Pre-oiling
Pre-oiling
Ok, I have more problems with this engine than I think is possible.
Attempting to pre-oil my small block chevy, got a pre-oiling tool installed on to the milodon pump. I spin the pump, its pumping, (oil was coming out of the hole behind the intake manifold at first) so some pressure is building up. However, the heads are not oiling and my electric drill starts to smoke after 20 seconds or so.
Is my drill just junk or is there a problem with my motor?
4qts in the pan.

which hole are you talking about. is it the one for the oil pressure guage or is it the one that is half under the head and half under the intake manifold. when i went to prime my oil system, it wouldn't prime. there was oil all over the ground. it was the hole that was half under the head and intake manifold. i had to take the head and intake manifold off and plug the hole up. i put everything back together and the it would prime.

Clockwise.
It takes more power than most drills can produce to spin an oil pump at any significant RPMs. That's why you burned up your drill. That's also why it's not wise to use a racing pump like that in a motor built to stock clearances and with no modification to the oiling system. It isn't necessary (and therefore you get no benefit from it), and it just wastes a whole bunch of power and creates extra stress and wear on the timing chain and distributor gear.
I agree with ede, all this foolishness about priming an engine is a complete waste of time and effort if the engine is properly built in the first place. The factory doesn't find it necessary, and yet can produce millions of motors each year that last far longer than most rebuilds (primed or not); that should tell you something.
