Title: Coolant leak into crankcase
Post by: twosmokerider116 on June 17, 2012, 08:11:42 AM

Okay, So I have a coolant leak into the crank case of my 86' Kx500> I changed the water pump seal but where else could the coolant possibly be leaking in from? Its a Lot.

Thanks.

i am sure that the only way coolant can mix with gear oil is past the water pump seal. if you have replaced the seal there are 2 thing i would question. 1st: was the seal put in the right way (easy mistake done it my self). 2nd: what was the condition of the shaft where the seal runs. if the the surface is bad it will ruin the new seal.

If it's in the crank case it might be a head gasket.

Pegger, I think he means the gearbox, if it was a headgasket he would/should know that it is going to smoke white and show a loss in the coolant level. it almost has to be the water pump seal/shaft or both, of course there is the chance the case is cracked in the water pump area but I would find that unlikely.
