My engine is knocking at idle. And it is getting louder with each autocross!

It appears to be coming from cylinder number three. The engine idles and there is no smoke in the exhaust.

At higher RPM’s there is a loss of power and it is running rougher. I don’t think it is a carburetor or ignition problem.

Is it cylinder or bearing knock?

Is it time to rebuild?

Hmmm?

I'll give you three choices....

Valve seat,

Piston slap,

or a rod getting ready to break.

Of the three, the piston slap is not as catastrophic as the other two.

Feeling lucky?
