I recently purchased a 99 ES300 from a friend who ran into hard financial times. The car needed some work which I had performed. Among the problems was a misfire in cylinder #2. I replaced the spark plugs and coil pack for the whole motor. The car runs great now BUT, it smokes blue at start up for about 40 seconds after sitting for any long period of time. Lots of smoke. It didn't smoke before I did the work. My mechanic says (and I agree) that the problem is the valve stem seals on cylinder 2. My question to everyone here is this. Can he compress the cylinder to perform the seal replacement? If this can be done, he won't have to remove the cylinder head. That would save me a ton of money. If this isn't enough info, let me know and I'll try to clarify more...Thanks for any help you all can give.
