Hi,

yes you need compressed air to keep vavles up. If you let them rest on pistion crown you risk that they will be bent.

Hi Styles,

white smoke may come from a bad cylinderhead-gasket. Blue smoke e.g. after ideling at a traffic-light would more fit to worn seals.
You worry about dropping the valves – but that won’t be a problem. But to release the keepers after decades could be a patience proofing job. Just check youtube for inspiration:

As Volker wrote – don’t place the piston in TDC during trying to release the keepers! You can buy a good toolingset at ebay that will help you to handle the springs and take off the old seals. Don’t try this without the special gripper! This guy here is using this set and tried all ways - find out what ist the best for you.

Hi Martin,

that 2nd video is of a very rough nature. Inserting rope to block the valves form falling down and then hammering on the spring keepers. At least last technique I would not really try on my cars.
