the lt1 water pumps are driven by means of a shaft connected to the cam shaft in a type of way. Â*the hole where that shaft comes through the timing cover can sometimes leak and cause oil damage to the optispark distributor. Â*The electric conversions bolt right into the OEM housings and i think are comparable in cost to a replacement stock lt1 water pump. Â*I just want him to be aware of other options.
