anyone else have a problem with spinning bearings? i first bought my 240 and the motor spun a bearing in a month or so.....then i put a new motor in it.....the same kind as before KA24de and i think its doing it again....anyone else have this problem and maybe know how to keep it from happening.....a teacher at my school said he heard that the 240's have bad oil pressure...

uh not that ive heard of. Maybe the motors you have had have been abused? idk. Ive never heard that problem with the KA's. Everyone ive talked to with KA's in their trucks and 240s and crap say, and i quote "you gotta be dedicated to kill a KA" theyre pretty bulletproof if you take care of em.
