Intake Valve oilers - Missing
Intake Valve oilers - Missing
Upon disassemly of my heads for inspection, I found that the intake tube oilers are missing. They need to be there, right or wrong?

They are to lubricate the intake valve stem and rocker tip where they meet. Installing a unleaded conversion valve seat and or valve doesn't change where lubricate is needed. Some say its HD's half assed attempt to get oil there , since the exh. is mostly flooded with oil ( low part of the head & where the oil return is located of course ) .Ya have to under stand that there is no oil port to supply oil to the oiler ,just splashing oil, so their thinking is to use it as a some what of a funnel or guide to get the oil there and with that little ball in the oiler to meter or maybe help pump it to that point.

Can't argue with your logic.fourthgear wrote:They are to lubricate the intake valve stem and rocker tip where they meet.

But what I was told is because unleaded fuel has a heat range, or cooler burn, the oiler wasn't needed any longer.
Personally, any slick stuff I can get on any moving part, with any help to get it there can't hurt.

You don't need the oilers if your motor is set up with no-lead valves and stem seals. Don't ask me why, but it is so. I don't have oilers on my Pan heads that Stett built. I don't have them on a set that Accurate Engineering re-manufactured.
The steel ball can get stuck in the tube (although you'd have to run a pretty dirty motor for that to happen. The heads I ran for 35K miles had free-moving balls in tubes, but I guess it could happen).
If the ball gets clogged, the oil drips are diverted to where they don't even hit the top spring collar, much less the split keepers where the oil was designed to drip.

Re:
That is actually not true; there is a small groove inside the rocker bearing(rocker block) to allow oil to flow into the bolt hole; and then the oiler itself has notches on the ID of the hole that goes over the bolt, as well as a small groove to allow the oil out and into the tube.fourthgear wrote: ↑Mon Jan 07, 2008 10:47 pmYa have to under stand that there is no oil port to supply oil to the oiler ,just splashing oil, so their thinking is to use it as a some what of a funnel or guide to get the oil there and with that little ball in the oiler to meter or maybe help pump it to that point.
