Hi Gents!
Finely done with 74 T500 put about 600 miles on her runs well did Powerdyno a couple weeks ago.
I have been checking the crankcase oil once a week and find its always down just little,had center seals done by Ken O'Connor racing in Ct. Don't have any external leaks is this normal? I do notice a little more smoke than normal but nothing like before replacing seals. Just part of the deal?
Thanks for help!

You say you had the center seals done. Not the outer seals too?
When you rebuilt it did you use proper petrol and oil resistant gasket sealant when bolting the crankcase halves together? (Silicone based sealant will not work). I learnt that one the hard way when I was a kid rebuilding my Dad's MZ 250. Doh. Sorry Dad!
Was there any sign of damage to the mating surfaces and were they scrupulously clean?
