Default Oil modes to match the motor application

wrench87 Been running ERsons for 5 years and this is what I have found.
Guys who race and run a .060" oriface are not getting enough oil up top in road racing. The other issues are blueing of the pushrod cup, weaking of the valve springs. noises at idle.
Here's what 15 years has shown me, Have the motor setup right to start. If you are running an FE bottom end of rods and crankshaft run an #80 spring in the oil pump. Also a HV pump. This is hard on the Distributor drive, so it needs to be checked every couple of races. I run 8.5 quarts in the motor oil pan, 1 quart in the lines and cooler and have 3 quarts backup from the accusump. I lost a valve cover gasket that was 15 years old, 2 years ago and was lucky to do no damage to car.
You want the valve covers to be full of oil to the bottom of the intake manifold holes when running. This oil splashes on everything. The most important thing in the head is VALVE SPRINGS. They need to be cooled. They create alot of heat. With pos valve stem seals you will never have an oil problem. If the valve where not straight, machine right, poor machinist assembly, Yes you could have a problem. You are not hurting anything by letting this oil flood the heads. Nascar motors run sprayer bars in their heads to spray oil directly at a certain spot. If you have blue smoke clouds when you start the motor, make hard turns, slam on the brakes, may only come out one side pipe, and it stops after a couple of seconds, your valve stem seals are not doing there job. You are running a PCV valve??
Wrench I have seen alot of motor blowup, break, and seize. I have never seen one break from running too much oil pressure or having too much oil in the heads. I have not written any books but been a mechainic for over 30+ years with all kinds of racing background. I take the best from each and use this in my motors. Just like what is better, Torque or HP. I will take torque any time of HP. My motor will live for many year longer. We are talking about a gas motor not diesel. IMO leave the #80's in the heads and forgetaboutit. Make sure the valve cover gaskets are in good shape and seal well. Rick L. Ps side note. cold start with my motor, 135-138 PSI races in the 75-85 psi. I have lost 3-6% of spring pressure at seat over 12 years of running beehive springs with a 6,200 rpm limit. My lifters act like solids from high pressure. have a .015" depression of the plunger in the lifter body. This way if a miss shift happens, Mr Piston doesn't hit Mr. valve and do alot of damage to Mr. Motor and my pocket to repair. Rick L.
