water pump quality from autohauz
I purchased a water pump from ******** for my 92 400E. The sealing surfaces for the 2 paper gasket are as cast. One of the as-cast sealing surface is between the block and pump, the other one is between the top block and the pump. Traditionally, all sealing surface is machined to provide a good flat surface with good surface roughness. Has anybody uses their as-cast seal surface pump and has success?
