Valve cover help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does the passenger side valve cover just have one hole for the hose that goes to the carburetor air cleaner spacer? This is on a 72 k10 with A/C, PS,PB. And also ,how is the driver side oil fill tube bolted down. Just a single bolt that bolts the intake down or does that bolt have double threads which are smaller at the top with a nut to hold down the oil fill tube? When I tore my motor down in the middle of the intake it had one of those double threaded bolts with nothing on it.Hope this makes sense. Thanks

I looked at mine. It is a c10 w/350 engine. It is original & has never had any work on the engine. The pass. side valve cover has the hose going to the air cleaner & also has a rubber plug type oil cap on the forward section. The oil fill tube on the drivers side is held down with a nut on a piggyback bolt.

I just removed the oil fill tube on my 71 C 20. Original engine, no piggy back bolt on mine ? Almost certain it was never tampered with. 52K.

In the assembly prosses the intake is bolted on way before the valve covers. After the engine is painted all of the dress parts are installed. I.E. Fan, Carb, Alt. and brackets, Power steering pump and brackets and oil fill tube. So there would need to be a stud end bolt for the oil fill tube.

Bigbird that does make sense.

The valve covers are identical, with a large hole for the oil fillers and a smaller hole for the vent tubes and the drivers side having two tabs tacked on the carburetor side for the green temperature sender wire.

The oil filler tube should be attached with a stud bolt similar to this.

Di you know if the oil fill tube rubber cap is the same cap as the passenger side valve cover block off oil fill cap? Still cleaning the passenger side cover and the cap is hard as a rock,but sure looks the same.
