Hi . I have 535d and I need to do these stem seals . Do you only have piston at top and the valves dont drop to far to allow replacement or is there a trick I'm missing ?
NO! Don't use metal tools to pry them up! You will score the shaft! And why use screwdrivers to push back down? Cover the ends of the shafts before you push the seal down and lubricate them! AMATEUR!
This is just a guess but it makes sense to me, in order to keep the valve up, you'd either turn them on your crank shaft with the right size socket and a breaker bar, or, you would turn them electronically with a remote starter switch.
Really good video, thanks!
Thanks a lot dude, very nice job. I've a question for you, can I use this method for diesel 320 e90? Thanks from now!
What tool did you use??

Compressed air in combustion chamber. So the valves don't drop in.

Why important to cover the end of the shafts?
Because the shaft will get an std
Coming back two months later to this banger
What if the valve drops on the piston
So easy, thanks man
May I ask why the valve will not fall down after the oil seal is removed, and what is the support inside
The piston at TDC.
The piston at tdc will prevent it from dropping? That's the only thing stopping me from doing this myself.
I need that spring tool!!
Why remove, oil lose?
How do you keep the valve up?

Piston up
@@tomcat3084 I used on my valve seal replacement small diameter rope and filled the cylinder with it ,I guided it in the spark plug hole .
Where did you get the tool
You can fill the cylinder with air via the spark plug or the glow plug, this will keep the valve in place
No kompressor?
Yes
@@bmwgangrd but how?
Piston up
@@bmwgangrd ok thanks. I thinks IT works on BMW e46 n42 engine
