Oldsmobile 555137 Pan Assembly, Oil

To get rid of and introduce various engines, e.g. the 350 Buick Engines, 231 and 252 Buick Engines, 305 and 350 Chevrolet-Built Engines, 265 and 301 Pontiac-Built Engines, a person should do as follows: First remove the battery ground cable, then remove any necessary items like fan shrouds, air cleaners and exhaust pipes, after which lift up the vehicle, drain the oil off it, detach engine mounts, support the engine with appropriate means for instance jacks or chains from an overhead crane if need be and at last but one stage in the process take off oil pan by unscrewing bolts after that clean both flanges and put new gasket or gasket covered in sealant. Finally tighten them down to specification using torque wrenches.

Raise the engine approximately 4 inches, supporting it with a hoist, and insert 2-inch blocks of wood under the engine mounts.

Finally, install the oil pan and pan bolts, torque-tightening them to specifications.

Inspect the pan clearance before beginning.

Lift the pan into position and install all bolts finger-tight, tightening the end bolts first. Lower the engine onto its mounts and install the through bolts, torque-tightening them to specifications.

Remove the oil pan attaching bolts and the oil pan itself.

Drain the engine oil into a suitable container.
