Nice work on those screens I need to go smaller mesh to stop needle bearings from getting down to the oil pump ,gear drive or oil pump gear. Anybody run anything with smaller mesh? I figured that it might work to put a finer mesh over the screen in the oil pan, but that might not protect the gear drive? Putting mesh above the roller wheels won't stop the needles from falling out the bottom of the lifter bores, will it I had two Mopar brand solid roller wheels break in half and get the cam, luckily I shut the motor off before sucking any of the needles bearing up into the oil pump

I have a basic concept of securing the screen without screws or epoxy. I'll make a drawing and post it here. With the various blocks (e.g. factory, megablock, KB, and etc.) there are differences in the shape geometry around the drain holes though.

Why bother with valley screens? Put a hydraulic filter strainer on the suction line in the pan and all your issues are solved. Ran my milodon pump that way for 10yrs and the pump was like new inside. you would not believe the amount of damage something like a broken lashcap can do to an engine if you're also running a windage tray. they chip away at your rods leaving potential stress points for a crack to develop into a break. Also broken rocker arms falling into the oil return holes tend to break cams & that in turn does other damage. Valley screens are worthwhile if you're a regular racer.

Thanks id appreciate it, i fabbed up a hold down today like what rebel posted the pics of and received some screen today but haven't started any block mods but im hoping to get the block in this week or next for final machining so I'm trying to dot all my eyes and cross my teessss.

Nice work on those screens I need to go smaller mesh to stop needle bearings from getting down to the oil pump ,gear drive or oil pump gear. Anybody run anything with smaller mesh? I figured that it might work to put a finer mesh over the screen in the oil pan, but that might not protect the gear drive? Putting mesh above the roller wheels won't stop the needles from falling out the bottom of the lifter bores, will it I had two Mopar brand solid roller wheels break in half and get the cam, luckily I shut the motor off before sucking any of the needles bearing up into the oil pump Wont stop the needle bearings, but the screens are a good idea.

I've never broke a rocker that the needle bearings came out(knock on wood) but have had lash caps and broken PRs laying in the valley.. I dont want that trash getting hung up on a cam or have it fall down onto the crank/rods at 8000+ rpm.. that screen has done its job for me a FEW times... the lifters are below the screen so it might not help with them but it does help for stuff up in the heads

Afterr reading Cab's comment about the roller lifters, though I haven't lost any, I may opt for a finer screen in the pan to go over the one that is there. That one though will need to be sized as big as possible and still stop the needles. Anybody know what size roller lifter bearing needles are?

Greg.. myself I wouldnt do that.. if you make that small enough to stop anything that could get there I dont think you would get the flow you would need.. specially on cold oil... JMO.. at some point you just have to take your chances and hope it doesnt happen

I should have clarified in my first post that screens are a good deal Not intending to keep anyone from using it, sorry I've had lash caps and psuhrods drop down into the lifter valley when a valve spring broke

Why not use a bushed roller lifter? Safer & a lot stronger. Personally I don't trust needle bearings at any level https://www.lunatipower.com/News.aspx?id=121

When I bought all my stuff they didnt make the bushed lifters.. if I were buying something now I MIGHT look at them.. but as I said already.. I have never had a needle bearing come apart on me.. been using them for years now

^^ Love you car man.. Thanks DARTH if that thumbs up was for my bucket of bolts... Heres what i came up with using the design rebel posted and I ended up using a 1/4 20 bolts, I had to take it slow drilling the first 1/4 inch making sure it was straight it could of blew out a side every easily as theres only a tad over a 1/4 inch of meat on the rib.
