You can probably just wash it out with a hose.....but before you do check around the weep holes and see if there is any tracking indicating the seals are seeping. Desert dog is right about the pumps being prone to leaking after they have set for a while even if they didn't leak before.

I did a lot of engine swaps/changeovers back when I was running my shop and usually recommend to my customers that unless the following had just recently been replaced that the water pump and fuel pump be replaced, the alternator pulled apart and the bearings and brushes be checked and the starter brushes checked and the bushings lubed, and possibly rebuilding the carburetor (especially those with fiber floats like Rochesters). Additionally if it was an automatic I'd recommend the front seal be replaced, and if it was a stick, the clutch and throwout bearing be checked. If you capable of doing an engine swap all these operations are within your abilities.

Yeah I had some customers who thought I was just trying to pad the bill, but as I explained to them it was far cheaper to do it when I was doing the engine swap that it would be down the road when they came back for the parts to be replaced in car. Some customers decided to roll the dice and take their chances. For some it paid off but more than a few found out just how aggravating (and expensive) it was to have the car come back once a month or so to have those parts replaced.

Just my 2 cents on your used motor. Unless you personally know the history of it, at a minimum I would check for any seepage at the rear main seal, pull the valve covers and replace the valve seals and pull the timing cover and check the chain. If it still has the nylon upper gear even if it’s in good shape replace it with a new timing set (with metal gears). If the valve seals are hard brittle and broken or if it has a nylon timing gear and the teeth and starting to break off, plan on pulling the oil pan and cleaning or preferably replacing the pickup. If you’ve never seen the crap that builds up in the pickup when a timing gear or valve seals go away this is what you typically find (and this was just valve seals).



I know this is more work and money than you probably want to go thru, but how much work do you want to go thru AFTER the engine is in the vehicle?????
