Small leak at cyinder to head
 

My 1973 engine has a small leak at the top of the cylinder and the head.
I can see the black stain there and think to hear it. Still runs perfect, also on idle.
Question:
Did anyone tried to put a little aluminum or copper powder into the intake of the effected cylinder - while engine is running. Those tiny particles might seal the tiny leak.

thanks, harold

Have you checked to see if your head studs are too loose? I would check that before you dump copper in your intake runner.

Ummmmmm, I don't think the particle plan is a good choice....

cheers

Powered aluminum & fire don't mix.....well actually they do.... rapidly.:eek:
