Dear Flame;
Look for oil 'squirting out'. This can happen: (1) shafts upside down, (2) excessive rocker/shaft wear, (3)missing springs, (4)springs reversed, (5) oil line cracked/broken, or installed wrong, (6) Welch plugs leaking (shaft ends),
It's supposed to just drip out @ the bottom & slightly at the top from the oil relief holes in the rockers. Also; it should be running out the oil return in the center @ 5-700 RPM.
Now, when you "rev-it-up" to 1500 there will be an 'increase' in flow, but if you find a squirt the size of a urine stream somewhere, that's no good and your problem.
Good luck, John M......
