8n valve rattle bad

fordtractorpro · Nov 13, 2012

I bought a 8n non runner. Hope it ran,it had 45 lbs of oil pressure cranking. I got to messing with it today. Replaced the carb and some priming up and running. Problem i encountered was the WORST valve rattle i have ever encountered. Beside pulling head and doing the obvious anyone think a valve lash adjustment might cure it ?

Maybe - if it has adjustabe lifters.

Might help IF it has the adjustable lifters installed. Also might not be valve rattle. Might do a compression test before removing the head.

fordtractorpro ,Pull the covers off the side for a look see.Roll it over and look for sticking valves,excessive valve stem clearance.If you still don't see the problem,then start it up and listen with the covers removed.

No personal experience, but a worn cam gear will cause a rattle, or so I've been told.
