Default Exhaust valves

Which Caterpillar Diesel valve will work in a V6? Will it also work in a Magnum?

Have you seen these aftermarket valves on Ebay?

Hope this helps.

Default Re: Exhaust valves

The valves on ebay are for the non Magnum V6 engines, the real problem is in the hollow stem exhaust valves that are filled with sodium. These valves were notorious for snapping when over revving so the solution is to switch to a different type of exhaust valve. You can have custom stainless steel valves done up from Manley. This is something I'm seriously considering for my 478M because I know with my lead foot those exhaust valves will let loose.
