Iv been getting a blowing noise on start up which seems to dissapear after a few minutes. Symptoms sounds like the manifold and I had the car on ramps today to check the rest of the system which seems ok, although difficult to check the downpipe.
If the manifold is at fault, is it worth getting fixed or replaced? the leak seems to seal itself up when hot. It looks like a fair bit of work, any ideas on how long it would take to do and whats involved?
thanks in advance
