Yeah, that's what I was referring to. Thanks. Where would I even find one of those to buy? Seems like every small block I've taken apart didn't even have one.
That does not "scrape" the chain, it directs the oil that drips out of the hole to fall directly on the timing chain. That is the purpose of having the point of the tab the lowest point on the part. The oil runs down there and drips off.
One version from the factory did not use the oiling tab and left the bolt hole empty, theory is that the oil slinger will also "throw" oil around. I prefer the tab as I feel that it directs the oil better.
