My Mate at home drives a Polo Gti 9n3 (2006), there are some issues now and no one knows what's the problem.
What happens is that once the car is warm it tends to smoke under load a bit and once you rev it. It's white smoke. E.g when he stops at home and rev the car a couple of times white smoke comes from the exhaust.
Everyone told us it's rather valve stem seals, turbo seals or rings? Turbo was replaced with a secondhand turbo about 3 months ago
not sure if its the seals?We checked the car now on cold start up and no smoke came out. But once revved some white smoke comes out again and the car backfires with every blip of the throttle?
If anyone know what this issue might be please help.
