I was most likely going to order BMW seals, but it's not like BMW has a good track record with its o-rings and seals actually sealing. I've done nothing but chase leaks since I bought it! I guess 140k miles is a bit, but I've had Honda, Toyota, and Nissan cars that have gone over 200k with nearly no leaks ever! You'd be extremely lucky if you owned a BMW Went 100k without springing leaks... rant over!
Unfortunately you cant compare Japanese to the German engines. The Japanese engines are sealed with seam sealer instead of gaskets. It is really good. I am convinced that the Germans allow for leaks to develop so that there is built in service or the customer thinks the engine is coming to an end and then rid/replace vehicle. Its a very effective scare tactic on the German designers behalf.
