Valve Covers

 
   
 E-Rods takes great pride in offering you some of the hardest to find Chevrolet valve covers around today.  We have taken the time to identify each cover, the years they came on, the years they will fit, and original factory part numbers.

Refurbishment Instructions - Clean with solvent first to get as much dirt and grime off the covers as possible. Beadblast with glass beads to take away the old paint, being careful to not allow bead material to come in contact with the underside of the cover.

1970 Base Valve covers are stamped steel painted Chevrolet Engine Orange. They are held on with hex head bolts and metal tabs that are also painted orange. The valve covers had more rounded covers than later replacements, and original covers do not have spark plug wire brackets welded to them. Stamped steel valve covers do however, have small tabs welded to the side to hold electrical wires. In 1970 small blocks have one tab welded on the passenger side, big blocks have two welded on the passenger side. In 1971 and 1972 all engines with steel valve covers have two tabs welded on the drivers side.  
1970 L46 & LT1
 
The L46 & LT1 engines both have cast aluminum valve covers with longitudinal ribs.  As with the painted steel covers, a vent hose connects the passenger-side valve covers to the air cleaner base and a PCV valve is in the drivers-side valve cover. Aluminum valve covers are retained by silver cadmium-plated, indented hex head bolts. All 1970 valve covers had chrome plated twist-in-style oil fill caps on the drivers side. A large "S" for Stant, the manufacturer of the caps, is stamped into the center rivet.  
1970 Big Block 1970 big block valve covers are plated with low quality chrome. They have internal drippers that are spot welded on and the spot welds show as irregular indents on the outside cover. The passenger and driver-side covers each have two welded-on brackets to hold plastic spark plug wire looms. The rear of the driver-side cover has a large depression to clear the brake booster. This cover is used on both power and non-power brake cars. A foil decal reading "Tonawanda #1 Team" is on the top of the passenger-side cover towards the front. A twist-on style chrome-plated oil fill cap is located on the passenger side.  
1971   1971 and 1972 vettes use a rubber push-in-style oil fill plug that has the word "OIL" molded into the top. Both passenger and driver-side aluminum valve covers are made from the same mold. The only difference between the two is that the drivers-side cover has a hole for the oil fill cap that the passenger side doesn't. On the passenger side, where the hold would go, there is a rigid disc with the crossed flag emblem glued on.  
1971 Big Block 1971  big-block valve covers are the same as those in 1970 except they are painted with Chevrolet Orange paint instead of chrome plating. Also, on the very early 1971's they have the "Tonawanda #1 Team" decals on the valve valve cover. As with the 1971 small-block covers, a rubber push-in style plug with "OIL" molded into the top is used for the oil fill. It is located on the passenger side.  
1972   1971 and 1972 vettes use a rubber push-in-style oil fill plug that has the word "OIL" molded into the top. Both passenger and driver-side aluminum valve covers are made from the same mold. The only difference between the two is that the drivers-side cover has a hole for the oil fill cap that the passenger side doesn't. On the passenger side, where the hold would go, there is a rigid disc with the crossed flag emblem glued on.
