oil that "Y"

[ezernut9mm]

what is the purpose of those tubes? it seems like they just redirect a lot of the oil back to the pan. i would like to block them off and keep that oil up top.

The tubes help to ensure that oil gets to the timing gears and distributor gear. People have run without them and with the hole plugged and those components seem to get adequate oil. The distributor gear sill gets a lot of oil from the valley, anyway. Those tubes also prevent the shaft from rotating. If you remove them, you will have to install screws, in their place, a 1/4" tap works to cut the threads, and make sure that the screws engage the shaft to prevent it from rotating. If it rotates, your supply can be completely cut off.

Another thing people do is to pinch the tubes most of the way closed. This will force more of the oil to the rockers, while still providing oil to the timing gears and distributor gear.

Any way you do it, you're not going to keep more oil up top. It will flow to the back of the head, and back to the pan, which is really where it needs to end up because the rocker shafts are the end of the line.

Top oiler kits can be had every once in awhile on Evilbay. I had one on one engine but not certain I can find all the parts for it. some were fancier than others with adjustable needle valve to set exact amountof oil you wanted. As to slinging oil, there should be more than a trickle but less than flowing. The oil passages get clogged from the center cam bearing to the head sometimes. You have to remove the heads to clean all the passages.

As long as each rocker is wet, you should be good.

That's what she said!

What's this Y block thing anyways?

i noticed that the tube went thru the rocker cap and into the rocker shaft. i wondered if that was to keep them from spinning (and to tap into the oil flow to drain it). the drivers side appeared to be home made without the flange to hold it in under the keeper. i see dc sells them and i may buy one to replace it.
it did seem to be oiling pretty good by rich's standards. the push rods were very wet, it just wasn't splashing everywhere like i thought it would.

I bought new shafts from Schumann's Sales. They have grooves across the rocker oil holes to increase oiling.
