I pulled the lower sump off the motor and found a fair bit of sludge and crude on the pan walls, some on the pickup and a bunch on the upper sump
This was what the pan looks like after a quick rinse of degreaser.
Heaps of crude in the upper sump. My engine build has recommended removing as much by hand and then running some diesel oil for a bit to break it down and remove it.
Pickup had a little bot cleaned up relatively quick.
More sludge hiding in a corner
One messy motor, a few more hours of elbow grease and I can start reassembling
