Taggy Posted June 15, 2011 Share Posted June 15, 2011 My car decided to dump shit loads of oil in my exhuast a couple of weeks ago, so much so my exhuast was full of it and my rear boot was covered in it.I had originally put it down to my turbo seals blowing their guts out, but i found it very unususual as i lost over a litre of oil in the space of 2 mins of driving. (I suspected it was in the exhuast as there was so much coming out the back).I have since bought a new turbo and fitted it today, however it seems i may have a bigger problem as it hasnt fixed it, it doesnt seem to be losing any oil but its puffing out blue smoke like a train on boost.The car doesnt smoke on idle or when you rev standing, but when you drive on boost it smokes really bad, the car also starts to misfire badly on 3 cylinders. There is no oil at all inside the blower pipework of the turbo, so the oil in the exhuast smoke is coming from the engine.I have also just checked the plugs and they are all a nice tan brown colour too.Anyone have any suggestions on where the hell this blue smoke is coming from?

james@cjperformance Posted June 15, 2011 Share Posted June 15, 2011 if the seals went on your last tubby dude it is more than likely oil still left in the exhaust, give it a good run and see how you get on. Quote Link to post Share on other sites

mrkd5916 Posted June 15, 2011 Share Posted June 15, 2011 Doesnt the headgasket only seperate the water ways, not oil.i think its both, but it can cause a miss fire and smoke Quote Link to post Share on other sites
Hou Posted June 16, 2011 Share Posted June 16, 2011 The HG seperates both the oil, water and cylinders, hence how when the HG goes you get oil in your water or vise vera = mayo! Quote Link to post Share on other sites
Socks Posted June 16, 2011 Share Posted June 16, 2011 if it was headgasket it wud be between a cylinder and oil way... to cause smoking...but it'd pressurise the oil system...so if there isnt oil being spat out breather into catch tank or pushing the dipstick out....then it aint that...

mech5107 Posted June 16, 2011 Share Posted June 16, 2011 Check compression on all cylinders. If it was only the exhaust, i could say that there is alot of oil still in the exhaust, propably soaked the flexi pipe. Quote Link to post Share on other sites
Taggy Posted June 16, 2011 Author Share Posted June 16, 2011 Problem solved!!Ran the car with the exhuast off and no smoke, exxhuast on loads of it. Turns out my backbox is holding all that oil that poured into my exhuast, over a litre of it!!phew!!Check compression on all cylinders. If it was only the exhaust, i could say that there is alot of oil still in the exhaust, propably soaked the flexi pipe. Quote Link to post Share on other sites
