Oil Slinger Necessary?

Dear Ron,


All of my Cleveland engine building references include installation of an oil slinger. It is not discussed as an optional part. Although it is a part not commonly available, I would think that in the interest of a long-term leak-free engine front seal, using an oil slinger would be beneficial.

all my Cleveland rebuilds have included a new double roller chain and gear. The gear and chain is too wide for the slinger and it is tossed and had no issues with oil leaks at the seal. If the stock stuff is used I would not assemble it without the slinger just in case.

what can happen oil leaks out through the keyway. when you put the harmonic balancer bolt on, put some silicone on the washer so it seals up there.
otherwise don't stress

So, Derrick, since my new timing chain set is a double roller, you're saying that I wouldn't have been able to use the slinger anyway. I never compare one with the other. I'll have to do that.

I've been driving the car for 8 years without a slinger. So, I guess I'm not too worried about an oil leak, but it did bother me when I saw the step in the engine rebuild manual. I did replace the crank seal to fix an oil leak last year when I replaced the harmonic balancer. I found the area nice and dry when I took the front end off to replace the timing chain set. I think I will seal the balancer bolt when I put it back together.

Thanks for all the help! I'll sleep better tonight.

I don't believe it's necessary. I've seen Ford race engines w/ 700+ HP running 7,000 rpm w/o the slinger, no leaks and no problems.
