Checked the oil pressure sender port and the fuel pump block-off plate. No leaks there. No leaks around the oil filter. Haven't been home yet to check with the UV light. I don't understand why it would leak when pouring cold oil into a cold engine, but doesn't leak under pressure/hot engine. Were not talking a big leak. Less than half an ounce over 3 days.

It dripped when I poured cold/new oil into a cold engine. The oil should go to the top of the head, thru the head drains, into the block around the cylinder or the lifter valley, then down into the pan, right? It should not go to the timing chain area, fuel pump block plate, fuel pressure sending unit. Right?

I guess some could fall from the lifter valley onto the crank, then run forward along the crank to the timing chain area, then out the front seal. Hard to believe it would go that far forward from just pouring it into the valve covers. To my thinking, most likely would be a little draining out of the valve covers and draining down the outside of the motor... but I can't find a leak source/trail.

I'm thinking somewhere a gasket is not quite tight but when the metal heats up, it seals. I was hoping not to have to take off the crank pulley and balancer.
