Thanks, deanyel. I was told by seller, 2nd owners, they thought engine was changed. I ran my VIN at the link you provided. It definitely is not original engine. I also have the engine out and the block stamping in clear view. The full engine number is 104 981 12 001 061. Four digits follow, the first, is an upside down, backwards "3"(yes, i am sober, standing straight up), followed by 10.0,[(3)10.0]. I would like to find out exactly what this engine is, and also, this clarifies some part identification questions I have encountered. I am also back to my original questions as to what steps should I take to correct everything.
