I have just fitted a hybrid from Wallace Performance to my C20 LET. The reason i upgraded was the standard turbo was smoking bad on idle but when driving all was ok. It was like the seals in the turbo had gone causing (oil smoke) from the exhaust on idle.
So i changed the turbo yesterday and it went straight forward. Warmed it up then went out for a short 5 min run, then back to the house. On idle the turbo started to smoke bad. It was white smoke i think, but it was hard to see as it was dark and the oil smell was back again. It also smokes as the car is moving. Cant see the road behind you! Any ideas on what this is?
