I think I have sufficient flow to the top, but I dont know that for sure. I have plenty of oil to the tips of the rockers, but not to the cups. Been asking around and nobody has an answer on how to determine sufficient flow. 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.

I thought of another question. At rest with the motor set to oil the top, should oil be squirting out of the rocker and running down the adjuster to the cup area? As it sits now, with a drill on the pump, plenty of oil is running out of the feed hole for the cup, but none of it hits the adjuster. The tip on the other hand gets plenty of oil. Ive checked it with the motor running and very little to none gets to the cup, tips once again get plenty. 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.

The oil is used to "lube" the adjuster/cup - shouldn't need much. On the other hand, the oil is used to "cool" the spring. The more the better! Stands to reason more should be directed at the rocker tip/spring. Also keep in mind that most of the oiling is achieved with "splash" ... the squirt hits the side of the valve cover and then splashes back onto the cup, etc.. Harland Sharps have no oiling directed at the roller tips or springs. Makes ya wonder !

Plenty of oil coming out of the feed hole for the cup area....none of it gets to the cup...So, ya my mind is made up, not getting any oil to the cup..... And as I said above, motor running or not, no oil gets to the cup..... Further, I have a set of stock adjustables and they get plenty of oil to the cup with the motor running. The oil swirls around the pushrod very nicely. So based on the above, it would appear that I have sufficient volume..since the ductile rockers get plenty of oil. But, how do you KNOW that you have sufficient volume? Ive had 2 other sets of rockers on this motor and neither set had sufficient oil to the cups.... 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.

(some) burn up in street use, while the same setup lasts for ever in race conditions. Id say that with increased engine rpm plenty of oil flying around for the adjusters. But you can look into the hollow adjusters, increase or redirect the size of the oil passage. Ad the banana groove rocker shafts. Take the cam and groove the correct cam bearings, IIRC #4 with a .050x.050 oil groove. You cold drill and tap the blocks valley area and just provide full time oiling that way. A high volume oil pump will provide more oil (everywhere) at idle and just off idle Just some thoughts.

Also you could use your priming tool to spin the pump and watch... turn the crank over slowly while priming it

I already had the grooved shafts, so after putting the hurt to a few of 'em in a fairly short amount of time, we... (a) added "connecting channels" from the rocker arms' main oil groove to the adjuster screw hole to make sure there was no obstruction to flow (b) opended up the feed holes size (wasn't the same size from one rocker to the next w/ the particular brand I had at the time, oddly enough) (c) added some anerobic sealant between the shafts, shims and rocker stands to try and reduce oil seepage from where they mounted on the heads (d) ground small "flat spots" on the tips of the adjuster screws that were used at the time to make sure the screws weren't "point loading" in the bottom of the pushrod cups (later on switched to Smith Bros. adjuster screws which come that way) (e) had the #4 cam journal grooved for full-time oiling to the rockers I can't say exactly what mod was the true "fix", or if it was a combination of them. Regardless, haven't had any problems since doing these mods.

So, my question is, at rest with a drill running the pump, should oil be hitting the adjuster/screw? As it is, no oil hits the screw, just runs down the back of the rocker 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.

As it is, no oil hits the screw, just runs down the back of the rocker See what rpm your spinning the priming tool then you can relate that to the cam speed (1/2 of the crank) but it should be hitting it I would think EDIT better yet just look to see what the pressure is and if its above about 20 it should be hitting it because that would be pretty close for idle Last edited by MR_P_BODY; 12/19/10 01:14 AM.
