Camshaft clearance

On the slant 6, the oil pump gear is meshed with the cam shaft in such a way that the drag of the oil pump pulls the cam shaft towards the back of the engine. So no forward camshaft thrust (axial) control is needed; the oil pump drag keeps the cam pulled back. The only thrust control is the back of the camshaft sprocket on the block to keep the drag of the oil pump from pulling the cam backwards into the block.

There is no specification on this clearance; the sprocket just rides on a film of oil against the block. This oil comes from the cam bearing and is spread out by a small notch in the sprocket's back face if I recall.

I guess it could move forward under hard deceleration. But as Badvert65 says, on the street, don't worry about it.

And OP, you English is good; I can't speak Swedish so you are better educated than me!
