Hi guy's,i bought a shift light the other day,fitted it and all works fine ,now the thing is i had to test it out and after a couple of times driving the car and changing at 7k revs i did the usual wind down(drive for a couple of mile at normal road speeds) and then reversed onto my diveway and let the car tick over for about 5-10mins,after about 5-6 mins it started smoking from the exhaust,a bluey grey smoke :twisted: for about 30 seconds and then cleared :? Took it for a run last night with no problems :? Started the car up at my mates today after it being stood for about 2hours and after about 5-6 mins samething......started smoking again :twisted: and lasted for a couple of mins this time,so on the way home i cut the turbo in (nothing mad)and no smoke and no problems,reverse back onto the drive and leave it ticking over again samething again :twisted: smoking again for about 20 seconds,then cleared :? :? Took the spark plugs out and they were fine,no signs of burning oil :? :? Also no oil in the intake or dumpvalve :? :? Any ideas :?: Could it be the turbo oil seals but only on the exhaust side :?: Also if it were rings or ringlands wouldnt it smoke all the time :?:
