Valve seal replacement while in car?? what is needed?

[cstreit]

Just noticed on your pics that your breather tank doesn't run to your carbs, so it's probably not overfilled oil... However a compression test only tells of the leak, doesn't necessarily reveal the location. If you had a bad valve guide, leaking valve seat, bad rings it could show as lower. The leakdown is the real indicator for me...

BTW, was it a hot, or cold leakdown... I'd do both...

I did do leak down and compression just in case some of the people responding didn't know that. He results are in an earlier post.

I ran the fuel out of the carbs and then did the leak down..... Sorry that was for the compression test but the car was warm when we did thw leak down. The spark plugs could be handled for several seconds before you would have to set them down due to heat. They were just hot enough to have to set down. The leak down had pretty good numbers and the compression test was high which is good.

During the leak down if any of the cylinders were leaking bad we would have checked where it was comi from... Just confused as to what could be causing based on my results of test other than seals.. I do have limited knowledge but all the numbers seem good and sometimes it smokes and sometimes it doesn't. Just don't want to tear down the motor if I can avoid it, but this smoking (when it is doing it) is fricken annoying.

What would a cold leak down tell me that a warm one wouldn't?

Smoke from oil overfill is not your problem. You need an airbox and a direct connection between the oil tank breather and the airbox. That's how a stock 911 with an overfilled oil tank smokes. You don't have the oil system setup for that.

How far and how hard did you drive the car to try to clear the oil?
Does the exhaust have an oily residue?
Have you pulled and read the plugs after a good hard run? Results?
