Thread: Has anyone experienced this and can validate my theory?

If you would watch the video and tell me if the knocking noise could be an ignition issue. I changed the timing chain tensioner and that made no difference. My theory is that it might be an ignition issue. It hurts me to play this

pull the plugs one by one and see if you can hear the noise go away. Sounds to me like knock more than ignition problems

If that's not rod knock, I'll eat my shoe.

+1 on rod knock.

+9 on rod knock, stop running the motor and there's a chance you can throw bearings in and go. You have to examine the crank and rods though to be sure.....

..............................You are on borrowed time my friend

Those crank journals are out of round if the noise is that loud. No bearing replacement will fix this. It's new motor time. The sooner you accept this the sooner you can move forward.

Throw some gear oil in it for the time being...it will buy you a few extra hundred miles as long as you baby it.

When you said the top end had noise in your post from a few days ago, I sure hope you were not referencing this noise

Nope, it just started yesterday when i ran it for the minute.
