I want to build an oil tank, but I don't know what the lines do inside of tank. I've been told that the return line needs to be closed at the top and drilled in the side, etc.

I hope someone can help. A picture would be great. Thanks.

you need a "t" at the return into the tank

I've made several and if I recall the dimensions correctly

the ID of both the hole to the tank and that of the feed to the rocker

should be 0.125"

or you can skip that using a full size return as the 5/16" ID hose will allow considering it must fit a steel tube/pipe

and pressure oil the rockers from the timing cover, where the oil pressure switch goes

a good starting point regarding orifice or jet size at that point is 0.020"

confirm adequate lubrication to the rockers by visual inspection

if you are doubtful as to what they should look like

compare to a know good functioning stocker

but if it smokes pretty much whenever you start it.......... and your valve guides/stems are indeed good

you are over oiling

I have some of my stainless t's already made up if you do not want to go to the trouble of making one

tigging that 3/16" od bar with a 1/8" hole in it isn't for everyone

I did a batch of them so if building a custom brit bike

you could use any oil tank and not have to fret about rocker oiling unless they were doing something silly with tank location or level

and a guy doing something like that needs to be smart enough to figure out how to oil his rockers

whatever you do

don't make it out of aluminum

they tend to collaspe and let go of the hoses

It's all made of steel. What I wasn't 100% clear on was how much the return line need to be restricted to force the oil to the rockers.

It was until it was already done that I found out that Rask makes an in-line restrictor that does the work for you.

Thanks!

full flow available to the rocker lines restriction

then restrict the actual return to the tank AFTER the rocker box feed
