Slayer Posted May 9, 2023 Share Posted May 9, 2023 My tt6 is producing a lot of white smoke intermittently from the exhaust pipe, mainly when the car comes to a stop, and only about 5-10 minutes after cold start. It does not do this when the car is moving, and it does not do it at every single traffic light. The car drives perfect and pulling very strong, so no other issue I could actually feel. anyone got any recommendation or suggestion? the mechanic suggested head gasket seal, I saw a post suggesting turbo seal. Just wondering if anyone has seen the same issue? any advice would be most welcomed. thanks Quote Link to comment Share on other sites More sharing options...
bradleyh_15 Posted May 9, 2023 Share Posted May 9, 2023 Either turbo seals or valve stem seals I would suggest. Get a video up. Quote Link to comment Share on other sites More sharing options...
Sukhy Posted May 9, 2023 Share Posted May 9, 2023 Yes sounds like turbo seals to me. Does it also puff out smoke when the turbos are on boost? Quote Link to comment Share on other sites More sharing options...
Scooter Posted May 9, 2023 Share Posted May 9, 2023 Ok this could be nothing but water in the exhaust? Is there a way (park outside on a slope etc etc) that some rain has got down the tailpipe? Only say this as oil burns blue normally and if it's coolant you'll notice that in the expansion tnak/rad very quickly (presuming those levels are all fine) Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 9, 2023 Share Posted May 9, 2023 If it smokes on hot idle its more than likely turbo seals, if it smokes a bit on the first cold start of the day, its more than likely valve stem seals. Nothing Im aware of causes intermittent smoking Quote Link to comment Share on other sites More sharing options...
rider Posted May 9, 2023 Share Posted May 9, 2023 I've have actually seen this happen, invariably on an incline rather than on level ground when a catch can fitted as an aftermarket thought was full to brimming with oil. Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted May 9, 2023 Share Posted May 9, 2023 If you are filling a catch can on a TT6 then you have big problems, engine about to poo itself. Swampy is correct, there are two most common issues on these cars now when it comes to smoking 1 Quote Link to comment Share on other sites More sharing options...
Slayer Posted May 11, 2023 Author Share Posted May 11, 2023 Thanks for sharing all your wisdom on this topic. My car drives fine, it does not smoke on cold start, but more likely on hot idle (but does not do it all the time), so most likely turbo seals. anyone knows the part number of what needs to be replaced ?

Swampy442 Posted May 11, 2023 Share Posted May 11, 2023 You need to get the turbos removed and reconditioned. Quote Link to comment Share on other sites More sharing options...
