Complete Rebuild - EC250

[5valve]

Did you preoil or lube the main cases gasket or did you install it dry?

30hrs after my rebuild, using preoiled gasket, my cases seep gear oil in the upper area, below carb.

I was told to always preoil the gaskets, that seal oil, and haven't had problems till now.


Also, checking prices for seals and bearings, it's insane. I can overhaul whole engine at the cost of $70, shoping locally, as all parts are standard sizes.
Using original parts would also be much cheaper than prices you got, but its probably US EU thing going on.
