Blue smoke on deceleration When I first start the engine, I get a lot of blue smoke for the first couple minutes, then it's fine until I put back pressure on the engine - ie when downshifting on a hill so I don't have to ride the brakes - then upshift, it blows blue smoke for 30 seconds or so. The o-rings were replaced about 1000 miles ago. And I could swear there were receipts for the valve guides as well, but don't have my hands on the docs right now. The car has 220k on it.

Blue smoke on decel is due to valve guide wear, you will need the head pulled and the valve guides replaced.
