Default cant find a bearing that doesnt leak!!!!

i am looking for some input for a front engine replacement, I would like to get more than few gallons before it starts leakn because i am spending more on bearings than the motor is worth. Any bearings out there that wont break the bank but last as long as the motor?

Are you sure it's just not that it's a tad too rich on the bottom? To be honest, the only time I've encountered a leaky front bearing is from a bad LSN tune, not to say that you might have a bad bearing, but if it's a problem some what too often, I would start looking at a different cause....just a thought...

The seal for the front bearing is not in the bearing itself, but in the clearence between crankshaft and engine block. If this clearance is to big your bearings will leak either way you do it.

If you have a "few" gallons between each timem you change your bearing i would say it is pretty normal. remember that you are running a offraod engine with alot of dust. No bearings are compleatly sealed, if they had been, your engine would not perform very good as the friction on the seals would be very high.

best engine bearing you can buy is the 17011 as Huston says. This bearing has doubble seals in the front of the bearing..

17011 from novarossi As Monty suggested,

Or you can try the Reedy one. Even Monty liked that one.

Sorry Monty,

Didn't think about the resistance part though there are many to choose from. LOL. Gues I should have said you liked it a little, though I like the Rossi one a little better.
