...Less is more. No oil pipes for me. The left side oil cooler line it is. If anybody has a size or part number for the O rings, I’d be much obliged.
With the oil drain tube tucked up between the #2 and #3 header tubes, there is no danger of snagging the tube. In fact, with a 4-1 header and a center merge collector, you will have all 4 header tubes hang lower than the oil drain tube.
I forgot to mention, the left oil cooler line removal for oil drain trick only works with stock FJ oil cooler hard line.
If you have the RPM oil cooler with the Army/Navy fittings, or other aftermarket cooler with AN lines, there is no room between the thicker AN pan fitting and the header tube to pull the oil pan fitting out of the oil pan.
At least, if found this to be true with a 4-1 Kerker header on my old ‘92. I never had a VH header..
