 Report Share Posted April 28, 2011 had black smoke coming out of mine when i started it up aswell,been told that means its running rich,is your oil air cooled ie mocal oil cooler or still water cooled? Link to post Share on other sites
VR6Pete 1,455 Posted April 28, 2011 Report Share Posted April 28, 2011 Have you had it mapped since fitting? Link to post Share on other sites
Lukey. 381 Posted April 28, 2011 Report Share Posted April 28, 2011 you could just have a boost pipe come undone, that could cause grey and black smoke, also turbo seals could cause the grey smoke if its on the white side Link to post Share on other sites

Lukey. 381 Posted April 28, 2011 Report Share Posted April 28, 2011 if your boost pipe is off it will be overfuelling like crazy cos it will be expecting so much more air in the cylinders that the turbo compressed into them, with the boost pipe off its just atmospheric so the amount of fuel will be totally disproportionate to the amount of air it is expecting to be in there, so overfuels and you get dirty black smoke Link to post Share on other sites

Lukey. 381 Posted April 29, 2011 Report Share Posted April 29, 2011 the oil light will not be related to this, you need to sort this problem out additionally, if the oil light is on i would first re check the level and top back up again, if the level keeps receeding then you need to source the fault Link to post Share on other sites
vr6guy 29 Posted May 4, 2011 Author Report Share Posted May 4, 2011 hi guys i have fitted all boost pipes now and i have a misfire and definate over fuelling problem!!all 6 spark plugs are black! swapped ht leads, no change and changed spark plugs, no change.i was thinking it was down to wiring/plugs as ive used the old wiring loom on the turbo engine (all wiring is the same) but i noticed on the turbo engine it had the brown sensor missing which is located on the front of the engine near the gear box (next to the blue and yellow sensors)so i took the brown sensor of the old engine and put it on the turbo engine... i didnt no if that would make a difference ? or whether thats to do with the aircon?also i found oil leaking from the top plug (one of three) on the oil filter housing, it leaks out quit quickly when engine is running.... maybe that would cause oil light to flash??thanks guys!

vr6guy 29 Posted May 4, 2011 Author Report Share Posted May 4, 2011 also theres a plug that goes onto the air filter housing (i think thats the MAF plug/sensor) which isnt plugged in as the air filter is now on the right side of the engine... i read that might make a difference to the fuel? thanks again vr6 lovers!!

Alex22 0 Posted May 5, 2011 Report Share Posted May 5, 2011 have u had it remapped yet mate as the computer will be trying to do things it thinks will work for the old engine, that that Link to post Share on other sites
Lukey. 381 Posted May 5, 2011 Report Share Posted May 5, 2011 a loose sender on top of the filter housing would probably cause low oil pressure yes which would trip the low pressure sender to turn the light on. Link to post Share on other sites
