If you are committed to a ground-up engine rebuild, then you will no doubt wish to give close attention to the oil-pump. It only takes one small component in the oil-pump assembly to fail and all that good (expensive!) engine work may all have been in vain.
Now that we have your attention, this is one of a number of components that will require careful examination to ensure that it is up to the task of supplying cooling, lubricating life blood (oil) to the hard working areas of the engine.
