So I ripped my gtb 1756vk off the other day the welds ain't no good got pin holes all around it that let either fuel or oil out of.i just removed the injectors about a week ago n cleaned them using foaming oven cleaner seemed to work pretty good. The injector had no oil on it but looked clean burning.but cylinder number two has a oil film in the manifold n I get a small puff of white smoke on start but the turbo is good no shaft play or even oil on either side just a little that comes out the holes preturbo. The smoke smelled more of raw fuel than oil to me but IDK since the injector clean the puff has almost all gone away but still had some but after seeing the turbo leaking the best day I really didn't get to drive much to see if the cleaning really helped. The inside of the manifold is almost dry at the gasket (no oil) but as it goes back the scrool it thickens going to post pic in profile if I can remember how been a while since she needed help love my alh tdi
