i cant find the hole that connects from the exhaust to the smog pump, my car came without the line so i dont know where its at

my car sounds like a truck


also i hear a knockin sound comin from the TB and my car starts choke up and makes it run like ****, anyone know what it is? [&o]

 

what hole????

 

the one that connects a line from the exhaust to the smog pump

 

there is a tube that runs from the h-pipe to the smog pump tubes next to the head.

 

Its in the back of both cylinder heads. I believe tims 88gt told me it was 5/8's but I think it was 7/16 or 3/8 on my car. In the one hole I ended up screwing a 5/16s screw into the carbon build up because I couldn't get it clean.

 

the fitting on the smog?

 

if they are clean its 5/8 11 thread

 

ok thanks, ill look tomorrow

know this
