Knock at cold start 700

It's called piston slap, and it's nothing to worry about. It happens when the piston rocks in it's bore bacause it's cold and hasn't expanded yet. My 91 245 has a loud case of it. I think Volvo solved the problem in 93 when they used longer pistons, my 94 940T is slap free.
