Engine moving valve springs

i am making engine model for my university graduation and what i basicly need is to fil valve with those handlers and springs in picture 1 into valve into picture 2, where its all engine assambley, i can move valve with springs alone and its fine, but i cant find a way to get those springs moving into engine assambley, already spent like 10hours trying.. when i use drive (rotate camshaft for example) it just wont move bcoz it doesnt understand spring is actualy pushable.

Right click on Sub Assy and then from the drop down menu click FLEXIBLY

You need to create an adaptive spring.
Have you made the spring with design accelerator or with the coil command?

i made it as adaptive with coil command, and when i just push it , it works great i mean with constaint like 30mm to 50mm (in second picture where there is valve only, there it works). problem is, that when i put that spring into assambley, first i cant really connect it to those 2 rings who holds it, bcoz there is always some error and secondly than i cant rotate the engine.

You need to make every sub assembly Flexible. To do that go to the history tree, right click the sub assembly and select flexible from the menu.
Then when you drive the constraint that animates the engine you should check the drive adaptivity box.
I hope this works

i have it all from parts really (the engine),i just tried to insert that other assambley with valve and springs and i can make it adaptive (what i did before aswell, but it still didnt work) but not flexible, or maybe i just cant find the option there.. and i should try to make all those constrains adaptive aswell i guess, as i have like 4 tang from each valve till camshaft, altho dont think they will let me to make them all adaptive.

i made sub assamb, both springs where adaptive in it, and when i finished it, i made it flexible, still got error when tried to connect it to rocket arm :( maybe i can just send that engine to u, and explain via skype or something what is what there (part names are not english) etc, so u could take a look, as its my final job for university i would like to get working springs there instead of any :(
