Bummer i have been there to and it not a nice place, i am taking my engine out to sell later in the year but guess you want one before then, but i would recomend a rebuild rather than a quick fix 2nd hand engine unless you know the engine. You don't want to get another fleabay engine for a few hundered squid mess about fitting it for it to blow in a couple o weeks when for a few quid more you could have an as new engine.
