Hi There,
My GTR has a knock on start-up that only happens when cold for about 1.5 seconds and then stops. No apparent knocks from the engine or deep sounds (when using stethoscope). Doesnt do this when its been run and then stopped.
Sounds like its only happening until oil pressure gets up. Recently changed oil and filter. Engine has 55k miles and running standard boost (currently on standard ECU not fitted the Middlehurst one yet).
No smoke, doesnt use any significant oil, no sounds once running that I can tell...
Ideas? Should I be worried?:nervous:
