For pushrod oiling? They are supposed to pressure lube the roller bearing as well but the location of the oil hole concerns me as it doesn't meet with the oil band or oil galley. I can't find a single review of these things. I plan to use them on my very mild hydraulic roller cam, .285 lobe lift, because I'm sick and tired of the noisy hydraulics. Thing sounds like an old chevy with a wiped cam lobe at times.
Edit: These are the Endure-X solid rollers.

If the oil hole for the pushrod lined up with the oil gallery, it would flood the top end.
On that lifter, the oil feed hole is parallel to the axel, and above the oil band.
The oil has to squeeze between the lifter body and the lifter bore to get from the oil band into the feed hole.
That is the normal solid roller lifter “edge orifice oiling” set up.
On OE SBM LA blocks, you have to be aware that there can be an issue with lifters that have an oil band, that the oil band can start to become exposed near full lift on blocks that have lifter bosses that have excessively deep counter bores.

Thank you, I wasn't sure why the oil hole was positioned there. I know about the oil band being exposed and I will check that, but I'm hoping it won't be a problem with the small lobe lift.
