Loose Rocker Arm, is this a big job now?

Are you moving the cam to the right place before checking the clearance?
When the cam is opposite the rocker that's when you check the clearance.

If they're loose then tighten them to spec.
Is it the exhaust ones that are tight?
 
Yeah so that video is of the C1 exhaust when it's in the correct position (I have a Haynes), the intake moves slightly on C1 too but then I can do C2 exhaust and C3 intake and they're solid. Then when it's at the next cam stage I can do both C4 and the opposite of C2 and C3 but then the C1 cylinder moves about loads. Looking at videos online peoples look solid.

Guessing maybe part #11 is broken on some arms, I don't think the clearance has been done as I couldn't get 0.05mm in any bar the ones that flap about :(

Intake should be .10 to .15 and exhaust is .18 to .23 :eek:
 
wouldn't it be worn/weak valve springs if you have excessive movement?

might be worth changing them anyway
 
You know I keep looking at the vid & it almost looks like the cam lobe is in the wrong position, I really wish you hadn't blocked it with your fingers.
 
Wouldn't be valve springs, even if they were weak they'd still close the valve fully.

Spring 11 on the diagram looks like it should hold the rocker arm on/off (prob on) the valve, if this was broken it would cause the arm to move freely like in your vid. It won't be a strong spring.

Either way it wouldn't change you clearance so that still needs adjusting.
The tight ones need freeing up too, these will be holding the valve open slightly allowing exhaust gases to pass on the compression stroke, that will slowly burn the valve or seat away.
 
ye looks to me that either 1 your not TDC or 2 they are way to slack. i have seen rockers seize but not go sloppy loose. unless timing is out.

Spring 11 is simply used to space out the rockers on the shaft, there is one of these between every rocker. This spring being broken or weak would not affect the valve clearance in anyway.

It looks to me as though the valve clearance is simply miles out of adjustment, which does suggest you might want to check for possible cam lobe and rocker pad wear.

The valve clearances don't get any looser with the piston at a different part of the stroke :D You measure them at the slackest point, which should be TDC on compression.
