@Stan Galat you are correct, thousands of dollars. The pump was $700 and the tank was over $300. Then add all the AN10 and AN8 hoses, breathers, fittings, welding gas, steel, etc., then keep going. I think I'm close to 2k in the "remove oil leaks and make the oil system better" department.
The fact that my engine will always have an immediate supply of oil to the bearings was the whole point, the leak reduction is just a bonus. Hooning makes that a necessity.
But it's cool to not have a dipstick. You merely remove the cap from the tank and look inside. Yup, plenty in there, time to go for a ride.
