Thanks Bruce.

charmaine, since Bruce is satisfied with the quality of the Rover bits, I suggest you get them from him. He has been running a professional mower repair shop for years. That way you know the parts will fit, and you can just get them before you begin the job.

One possibility I haven't mentioned, is that the main problem is not with the gaskets, it is with the quality control on the assembly line: someone may have forgotten to tighten the cylinder head bolts and the crankcase cover attaching bolts. There seemed to be quite a bit of that going on in some Chinese factories a few years ago. Joe Carroll has posted about some Chinese engines of that period not even having the connecting rod bolts tightened, and that tends to end very badly.

It is possible that you can fix your mower just by checking the cylinder head bolts and the crankcase cover bolts with a torque wrench. If you find them to be tightened well below the specified torque, just set them to the correct torque and see if the leaks go away.
