Default Lifter Valley Screen Kits??

I am wondering how many guys run the screen kits and if there is any draw backs to it? Do they hold back too much oil in the valley or do they limit oil drip on the cam?? Anything that might cause a problem that anyone can think of?

Thanks!
Dick

don't think they hold back much oil at all, I do not run them in my boat, but I do in my top sportsman race car, but we run much more aggressive cam/springs and are more prone to breakage compaired to the much milder boat cams...Rob

I Bought some pick ups from theses guys and they sent an info pack that included some research they did on the subject. I no longer have it handy but I recall they made a strong argument against them.

Might want to contact them on the subject.

I run screen kits in the marine engine packages. I use a courser screen the the Moroso kit, only to allow more oil back faster.

Had them installed in my 500s when rebuilt on the advise of my builder. He has a long history with race engines and highly advised installing them. Never a problem and always a little insurance policy. Do the magnets as well, they do pick up chit over a seasons running.

Oh hell, I am just jealous that because I run Fords, This would be a totally one-off custom fabrication instead of an off the shelf part like you guys have access to.

2112,
I took a look at the Titan web site. They recommend not using the screen for reasons of drain back restrictions.. interesting. Thanks for the tip.. I may call them and see what they say.

I guess my concern is, where does the cam and lifter wheels get there lubrication from?? Say the wheel surface is destroyed but the bearing the wheel rides on is ok.. Is there suppose to be a supply of oil that gets between the two (cam lobe and wheel) to protect it??
Thanks!
Dick

I think a point to be brought out would be what type of cam we are running. I feel safe to assume roller, but hydraulic or solid seems to be a huge difference. Obviously, a hydraulic doesnt not see the severity of use, simply by spring pressure, that a solid would see. That has to be a hell of a squeeze when the roller goes over the nose of a solid cam with 600-700 lbs on it, not to mention some 6000 times a minute.

I for one am thinking the extra oil those screens hold back, even if just a little, can only help lifter and cam life.
