The machinist mentioned that there appeared to be some sort of "baffle" located inside the block right next to where the fuel pump operating lever hits the cam. Apparently this baffle prevents oil from sloshing all over the fuel pump lever. Held in by two bolts from the inside he thought. Any ideas if this is true and if so, anyone know what the baffle looks like? Mine's missing. | | |

Also there should be a similar tin splash guard where the road draft tube goes in, I think, been some time since I've been inside one. What year is your motor? If it's the late style with BIG 1/2" pipe thread oil holes on manifold side, make sure you check to see if the OIL PLUG is pushed in for full pressure. If you have smaller oil holes not a big deal.
If you have the BIG oil line holes and plug is pushed in YOU MUST RUN A FILTER WITH BIG LINES. | | |

It is held in place by what looks like spiral push pins for lack of a better name. Almost like a 6/32 screw size miniature easy out Regards | | |

The screws go in from the outside of the block and into the plate on the inside of the block.This is on my 1954 261, hope this helps. 1951 3100 Chevrolet1951 Chevrolet Suburban CarryallImage"A house is built with boards and beams.

Bowtie, that plate kinda looks like what I would think would go inside the block. I just got the block back and will be taking it to my garage on Thursday. I'll take some pics of the area that I'm talking about and post them. Maybe with the crankshaft pointing up, I can also see just how the draft tube fits in and what baffling (same as this subject) is or isn't there. Steve, is the plate you are referring to located in such a way that it prevents oil sloshing towards the fuel pump. I know that when I installed my double acting pump a while back, I used gasket cement but after a while, oil was visible around the base of the pump. Not sure if thats a factor, but possibly could be. | | |
