oil restrictive pushrods

where is a good place to get GOOD oil restrictive pushrods, Hey pontiac man, pontiacs oil the same way as an olds dont they, you ever deal with oil restrictive pushrods, where you get them and what you pay for them,  There is no way in hell im taking in up the rear getting them from mondello or dick miller, I know smith brothers makes some but I dont know how much,  wondering if manley makes some.  

I do not use oil restrictive push rods in any of my engines.

do you have a problem with extended high rpm valve covers filling with oil????

this thread had a cheep solution

seems there are some things to do first..

i wonder...  if you have valve seals that will let you run the valve covers full of oil... and not let oil into the guides...

running the valve cover breathers to some kind of drain back can... that pumps the oil back into the crank case..

i wonder if one of the new style piston style fuel pumps for small block chevys could be used to pump the oil from an external drain back hole and back into the crank case..   keeping the valve covers free of excess oil...

i would think that having a bunch of oil around the valve springs would keep them cooler..  but i could be wrong..


maybe its time to mod a valve cover with a slab of pyrex so you could see inside...    with a tube welded on. that covers part of the pyrex so you could aim a timing light into the valve cover...  so you could get a strobe effect into the valve cover so you could see the oil splashing around in a freeze frame..  

I really dont think the problem is in the heads,  you never hear of someone starving the bottom end on a small block, a SBO has oil drain holes in the valley like a SBC does,  a BBO does not,  just has huge windows on top of the cam, the reason why I ask is there is no reason all that oil has to be pumped up to the heads, especially with roller rockers, im not worried about running the pan dry,  

I like how no one else adds any posts to this, no one disagrees that the oil drain set up in the valley on a BBO is retarded, no one still believes its just in the heads?  

Some marine guys tap the back of their heads for drainback hoses to the pan. Most guys aren't running sustained high RPMs with these engines. From what I have seen at least with Harland Sharp rockers is that the rocker itself slows down oil flow by the way it is routed through the rocker body. This may be why some guys have more trouble with this issue than others, the rocker design influences oil flow, too.  

boy,you guys sure talk about head a lot.

gives me a stiffy  

The only time I've seen a problem with that is when the valve seals have been come apart and partly stopped up the drainbacks in the heads.
