hey i just got an 84 Z28 and i there is no EGR hose or cover on my stock exhaust manifold. is there any benefit to putting the hose on or would it just be easier to cap it off. also where would i be able to get a cap?

thanks in advance for your help,
James

 

Welcome to thirdgen.org.

The EGR isn't attached to the exhaust manifold. It's on the intake manifold.

What you might be referring to is the thermovac hot air system. In cold weather, it will help eliminate an off-idle stumble while the engine is warming up.

 

I'm not sure what you mean. The EGR system runs thru the intake manifold, not the exhaust manifold. Do you mean the AIR pump system? The AIR pump puts fresh air into the exhaust manifolds and the cat thru a system of metal and rubber lines.

 

sorry im still new to this, learing a little everyday. i guess it is the AIR pump. what is the best option i have? just go to NAPA and get the hose to run to the snorkle?

 

i got the hose today but there is still some smoke. it looks like its coming from the valve covers on both sides. should i change the gaskets?

 

The hose to the snorkel is not EGR or A.I.R., it is the thermovac system I mentioned.

If the smoke is being caused by oil leaking from the valve covers onto the exhaust manifolds, then you should change the valve cover gaskets (most likely - they may just be a little loose).

 

You also might want to check if the PCV valve is in good working conditon and not stuck closed.

well the car was sitting for about 10-11 months before i bought it. i got the valve cover gaskets and im going to change them as soon as i get it registered and can bring it to my friends house as he has all the tools i would need for anything.
