Since When Are Timing Covers Not the Same?

Not sure if the installed timing chain is "true" roller, but at least it is not the link chain. I just recently replaced the oil pan, so the oil pan rail gasket did not rip when I removed the timing cover.

I expected the timing belt to be more oily, which makes me wonder if that drilled bolt with the oil hole in the camshaft cover plate was replaced with a regular bolt.

Unless someone objects, I will just replace the timing cover (and water pump, fuel pump gaskets) and close things up again.
