I haven't paid much attention to the right side of engine so this may be there. The pipe I'm talking about has a large fitting that screws directly into the top rear of the left cast iron exhaust manifold, the other end has fitting that screws directly into intake at left front behind computer temperature sensor. The pipe itself is over an inch in diameter and is braided material like stuff that seems soft to squeeze like the actual metal tube must be smaller and the outside is some type of insulation..
It doesn't make sense to me to feed unmetered exhaust gases into the intake.
Can you post pictures? What's a "computer temperature sensor"?
