Just got a tb motor to replace my old one, doing some pre inspections/cleaning etc before dropping it in and resealing most things. I've pulled the inspection plate off the lhs of the block for the water jackets and it's full of crud, not sure what it is? Also there are 3 welch plugs at the bottom that are corroded and need to be replaced. How should I remove them and what size are they?

Better photo hopefully. Also the black stuff almost seems to be oil but it's very dry and chalky feeling

Be carefull knocking the plugs out - as I dropped 2 into the water jacket - pain to get out .

If you have a look - the gullys are connected - not sure why the plugs are fitted?
