I'm having trouble with my radiator drain plug. Concerns my '99 4l v8 p38, bosch engine.
O-ring was squeezing out and thus leaking a bit. Had to drain everything to replace rocker cover gaskets and replace the coolant itself so as the old o-ring was mangled I fit a new one. When tightening the plug it squeezes out again from between rad and plug. Tried three different sizes, all squeeze out:
What am I doing wrong? Or is this normal and is just hand tight 2-3Nm enough for this plug?
It is weird that they would have designed an o-ring seal without recess in the mating faces so I'm thinking about fitting a square section o-ring.
