    Upon closer inspection #5 was cracked

      We'll dry sump this M20 next rebuild. Just because. This time we're going with a trap door oil pan. I'll post plans when it's done for anyone to duplicate.

      Remove stock baffle


      Cut off the stock sump


      Fine finish so it sits flat


      CAD the sides and top


      Add baffles

        That motor was pretty short lived!

          Oil starvation will do that

            New custom catch can by Alexander Neumann in Indiana. Dual AN16 with enough venting. He does nice work.

              New rods. Wife ironically says "Those look cost effective"

                I received somewhat similar comments when I installed my piston rings on the dining room table...

                  Cost effective in that they'll help keep your engine in one piece

                    Oil pan is coming along nicely

If that tab is crooked, or raised, then it interferes with the VC sealing. The cover needs very little torque on the nuts to seal. I rub a ~1/32" layer of goop on there too (Right Stuff).
                        Just had to shout out the homie ForcedFirebird for this insight. I pulled my VC on Friday before racing at Homestead and sure enough, my rocker shaft "key" was sitting above the head by a good 2-3mm. Since I didn't want to adjust the rocker shaft positions, I just ground the key down slightly until it sat flush with the head. New gasket with a light skim of Right Stuff on both sides, and the VC did not leak one bit all weekend!

                          Nice. Will be sure to check that.

                            Id be cautious of rivets internally in the pan.

                            I was up above it, Now I'm down in it ~ Entropy - A Build thread.

                              No kidding. They're just temporary. Baffles will all be tig'd into a single unit and rivets drilled out.

                                Got the trap doors and baffles done. A bit more finish work and it goes to the welder this week.

                                This is looking in from the bottom btw.
