Newbie DIYer question...
Please bare with my ignorance, but this is making me a little crazy and I have no one else to ask.
On the driver side of my engine, on the valve cover, closer to the front of the engine compartment is a relatively thin metal tub the comes out of a cap. It goes straight up for about three inches, then 90 degree angle toward driver for an inch the 90 degree angle for a few inches pointing toward the carb. It has no hose attached to it and when the car is running it is has suction.
What is it? should it have a hose attached to it.
Be gentle. :o

My 79 has one something like that on the right side. It doesn't sound as long but it's a breather tube that attaches to the stock air filter housing. I've never tried it but are the valve covers interchangeable from L to R?
Don't feel bad about asking ANY questions here. Some of our cars were owned by Bubba and it's hard to tell what is SUPPOSED to be on the car.

Sounds like the air inlet tube for the PCV (Positive Crankcase Ventilation) system, on your other valve cover there should be a PCV valve which sucks air into the carb. I think the tube you have is supposed to hooked to the underside of the air filter base. You can buy a breather to stick in valve cover if the orig air cleaner is gone and you to not have a provision for the tube to connect to. What every you do make sure something covers that tube so you are not sucking dirt into the eng.
