Oil to the top bearing.....its in the hose, but not flowing much?

[WATERWINGS]

I have oil in the hose going to the top bearing, but it doesn't seem to be moving up like I thought it should.

Should it be a flow, or is it a mist going up there?

I have pockets of oil in the tube, that seem to not move much.

I tested all the barbs and the check valves are doing what they are supposed to.

I change those check valves out in EVERY motor I build these days, just cheap insurance.. The oil in that line should be pulsing and have a slow movement upward to the top bearing. Easy way to check . Remove the line from the top and blow on the hose going to the lower check , it should not allow pressure to enter the hose but you can draw oil through the line by sucking on it. Next attach the hose to the top it should "check" the other way. You should be able to blow through the upper line attached to the check but get a seal when you suck on the line.

Hope that helps,

A little goes a long way. It is not a steady stream of oil it is just the excess from lower main that gets pulsed up to the top. There is no pump so what you're seeing is normal. The tube might fill up in the lower part over time because of the two check valves trapping it. If you remove the line from the top you should see a fine mist when the engine is running and that is adequate.

The big concern in my mind is if it actually does fill up quickly and pump a lot of oil. That would be an indication of a very rich running engine.

I never worried about it until I started using clear Tygon tubing and could actually see it.

Steve that Tygon tubing is the cats meow!! I have been using it for some time now but I use the yellow transparent. It matches my engine and boat

Bud where did you get the yellow tubing? When replacing them do you need to prime them before installing them?

I buy it from these guys. http://www.usplastic.com/catalog/ite...3487&catid=864

They require a 10' Minimum. As far as priming that depends on your situation. Replacement or fresh rebuild. I prime it slightely for replacement but for a rebuild I already have everything properly lubed so when the engine fires there's enough lubrication to satisfy everything untill the system starts operating.

I get mine at the local motor sports store in the parts department.

That is a great site HStream1.I just clicked on the live chat and they told me to come back tomorrow,or call tomorrow and they will answer any question about tygon or any fuel lines. They are in Ohio.

Another source for the TYGON is Mcmaster-Carr ( www.mcmaster.com ) their part number 5552K23 and is sold by the FT. I buy 50 ft rolls but I use the heck out of it. I even tube up the Pro Max and lazzer and motors with it , each one of those engines take at least 5' of hose...I've always said if Mcmaster - Carr ain't got it you don't need it.. Their catalog has 3550 pages...

The barbs, (check valves) both work like they should, and the oil will move up some, but not like I thought it should.

Giving it more RPM's doesn't make it go up any faster, actually it looks like it goes up better when it is at a dead idle.

What gives the pressure to make the oil flow?

I may pull the top hose off and see if I get a "mist" soming out the hose. (I assume a few seconds wont hurt anything?)

[sschefer]

Those uppers are rollers and require very little oil. The amount that will mist out is more than enough. If you think about it, the mix at 40 or 50 to 1 should never produce a stream of oil. That would mean you have pooling in the bottom end from a super rich motor. If you open a motor up that's running good you'll find just a thin film of oil throughout.
