Review on Dorman 565 027 Expansion Plug by Mario Newton

Brass connectors are of acceptable quality considering the price. Be careful though: this kit ONLY includes brass plugs. It does not include screw-in steel oil plugs. The photo is deceptive. I can't comment on their long-term reliability; I am restoring an old Ford IDI diesel engine and rebuilding it to use a conventional freeze plug with this part. I will update as soon as it works for me.
