So my car has 58k original miles, so it was not super dirty, I did take the engine out to do a valve job and replaced all Gaskets and seals as well as the freeze plugs on the block, I used simple green to remove old oil build up ( front main seal was leaking), once I got everything nice and clean I used Meguiars Hyper dressing to give it a bit of shine. the Carbs were cleaned and rebuilt by DeQ, I just keep them clean and shiny. As for the breather yes I’m running something I installed under the car, and maybe it’s my imagination but it seemed to help the engine fumes I sometimes smelled while driving. I did find a receipt for a new cylinder head installed by the BMW dealer, so I’m guessing that is when the sticker was installed on the valve cover, the block is original. These phots were take the day I purchased my coupe, November 2009, I found the car I a garage in Los Altos California were it sat un driven since 1993. Thanks for the nice comments
