I decided to address the situation I encountered with my factory oil slinger grinding on my double roller timing chain. No more metal where I don't want it. Hopefully this better design will do the job of throwing more oil on the chain. Feedback appreciated. Anyone interested?

Got to like innovation. Nicely done.
 
I like it!
You asked if anyone is interested which leads me to think you may have some for sale.
How much?
 
Nice work, I like the design of your slinger also. 65'
 
That's very cool. But I've never looked at those as an "oil slinger". IMO, it's more to help keep direct oil off the front crank seal and lessen the chance for leaks. Think about it. WHERE is the oil coming from that it's supposedly supposed to "sling"? The timing chain only gets drip oil from the factory drip tang. That's not enough oil to sling. At least, that's always been my outlook.
 
I'd be cautious of your new slinger fatiguing and developing cracks at the base of the blades, but wow i like the work you have put into it. I have a pretty patented slinger too.

It's really neat to see your idea come to be.
You're a craftsman. Respect to you.

With all these things... I always want to test and solidify what I think I'm learning .
I'd like to see a plexiglas/see through timing cover on a running engine with that in place and and another engine same cover but stock slinger.

Could it be its name has mischaracterised the entirety of it's function, is what I'm getting at.

When I questioned the simplicity of the OEM slinger, I was told too much/fan like would aerate/foam the oil. Good luck with it.
 
Thanks for all the comments. To address your concerns: No clearance problems. The main reason for making it was to address that issue. It is made of stainless and is .020 thicker than the stock one, so fatigue shouldn't be an issue. We even made the area around the keyway thicker to minimize that possibility. The centrifugal force is minimal. Can do an analysis on that using software before we sell any. I don't think there will be enough oil slinging off this thing to cause foaming. I think there might be more oil getting in there from the crank spinning by the number one cap. Just figured it couldn't hurt to improve chain oiling and clearance issues. Blade shape and rotation was designed to direct the oil back at the chain, not at the seal. Guess I will never know if it's the greatest thing since sliced bread, but doubt if it's the worst. It definitely won't gouge out like a spirograph like the original did. Probably sell for $20. Most of the labor is in the deburring from the plasma cutter.
 
Id not put a pitch on those 'blades' it may froth the oil but those are pretty cool.
 
I think the slinger is there to avoid seal leakage as well but its a novel approach to aide in lubricating the chain . I wouldnt be worried about aeration of the oil any more than what the chain itself does .

Yes, oil slinger's main purpose is to keep excess oil off the front seal, a rotating oil shield .

Mainly, with every stop and oil slosh forward it sorta acts as seawall..also concentrating the oil at the crank gear/chain as it drags up.
Theres plenty of oil to the chain and that why I dont drill and plumb for extra oil to it.
 
I have always assumed that there is a hurricane of oil in the crankcase that provides ample oil to the chain . And like Moparofficial said when you decellerate oil will slosh forward and emerse at least part of the chain in oil .
But still a cool invention .
 
What debate? The slinger slings residual oil everywhere, and it keeps the majority of the oil off the front seal by redirecting the flow out, not forward. Put 4 quarts of oil into your oil pan next time you have it off. If you have baffles and a windage tray, your oil is gonna be contained in the sump, no where near the slinger. Here is a pic of a Stealth 3.0 V6 with a FULL fill of oil, notice that is all in the sump and this is not even including the oil that gets pulled up the motor during operation. This applications oil level is no where near the chain and the baffles will most likely control the slosh. Who's got a B that wants to make a plexiglass timing cover? Anyone got a pic of a Mopar V8's actual pan oil level?

Would it be the end of the world if a person left one off?

I dont run one . Had one on my Barracuda 360 and it rattled on initial start up . Made a hideous noise and it tool me a while to figure out what was ! The new balancers snout was a tad short and allowed the slinger to rattle.
 
20X5x8 with an additional 10x3x8 for a total capacity of...800 cid plus 240 cid = ~1040 cid oil capacity. a 5qt jug of oil is about 10x8x4 or 320 cid. About the size of the smaller bottom part of the LA oil pan. Not even close to 1/3 full. slinger extends about 1.5 under the pan rail.......Thats a reach. Many have found no slingers in their motors for various reason with no starvation issues. I think the main reason for it was to keep oil from flooding the main seal . also look at a windage trays depth.

Nope. I don’t use them. And the timing cover seal never leaks. Just some trick of the week to try and stop an oil leak (and the warranty repair because of it) that was an answer for a problem that didn’t really and doesn’t exist today.
