Did mine today.... although my gasket was in one piece while it was on the housing, it didn't come off that way..more like about 50 pieces. Mine was completey stuck in the housing. I cleaned up the best I could and cleaned underneath the engine, plastic pan, power steering rack and just wiped anythng that had oil on it that I could reach. Next on my list is a cooling system overhaul..... to be continued...
Oh, I found out the alternator had also been previously replaced....although it was a remanufactured one.
