Baffles and prop governor oil line.

The baffles progress.

The part for the rear wall on the LHS of the aircraft reflects the cowl shape of the RV4, but the RHS part has way too much material. I wonder if VANS shipped me the wrong part or if they always do this.

Routing the oil line over the top of the engine appears to be a vast improvement to going underneath. The path is probably slightly shorter, and it is not competing with the electrics for space along the top of the sump. If you do decide to do it this way you will need a 45 degree fitting on the front of the engine.

One issue I am pondering is how to stop the oil line from chafing where it passes through the rear baffle wall. There is no plastic bushing in the VANS catalogue that is big enough.

One of the desiccation plugs started to turn a little pink. I think it must be on the cylinder with the open valve. I took all the plugs out of the engine and regenerated the crystals. They are all a nice shade of mauve once again.
