Oil Pump

Go to atlantic british and buy the pump gears. It will cost you around $100. Its what actually breaks you dont need the whole pump cover/timing cover which is about $600. Just drop in the new gears and re assemble.

Thanks 94Svt50...I'll give it a shot.

How mechanical are you? At your mileage, you should also consider replacing the timing chain and even the water pump at the same time.
