I hope Pyro doesn`t get mad because i post here .
I want to know if it`s possible to change the rubber valve seals on my b200e without taking the head off. Can i insert something thru the spark plugs bores in order to keep the valves from falling down?
Thanks.

Well its not very helpful for searching to mix topics like this, but anyway you can in theory push rope into the cylinder to support the valve and then compress the spring from above. You may need to fabricate a spring compressor.

Sounds like you are worried about removing the head, its pretty straight forward and you get to grind the valves in.

Sorry for mixing the topics and thank you for your answer.
In deed, i do not want to take the head off- i`ll have to wait for the head gasket i don`t know, 2-3 weeks, borrow the torque wrench and so on.
