howling mad murdoch 4 Posted October 21, 2008 Report Share Posted October 21, 2008 as the tittle says its defo blue smoke which worries me , it only does it when warm, if i boot the car and load it up i get no smoke, if i drive gentle i get no smoke if i coast up to a junction pull away hard or softly i get one big puff of blue about 25% of the junctions then its gone. is this crank case pressure building up or do you think i have another problem thanks Link to post Share on other sites

crish72 0 Posted October 31, 2008 Report Share Posted October 31, 2008 Piston Rings...mine does it after driving downhill then accelarating... Link to post Share on other sites
howling mad murdoch 4 Posted November 4, 2008 Author Report Share Posted November 4, 2008 piston rings would smoke on acceleration tho, and its only when hot so if any think it would be bore ovalisation not rings.found a quote on here somewhere will dig it out, if you coast for about 30 seconds then accelerate blue smoke will mean valve stem oil seals.

howling mad murdoch 4 Posted November 6, 2008 Author Report Share Posted November 6, 2008 ok see your point but it wont smoke after that first blip and i get none at any other points of acceleration even if i really open it up, could it not be worn guides letting the oil in on overrun the that first blip blows it out the exhaust cos it wont do it again after that??
