Rattles in engine compartment, V40 2.0 year 2000

Hello together, sorry if I don’t know the correct technical terms and have to rewrite everything a bit funny, but I don’t really know about engines 😉 I’ve been racing in the engine compartment for a while. I’ve also been able to locate it. It comes from such a pole that if you look at the engine from the top between the engine and the drive room is attached. Looks like a joint rod (I don’t know what it’s called. If, for example, I drive down a small hump and then both do not give a gas and not a dome, it starts to rattle. As soon as I give gas again or a dome it is gone. If I have seen the right thing, the connection with this joint rod, i.e. with the joint, is not right. If I press on it with the screw pull and give gas, the ratchet stops. Is there perhaps a seal or something to fix that? Or does it have to be built in a whole new rod? d i still have a question……at the V40 is the interval for the timing belt lt. workshop at 150,000 KM. As I have seen in the checkbook now this was changed already at KM 83,000 before I bought it. No idea why. Does the change now extend to 230,000 KM????? I would be very grateful for some tips and ideas!!!!!
