Oil Pan Removal: Notes
1970 Oldsmobile 98 Eng CD TV, Automatic TransSECTION Notes
- 1964 BUICK V6 & 300" V8 ENGINES OIL PAN ASSEMBLY CHANGE NOTE - Oil pan changed in production. Later type has lower oil sump level to improve engine efficiency at high speeds. When installing, pipe and flange assembly and dipstick must also be replaced with new type parts.
- 1964-65 BUICK OIL SEEPAGE AT ENGINE OIL PAN ATTACHING BOLTS CORRECTION (V6 & 300" V8): Some engine oil pan bolt holes are drilled through to crankcase and can allow seepage which may be mistaken for oil pan gasket leak. To correct, remove 3 or 4 bolts in leak area, and if holes are drilled through, apply sealer Gr. 8.800, Part 980032, or equivalent.
- EARLY 1964 CADILLAC OIL PAN SEAL LEAK CORRECTION: On cars before Engine Number 028370, a rear oil pan seal leak may be corrected by installing new oil pan gaskets and a 1/16-1/8" bead of Transmission Oil Cooler Hose Cement, Part No. 1098993, at top corners of oil pan.
- 1965-70 PONTIAC OIL PAN SEEPAGE V8 ENGINES - Even after normal procedures (replacing gaskets, checking bolt torque, etc.) have been followed, oil seepage may occur at the joint where the oil pan side rail gasket over-laps rear pan gasket. Oil pan reinforcement package (Part No. 484083) fits all 1965-70 V8 engines and will correct oil seepage.
