Same way with the old post saying someone beat/or ate the "inferior" seats out of their AFR heads in less than 20 hrs yet I have 400 + boosted hours on the "normal" seats in my V-1 AFRS (with tiny touch up vj at every frreshen), I dont always grasp whats going on with these valve train issues, ie, some motors are perfectly fine, others eat the stuff for breakfast, Smitty

I use Jeff Johnson valve covers with oilers,they have a vertical bar in front of the springs. When I moved to the oilers I noticed a rise in temps especially after extended pulls. 6000 rpm range.

Id say that was proof that they cool down the springs, no ?

Yes they do. But like anything else it's more than just adding them. Is your pump capable of handling the extra capacity? Do you have enough sump in your pan for the added volume, also drain back if you rely on stock you will be creating alot more windage. For us it was worth the effort, when we freshened the heads valve spring pressures were spit on.

Ive had em on for a few years now . external pump has more than enough capacity and pan has a full windage tray

Peterson are nice pumps. We run a 4 stage peterson, it allows us to run 10 inches of vacuum.

I only run one stage , I feel so inadequate.

Lol Its a huge upgrade from a wet sump pump. Not only have you reduced the torsional flex on your cam from driving the pump but also reducing load on your timing chain or belt. For anyone not wanting to spend on a full dry sump system, definitely the way to go.

Well the Engine Masters "Tunnel Cram" episode didn't disappoint. I'm really glad they had marine engines in the discussion. Dan, I think you are on to something here.

And the oil filter episode last night was interesting also with Fram gold and Wix racing leading the pac and the little blue guy not far behind
