Knocking sound for 10 seconds at startup
Helping a buddy out. Anyone had this issue before? Seems to be coming from towards the rear of the engine.
Length of the knocking varies with the cold weather so quesitoning if it s a oil thing. Checked for loose heat shields, bolts, the usual.

next time its cold, take the inspection plate off the bottom and start the car. just watch the clutch spin until it stops. its possible it could be coming from inside the transmission but i think you would notice something wrong if it were. how heavy of knock sound are we talking here? can you post a video?

Can't listen to the video at work, but I would suspect the turbo control door in the exhaust manifold. If the actuator isn't preloading it slightly it will rattle when the car is cold and shut up once the car warms up and the metal expands.

Had a similar sound years ago when the clutch was depressed. It's possible that the front transmission cover has broken and is rattling around between the throw out bearing and the input shaft.
Jump under the car and open the clutch inspection plate, check to see if the cover has broken off.

Dale's definitely onto it here, it does sound very much like ceramic knocking against cast iron.
