Build Time: 0.1 hours ... Analysis Time: 0.0 hours
Removed rocker arms and all eight valve springs to inspect guides. All were where I last left them. Replaced intake valve seal on cyl #2, reassembled rockers, retorqued heads and readjusted valves.
Drained oil and replaced with Valvoline VR1 SAE 50w racing oil.
Installed a section of 2" CAT tubing from the front air inlet (by the prop) back to the oil filter (which has the finned aluminum collar on it). Went for a short test flight, but it was too cool today to tell anything. Oil pressure might be slightly higher with the new oil.
