Hello everyone,
i have had a porblem with my secondary air supply to the exhuast (i drive a 1985 ram 50 sport 2.0 L). it is the partthat comes out of the air cleaner and goes into the exhaust. anyway it ws rusted through so i sawed out the rusted part and used a piece of rubber tube (same tube that goes from the air cleaner to the air supply) and some clamps to bridge the gap. that worked for a couple days until it blew apart and the exhaust heat melted the insulation off a bunch of wires. so out of desperation i just clamped shut the pipe. will this be a problem? im not sure what the part does other than supply extra oxygen to the exhuast and if it will negatively impact my car to have it shut. any help is really appreciated. thanks a lot.

huh?

What you describe sounds like the heat stove - it's sole purpose is to bring warm air off of the exhaust manifold into the intake to warm the engine up faster and prevent the carb from freezing up. You don't need it, but you'll need to warm the truck up a lot more before driving on cold days.

 

I agree with what horatio102 said. I would add though, if it is the heat stove, it shoudln't have "blown apart"a rubber tube. It sounds like there is a large exhaust leak there somewhere. I belive it should be more of a wafting heat off the heat shield; not blowing.
