For desmogging a 3FE this aluminum plate is used to cover the opening in the intake manifold. The drain plug has the correct threading to securely screw into the exhaust manifold where the EGR had been plugged in. The allen headed drain plug comes with a copper crush washer.
$30+ shipping.
For comparative purposes a drain plug is shown next to a brass plumbing plug some have used to fill the exhaust manifold. The drain plug seats fully while the plumbing plug only engage a few threads in the manifold.
