Chevrolet Big Block Oil Pan
|
13. Stef's Fabrication Specialties crafted the 14-quart, kick-out-style oil pan from 0.090-inch-thick aluminum that we'll use to seal up the bottom end of this motor. The pan features a Teflon-coated, uni-directional windscreen, designed to allow oil to flow into the sump area but not splash back up out of it toward the crankshaft. The pan also contains a pair of trap doors that keep the oil in the sump area during hard acceleration. A generous amount of gray silicone sealant was used to mate the oil pan to the block, rather than a traditional gasket. Care was taken, here, to make sure not only that oil wouldn't leak out but that the crankcase was completely sealed off to allow the vacuum pump to do its job. View Related Article
