AntiDrain Check Valves

The bike I am restoring had one of these installed, but the ball was not in it. I do not know if it fell into my crankcase or the previous owner had trouble and removed the ball? Has anyone any comments as to how they work? The last thing I need is to starve my machine of oil! I may well leave it as found, just a hollow piece of aluminum, but they sound like a good idea?

There is no danger to leave the ball out, just normal wet sump that main risk is draining tank to much to start w/o oil flow, but there is a risk just replacing the ball w/o knowing why the last one is absent. Google Norton Commando anti wet sump and enjoy rest of the year studying up on options and opinions both yea and nay. A commando is never really a finished project if actually being used.

Enough said. I read a bit about the Jay Leno valve, more complicated then i want!

They usaualy only wet sump if you don't ride them, in 36 years of owning mine it has never wet sumped at all and it still has the orginal oil pump.

Yes sir Ms ashman, now and then we hear of those who married their childhoor sweetheart and both still really happy about it, so entirely possible just highly unlikely. Here's my start up reasoning after many many oil threads and initial engine run in, it all boils down to minimizing metal-metal contact by First wiping off thin sacraficial layer of nano Zn-Ph pads of ZAPP which only forms on boiling hot surfaces, then rpm should be hi enough fast full oil pressure hits rod shells then the crank splash and head drain down cover cam/lifter with enough oil to surf them and keep it that way long enough to reform the ZAPP layer before shut down.

Natural wet dumping may be a divine intervention of fate after Norton removed the cam oil bath tub in Commando era. Really truly this is my reasoning now and if correct implies saving a few very rare oil seal blow out events ain't worth the accelerated wear on lifters and lobes.

One just never ever knows when some hidden leak develops so its very good displine to always check and Know oil level before taking off. D/t wet sump variations in same bike, I try to pop seat and cap and look in before any settled out to leave me in doubt. Its part of Commando owner ship scope to really fill the tank to top of dip stix marks or amount factory lists and see what's innately the full level. Hehe also ain't had full Commando scope of being w/o a cold start after a good set up - with the cap off to see what's happening at my above cold start rpms. So much oil is pushed back its likely the same start up level of protection of the dry sump valve folks, till they oil pressure hits with about same delay.

Yes.

So, I talked to the fella hat installed the check, and he had no idea where the check ball went, So, it must have passed into the engine! Does this mean it is sitting on top of the oil pump in the line OR am I gonna need to really dig for it?

I don't think it can go anywhere. At least I hope not.

It should have never been able to fall thru it's housing! I suspect it is sitting on top of the gears inside the oil pump? I wonder if it is steel, and if a magnet would pull it out?
