there is white smoke coming from the exhaust and oil seeping from where the t2 mates to the manifold by the waste gate arm. i blew the head gasket a while ago, but i got the head skimmed, and i cant see how i done any thing wrong in the process, and it had been about 400 miles of perfect motoring since, and the the smoke started coming from the exhaust one afternoon, i waited for it to warm up then i was pulling out of my drive slowly, then the smoke started coming out quite a lot. i have checked for play in the turbo shaft (none) i have cannot see that the oil and water have mixed either. so i am absolutely baffled, so i anyone can think of anything can you please help me out. its doing my head in, and i dont want to drive it at all while this is happening, even though there is difference in engine sound or the way it drives at all with this problem!!

so if any one can think of any thing, please help me out guys. Kev. Thanks
