Hope i helped a bit!
Thanks for the reply. My car is not a turbo and I understand what you are saying about the ticking of the cooling exhaust on shutdown. My issue is not those. I usually do let it idle a min. or so before shutdown. I am wondering why the clunk with the clutch pedal not pressed and no clunk when it is pressed in on shutdown. I have heard of thers with this issue I wonder if it is all 6 spds and is normal? I only run 93 octane. It dosen't sound good. Thanks.
