Before beginning a head gasket replacement on a customer's 1979 Perkins 4.236.

After draining coolant, removing the intake manifold, injectors, fuel filter assembly, and valve cover. This is about the halfway point before removing the cylinder head to change the head gasket. Exhaust manifold, fuel lines, rocker assembly, and pushrods, still need to be removed.

Cylinder head removed, and we just inspect and prepare for reseating the cylinder head.

Block is getting cleaned for the new gasket. Those two cylinders being pointed at had a scratch or two that the customer needed to be informed of.

New head gasket in place. Now to seat the cylinder head.

Began reassembling the engine.

Engine has been fully assembled, ran, and then primed, and painted to prevent rust.

Air filter setup in this photo is a temporary, as the new one for the original system was a special order.
