    Q:
    How to remove and install a front Crankshaft Seal in V8 engine on Chevrolet Impala? Posted by Kolton Z.
    A:
    Remove the crankshaft balancer and note how the seal is installed, ensuring the new one is positioned to the same depth and orientation. Carefully pry the oil seal out of the cover using a seal puller or a large screwdriver, taking care not to damage the crankshaft or distort the cover; wrapping electrician's tape around the screwdriver tip can help prevent damage. If replacing the seal with the timing chain cover removed, support the cover on two blocks of wood and drive the seal out from the backside using a hammer and punch, being cautious not to scratch or distort the area where the seal fits to avoid leaks. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal and install it in the cover with the lip facing inward, using a large socket and hammer to drive it into place, ensuring it enters the bore squarely and stops at the proper depth. Check the surface on the balancer hub where the oil seal rides; if it is grooved, a press-on sleeve may be available to renew the sealing surface, which can be pressed into place with a hammer and a block of wood. Lubricate the balancer hub with clean engine oil and reinstall the crankshaft balancer, completing the installation in reverse order of removal.
