desmogging...non-vented cover

Car is desmogged -- in that it's head is plugged and no air pump, etc. It does have charcoal cannisters installed and vented to valve cover.

i'd like to put a non-vented valve cover on with a vented cap (older chrome acquisition). Is this possible? Where would I route the charcoal cannister hose to?

Or should I drill a vent connection into the valve cover?

Thanks

You have several choices. A non-vented cover with a vented cap should work just fine. Use a non-vented cap and you will find oil leaking from every gasket above the oil level because pressure will build in the crankcase. The charcoal cannister uses no hp but if you just want to remove it, you will need to run the bowl vents from your carbs to a safe place. I ran a tube to the passenger side of the engine compartment and down. I could still see if the float stick open without dumping gas on the exhaust. The vent line from the gas tank can be plugged off but you will have to provide another way to pervent a vacumm as the gas is sucked out. A 1/16" hole drilled in the fill nozzel on the outside of the body will handle this, or you could just use the vent line and route it under the car and through a fuel filter to keep the bugs from entering and plugging the line with nests

Lot's of ideas...I'm not ready to chuck to charcoal cans...but from your post, can I simply disconnect the line from the charchoal cans to the valve cover? If the carb bowl vents can go to the outside, can't they just stay connected to the charcoal can? Or does it need to have vacuum?

The thing I do not like about leaving the bowl vents hooked up is that if you have an instance of a float needle sticking open you will be dumping a bunch of gas into the charcoal and down the firewall and inner fender before you know it. Can you imagine dumping raw gas that close to your fusebox? By removing the purge feature you will creat a container that can hold raw gas and without the vacumm to empty the cannister you have removed all usefullness of it, so it may as well be gone. Running a vent line to the ground as I suggested puts the gas away from any ignition source and allows you to instantly know when something is amiss

I removed the cannister and ran gas hose from the carbs down to a point at the left front fender where it would not hit the exhaust pipes. I also drilled a sixteenth hole in my gas filler pipe and removed and plugged the vent pipe at the gas tank like Gerry was talking about and it works great.

Forgot to say I changed valve covers and use a vented valve cover cap.

Speaking of vented caps.I made a non vented cap into a vented one, but wasn't sure it was adequate, so I ordered a Moss plastic vented cap. It has the mesh screen inside it, so it looks vented, and it has the right part number, but I can't blow through the thing. At all. Am I missing something, or is it vented in a weird way that I can't figure out?

While we're talking about that, is there some sort of foam filter up inside the vented caps? I have 69 B with vented cap and found circular hard plastic short tube (inch long maybe) and small circular foam piece sitting between #1 and #2 cylinders when I pulled the valve cover off. Didn't put it back in and it seems to be working fine so far. Vents and doesn't spew.
