I need to get my 2F running before Thanksgiving and I am hearing a bad noise coming from the engine. This is my first time really driving this FJ60 since I bought it. At first I thought it was the valves but after adjusting those I still hear it. It happens only at RPM's above 1000 when acclerating, decelerating and at idle. It is like a clatter tied directly to the rpm's of the engine. I had someone rev the engine while I was down near the flywheel and it sounds like it is coming from the lower part of the engine. At first I thought it could have been the pilot bearing but now I think it is more forward in the engine. Any ideas what it would be? How difficult is it to pull the crankshaft and bearings? I do have another 2F I can pull parts from if needed. I would welcome any ideas.
