A suggestion for the dipstick:
Get a 3” flange from acs, cut a three inch hole in the plenum,and rivet the flange under your plenum directly over the dipstick.
Remove dipstick assembly from engine. Make a “donut” from.032 or .040. ID the same as the dipstick tube thread. OD about 4”, you may have to trim in spots. Now get a piece of 3” scat about two or three inches longer the you need and fasten it to the flange with a hose clamp. Now when you put the lid on the 3” scat hose will seal against the donut. You may need to remove a bit of the spring to get it to seal. 1000 hours and counting.
