Hi, I hope someone will be able to help me with this.I just bought a 1968 FB that has been in storage for 20 years at an estate sale. It has the 350 2 barrel. Many people had looked at it and played around in the hood during the sale. I bought the car a few months later. The car runs very rich and little rough. Perhpas just some bad gas. I Plan to completely tune it up and rebuild the Carb. Their is an oil cap on the driver side valve cover, but on the passenger side there is just a hole. I looked everywhere looking for a tube and pcv. No where to be found. The air cleaner does not have anywhere for a tube. Completly solid. There is a med tube behind the carb that goes into a plastic spliter. near the valve cover. one deteriorated hose from the split went to a metal tube I think going to the tranny. The other has a tube with a screw shoved in it. (is it possible this plugged tube would somehow go to this valve cover?) It looks to small. I can not find a diagram anywhere. I have a chilton that shows nothing. Auto stores can not help but want to sell me a PCV.
2. I saw a rubber hose hanging from the bottom of the car with a bolt shoved in it and hose clamped. Fuel line hose material. Wondered what the heck it could be. I traced it back and it goes to the fuel pump. I am stumped on this. Fuel pump has a fuel line coming in from tank, A Fuel line to carb, and the this mystery hose with a bolt shoved in it. Any ideas what I should do with this?
If it's a '68 engine, the PCV doesn't mount on the valve cover. The PCV plugs into a rubber grommet in the valley pan under the intake manifold. The hose on the PCV goes to a fitting in the intake.
The hole in the valve cover takes another rubber grommet where a steel vent tube is inserted and the other end of the steel vent tube goes to the passenger side of the air cleaner.
The fuel pump may have two lines going back to the gas tank. The larger one supplies fuel to the engine and the smaller one vents back into the tank. When I bought my car there was a hose on the vent line with a bolt in it. The fuel pump had been replaced with one that did not have any provision for the vent line. I returned it to a stock fuel pump.
If you want to keep it a 2 bbl, I have an air cleaner and the vent tube that I removed from my car and won't be using again.
Now I've got a Q-jet and an open element air cleaner. I put a retro-looking breather in the passenger valve cover.
