Hi Klaus,

I finally have reached the point in the head gasket replacement where I am trying to line up the marks on the camshaft gears with the fan belt cover gouge outs.

In the picture I have marked the placement of the gougeouts with a red grease pencil on the top of the fan belt cover. This can be clearly seen for the LH gougeout but the RH side is obscured so I have indicated where it is by the yellow arrow. You can see the original white marks made by a previous mechanic on the camshaft gears and you can see that the RH gear mark is not directly beneath the gougeout when the LH mark is correctly beneath the gougeout. I use LH and RH in the port and starboard terminology where there is only one port and one starboard on a vessel/vehicle.

I am following the procedure laid out in the Volvo Owners Club Forum for a cylinder head transplant on a B4204S engine because I am able to print out the pictures and use them when I am out in the garage. There are differences between my engine and this older version but I am hoping the procedure will be fundamentally the same.

We have 'spun' the motor about three times so far using a 30mm socket on the crankshaft and this anomaly remains. Before starting all of this the engine ran fine.
