Hey guys, I'm building m,y 500" 440 RB stroker and I'm using the TF 240 heads with the TF .600" roller cam. Upon assembly I've primed the engine to make sure all is well...... The lifter on cyl 1 intake wants to spew oil out from around it like a geyser when it is at the top of the lift. It's the only lifter doing it? I'm using the race hydraulic rollers that hughes sells PN 6074..... I went with these because i heard they were the best.... Any thoughts???? I'm gonna have to remove it to see if there is any difference between it and every other lifter installed. Just wondering if anyone has seen this or is familiar with any pitfalls like this? TIA

I used a set in a 493 build a few years ago. The oil groove that feeds the internals of the lifter extends 0.118" above the top of the oil clearance band on the body. The cam we used was .580" lift and the groove was just at the bottom of the chamfer of the lifter bore at max lift. All 16 leaked. We ended up bushing the lifter bores. They advertise that you don't need bushed lifters......

Sorry to hear of your troubles with the hyd roller!I did'nt go hyd for this reason and went with a comp 829 solid body.Do you use a factory block?Could you tell me the push rod length you use? Factory block and pushrods were 8.9ish on the length? I have the measurement somewhere from when I ordered them....

Does the oil feed hole really extend above the band like in the pic?

Dwayne, I will say Hughes tells me that's not an issue due to lifter only being there for a short time period..... I'm not buying that, what say you????

Do you have the passanger side oil passage restricted to the lifters? Dwayne, I will say Hughes tells me that's not an issue due to lifter only being there for a short time period..... I'm not buying that, what say you????

Yes it does. I have a picture here somewhere of the actual lifters I used. The picture I posted is off Morel's site. This was discussed some time ago on Speedtalk and I think here too. I posted a picture on ST, not sure about here on Moparts.

No, I was told I didn't need to do any mods to run this setup.....

Dwayne, I will say Hughes tells me that's not an issue due to lifter only being there for a short time period..... I'm not buying that, what say you???? Only one way to know for sure. Are these “real” hyd lifters, or limited travel lifters that are basically cushioned solids that are set off of the bottom of the plunger travel? If they’re a “real” hyd lifter that have a pretty normal amount of plunger travel, and you’re going to run them with typical hyd lifter preload, then I probably wouldn’t run them like that, especially if that oil feed hole is extending above the lifter bore. If they’re limited travel lifters that you’re going to set up at something like .010-.020 off the bottom, then I don’t think the leakage will matter at all....... other than whatever affect it has on the oil pressure. The easy test to see if it’s the block or the lifter, just swap in a pair from a different cylinder. The leak either follows the lifter, or stays with the bore.

No, I was told I didn't need to do any mods to run this setup..... I feel your pain. Those are expensive lifters, but like everything in the aftermarket, nothing is plug and play. I check things now I didn't even think about 45 years ago. The block the guy used had a really deep chamfer on the lifter bores, several lifters squirted oil out onto the floor when the pump was spun.

That's what i plan on doing to see where the issue is.... block or lifter.

Cab...... I only saw this one causing the issue. I checked all the others while priming and rotating the crank multiple times.
