Oil Pan

P/N 12557558

• Four-quart pan used on ZZ4 crate engines and 1986-1992 Camaro and Firebird
• Internal baffling and right hand dipstick
• Designed for 1-piece rear main and 1-piece oil pan gasket
• Fits with crankshaft seal adapter P/N 10051118 (discontinued)

It's important to note that Chevrolet V-8 and V-6 engines were redesigned in 1986 to include a one-piece rear main seal. That change required a correspondingly new oil pan design. For pre-1986 engines, there is a newer one-piece pan gasket available. Oil pans and gaskets are not interchangeable between early and late design engines. Blocks that have been machined for a one-piece real main seal require seal adapter P/N 10051118 and must use the newer-style oil pan and gasket.
