I get oil up the dipstick tube at high rpm. I have a 496 chevy (gen 4 stroked). It has a 10 qt pan. I have 8 in th pan and 1 in the filter. Below 3500 rpm it is good to go. If I run above that for a few min, I get oil coming up and out the dipstick tube. Any thoughts will be great!! Thanks in advance!
