What's this part?

[Dartndude73]

I got to a stopping point on my build. Doing some clean up I found this part stuck in a fold of a box under the old balancer. Yikes!@#$#$%!!!!
I see no mention of anything other than the timing chain cover, gasket, seal and balancer in any of my manuals. I've already installed the tc cover, water pump, oil pan and balancer.

With the keyway cut in the part it must go on the crank presumably inside the TC cover. So what is it? What's it do?

Oil slinger washer..

Yep, to keep the oil off the seal and splash it back to the crank, you can live without it but it really is supposed to be there...

Goes on the crank shaft towards the timing cover.

Thanks guys. Looks like I need to order some gaskets. Time for a redo. Man I hate doing things over. Glad I found it though. Would have never known any better if I hadn't checked the box before I tossed it.

If the engine is already together just leave it out . I have run engines without them with no negative effects . Besides you are most likely running a steel sprocket now not a plastic one . Which might be the reason they ran them from the factory.

A large number never came with them to begin with.

2nd-ed or 3rd-ed or whatever.

Im going to send it without the slinger. Part of my weight reduction plan.
