My Lazer has 2 annoying minor leaks... The first is the hydro reservoir cap, it seems to always have a buildup of oil around the top of the reservoir, although the level of oil in the tank never seems to decrease. Next is the oil change nut (Kohler 25) mine has the right angle tube , to facilitate changing the oil. Recently (2 months), after being parked I noticed a few drops of oil on the cap and on the floor beneath it. There has been a very subtle decrease in the engine oil level. Is this something that can be corrected with new caps? Thanks.
