[QUOTE="FIREBALL, post: 16183695, member: 178539"] Good job telling us all youve done to the motor, very impressive. But very hard to tell by listening to the recording. Need better description of what kind of a noise it is---did it sound that way from the beginning, what is the oil pressure, what rpm does it make the noise--like only idle or all the time, have you checked for exhaust leaks, is the engine missing, does it accelerate smoothly, have you done a compression check, did it transfer from one side to another or is it now on both sides? It could be a number of things from a bent valve hitting the piston to a flattened cam lob, a spun rod bearing or a broken piston ring which could have been caused by a bad installation or tolerances/piston clearances too tight. If I was to go by just the sound I hear in the video I would say oil starvation to the top or bottom end which may not be connected to oil pressure but a clogged or blocked oil passage. You better not drive it and have a professional diagnose the problem because anyone here can only guess. [/QUOTE]
