Why do some XR6-T engines suffer oil pump failure? Does Atomic have a fix?
Oil pumps fail in turbo engines (mainly manual transmission cars) due to torsional vibrations of the crankshaft being transferred to the oil pump gears, which are driven directly off the front of the crankshaft. The Original equipment (OE) gears are made from powdered metal and lack the ability to withstand the additional torsional moments generated by high horsepower engines. Hydraulic pressure also splits the oil pump housings open when engines are revved beyond the standard rev limit. We have two fixes for the problem: 1. #306100 Hi-Mass harmonic balancers absorb more damaging torsional vibration therefore reducing harmonics transmitted to the oil pump gears. 2. #306751 billet gear oil pump. Our gears are made from EN-26 steel, heat treated and black oxide coated for both durability and appearance and are virtually indestructible. The oil pump also has a high flow pressure bypass circuit to ensure oil pressure is maintained at the correct levels, irrespective of RPM. The pump is a b
