"I wouldn't have either. IF it is torqued to spec. I wouldn't touch it again unless absolutle necessary." yeah, trust me i won't - hopefully it is in there good and will withstand the vibration of the engine. "Looks like the hole that originally was leaking?" yes, the leak was right above this screw... i'm starting to think the guy probably stripped the screw and put some thread lock or something similar on it and just screwed it back in there. after i realized it was stripped i pulled it out and it had what looked like some really lightweight aluminum or aluminum-like substance wrapped in the grooves of the bolt. this of course could be aluminum but seemed to be a little too brittle for engine aluminum. again, this is just a guess. "Now do me a favor and email me what camera you used for the pictures and how you got them from the camera into your post. I think you have my email address." sure thing! i'd be glad to Walt. the camera is a Fuji e510 5 megapixel digital camera that i've been happy with... they should be quite affordable now as i got it for $150 or so after rebate almost a year ago. i'll get that email to you in a bit.

Typically, if the oil filter is optional, they'll show an optional sump and/or OF cover plate. The IPL for your engine shows an OF as "standard"? I'd say get the nipple and install a filter. After a few minutes running, the filter should get hot if the oil is circulating.

IF you have room, you can use one of the longer ones. Might be cheaper too.

I don't know their reasoning, but it may have been to align that part with common oil filters in Japan. Honda motorcycles and other Japanese makes of motorcycles use a metal can with a replaceable filter element. That type has been used for at least since 1970 on 'cycles. Both types filter well. The cartridge type is messier to change, but has the advantage of providing a look inside the filter can to get a view of what has been collecting. I prefer the metal can over a plastic one. In Japan, a number of engine design features were first tried on motorcycle engines before transferring to automotive engines. For example, 4 valves per cylinder first appeared in a motorcycle enigne. Yahama went as far to make a 5 valve cylinder and then settled on 4 valves. The problem of designing machinery to actuate multivalve per cylinder engines was worked out on a motorcycle engine.

Any time you use oil based paint, it must be 70 degrees or higher. Oil based paint takes a long time to dry and even longer to cure. I am curious how humid or damp the room is because the humidity and moisture will affect the drying time. Keep the room warm until the paint cures. Get your second coat on once it is dry enough. Don't wait a week to put your second coat on as the paint will be fairly cured and the surface will have to much sheen to accept the second coat.
