Re: Rebuild LQ9 or...Stroke it?
you can thread out all the oil and water plugs...for cleaning the block...and re-use them.
the only cup plug is in the front of block, for one side (oil galley). What I like to do is drive it out from the back with a long piece of rod after you pull the plastic barbell thing from the rear.
This lets you clean the oil galleys good with brushes. You'd want to get a new cup plug to replace that one then.
