Can the front crankshaft oil seal be replaced with the timing gear cover in place, and what steps should be followed for proper installation in four cylinder engine on Chevrolet Astro?

The front crankshaft oil seal is replaceable with the timing gear cover in position but it may be convenient to remove the cover because of the tight clearance. The first is to disconnect the negative terminal on the battery, then to remove the hub of the crankshaft pulley, but before that, one should always disable the anti theft system of the car audio. The installation direction of the seal should be marked, as the new seal must be installed in the same position. As a result, you need to remove the old oil seal carefully with the help of a seal puller or a large screwdriver without distortion of scratches. Before installing the new seal, use clean engine oil or multi-purpose grease on the outer perimeter of the new seal and position it with the lips toward the inside of the cover and with use of a large socket and hammer, pound it to flush with the cover. If the timing gear cover is removed, put it on a flat surface to push out the old seal lest you harm the cover or the seal bore. Before removing the seal subsequently from the cover, it is advisable to use penetrating oil in or on the seal-to-cover joint. Remove any of the old components and corrosive matter inside the bore of the shaft and place the new seal in the appropriate place so that the lip of the seal is towards the center and this must be done gently with the help of oil. Pump the seal into the bore until it is flush with the outer diameter of the bore hole, this can be done by using a socket or any other appropriate tool as use of a hammer may cause the seal to crack. Last but not the least install the timing gear cover back to its position on the vehicle's engine.
