Re: 1983 Chevy I6 Confused.....
Welcome to the board. I believe all that junk is called PAIR - pulse air reaction. It's a sort of passive AIR pump system. All emissions related, of course. These six cylinders were designed long before emissions regs, so all sorts of junk needed to be scabbed on.
Can you take it off? Well, that depends on regulations in your area. Does the engine need all this junk? No. As for the smoke, it's quite possible that oil leaked out from under the valve cover and then rolls down on to the exhaust manifold. These engines tend to leak from both the valve cover and side covers (covering the pushrods).

Re: 1983 Chevy I6 Confused.....
Yep, those two chambers on top of the valve cover are part of the PAIR system. There's a write-up on it and how to ensure it's working in the GM shop manual.
Here's mine. Look quickly, because there's a freshly built 350 in my shop! ![]()

Re: 1983 Chevy I6 Confused.....
Six's were most common in tan and white trucks. Why? 2 reasons one is price leaders at dealerships. white and tan are neutral easier to sell. Top reason is fleets order their trucks as basic as possible ie. cheap. White and tan were the most common fleet colors. company logos always go with white and most go with tan.

Re: 1983 Chevy I6 Confused.....
yes the leak or smoke oil on the exhaust. you cant just yank all that stuff off that varijet has several vacuum lines. I changed carbs and that's not easy. Check local emission laws before remove any thing.

Re: 1983 Chevy I6 Confused.....
My truck was originally (and still is) blue, and it was built with a 250. However, I think the six cylinders were more popular in Canada.
