Smoke Machine to test Headers

[nick_968]

Anyone got the facility to test headers on a car for leaks with a smoke machine or anything else that works? I think I may have a leak that only happens under load and I cant find anything with the car on the ramp at standstill but am getting fumes in the car under load. I dont really want to pull it all off if I can help as its quite time consuming and not 100% sure where its coming from. Any ideas much appreciated.

On the 968, but its turbo charged and running 951 manifolds and crossover, known for leaks and cracks in headers.

Have tried the rag thing, nothing obvious but we didnt hold it for long as not sure if it would do any damage...
