I have a 1981 FJ 40 F2 engine. Never touched. Barn find. I took all the usual precautions. Lubed cylinders. Changed fluids. Rebuilt factory carb.
Fired her up. After 15 years in a Montana barn... she’s alive!
Please listen to the sound on my video. I am familiar with the normal valve noise of an F2. I don’t know what this knocking noise is??? Scoped upper, lower, front and rear. Nothing unusual listening to scope. It sounds more ‘upper’ engine just listening.
Stuck push rod?? Valve adjust lash?
The old owner said it was not knocking when he put it up. Very honest old man said he simply stopped driving it.
Any ideas on where this noise is coming from?
I’m afraid to run it too long.
Thanks! JD
