Does anyone have any step-by-step procedure for changing the EGR heat shield on an early L98? Any help would be greatlt appreciated.

Hi

Are we talking about the foil covered "cloth" around the tube?

If so, I had a bad experience with the replacement covers on the market. They use Velcro to complete the closure.

Velcro went up in smoke! Bought a whole new tube with EGR valve/motor and shiny foil for about fifty bucks at dealer, try CARFAN18.

If it's a real early L98, they used compressible rings to connect them. These are difficult to get off and nearly impossible to get on.

Later models used Torx bolts...soak them well with a "nutbuster" at least overnight.

1. Tear off the old crap.
2. Rewrap with reflective AL A/C duct tape.

I did this as a temp measure, but it works very well. I can touch the EGR pipe after the car has been running.
