valve guide oil seals

got this VK 3.3 have stripped the head down, I noticed the valve stem oil seals are fitted below the washer, right above the guide but when looking at the gregorys manual it shows the seal fitted above the washer. I think the way the seals were fitted would allow them to be squashed or pushed out of their grooves when the valves are operated, whereas when fitted the way the gregorys shows they would not.
what is the general feeling on this?
Don't want to have it pumping out oil when driving!

thanks

The Gregorys Is Correct.

Someone has confused the later type Umbrella Seals.

The Umbrella Seals are abrasive (they stay still and rub against the Valve Stem) with grey/red/black motor Seals which travel with the Valve ...

Holdenpaedia, they're the brakes Mate.

your valves should have 2 grooves, top groove for the collets, second for the seal. when the spring is compressed, fit the seal, work into the groove and when you release the spring with collets in place it should make an oil tight seal around the inside diameter of the retainer, stopping oil flowing down the stem of the valve.

i have seen some people just put the o-ring seal anywhere on the stem so it seals off the guide only at max lift - guess what, they smoke this way.

if you have aftermarket valves with no 2nd groove, silicone in place of a seal in the groove will work.
