Bobby: Do you have concerns that the oil pick up will run dry with a decent? Not sure what you mean by un-porting the pick up.
If the oilpan has 3 Litres (3,17 USA quarts) in after the system and filters are full then the oil pick up will still be covered with a forward angle of 20 degrees.I have made the oilpan a little bit wider to take more oil as there will be always be foaming and delays in gravity free flow back to have 3 Litres of “usable” oil always for the pick up.Yes but there is always the difference between the design and what works.Can always put in 1L more oil at weight penalty of more or less 900 g the “proof is in the pudding” i guess.

Le Roux,

 

I like the idea of keeping the oil pick up inside the pan. Any concerns with un-porting the oil pickup in decent? I’m still not happy with mine and may  build another one.

Hi update on my my sidesump.

Just a couple of holes, then its finnished and in place.

Must still weld in the draining plug and dipstick.

Next is the 4130 chrome moly engine frame.

The “dumy firewall” works good to measure everything, and are on wheels to move around in workshop.
