on a resent ride around oz i noticed that sometimes on starting up my old softail  in the mornings would push the dipstick up out of the oil tank anyone got any ideas why  only does it some times 

thank you mr hoodeng for your reply i have noticed that the oil level in the tank in the mornings is slightly lower when cold  than  after start up and thought that it was leaking into the sump .in terms of ring blowby the engine used 600 mls of oil in 9700km riding hard 2up in hot weather. you mention a possible cause maybe a restricton in the oil tank vent line i will investirgate this possibility a little more. once again thanks for your reply.

pretty fucking hard to do an oil change and filter half way across the barkly

shouldn/t let engine oil go past 4000 klm's max even if you change da oil in da tank on a big run & leave da filter ,  iv'e done that a few time's ,  where's Barkly

4000kms you got money to burn man. you'll wear the threat out on the drain plug .wheres the barkly you need to get more.

Mine is done every 5000kms without fail! Whats $100 for the sake of my engine. I use the Scavenger, and my oil comes out as clean as it goes in!
