I think the more usual way of doing this would be with the head gasket face horizontal, and the fluid poured into the combustion chamber.
If the valves have springs attached, then this suggests something is odd.
Did the machine shop check the valve seat runout, using something like this:-
That's P2B93 and P25B4.
Difficult to say which one is first - a bit chicken and egg - but to me if the position sensor on the turbo isn't working properly, the ECU may not be able to tell whether the turbo actuator is stuck or not.
Regardless of whether it's a wastegate or a Variable Nozzle...
Would be helpful to know which kinds/makes of vehicles you're looking at diagnosing.
There are hundreds of options out there, from generic to marque-specific.
Not sure if you've already tried, but bleed at the master as well if you've got the access. I'm guessing the master outlet is the highest point in the system so air will be trapped.
Had the same on a motorcycle hydraulic clutch system which was the same. Finish off with a bleed of the master and...
I mean does the pedal come back up far enough to allow the piston in the master cylinder to come all the way back out to it's stop? Usually that would mean a small amount of free play in the linkage before the pushrod starts moving the system.
I am aligned with you that extending the pushrod...
@steveo3002 is there any freeplay at the clutch pedal end? Could the pedal or push rod be stopping the piston in the cylinder coming all the way back out? This would stop the air coming back out of the master cylinder because the fluid feed port (from the reservoir) would be partially closed.
Means a bigger master cylinder will push more fluid out for the same pedal movement. So yes, an extra 2mm diameter would affect it - you'd get a heavier pedal.
This isn't an application with a clutch delay valve, is it? **EDIT - '91 G60 so guessing not.
As you've replaced the slave, which on...
M/C having a nipple is a good thing, as you can get the air out of the end of the master (sometimes the highest point on the system if the bulkhead/cylinder is leant back. Try a manual bleed from the master, then go back to the slave.
If you know the size of the wheel bearings in your current wheel, could they be swapped for ones with a larger ID but the same OD and width, allowing you to use a bigger diameter wheel spindle? How big do you think you'd need to go?
Where does the other end of the Br (brown?) wire go? Looks like a resistor and a capacitor, which would be some kind of smoothing pulse/voltage circuit? Does it run a rev counter?
www.cmsnl.com also hold spares for the older Hondas, but don't have the G50 listed. If you can find a parts manual (eBay, etc), you can search for the part number directly on their site. Have used them before, postage is expensive but sometimes it's a case of "where else am I going to find these...
Are they A50 wheels? A bit of Google image sleuthing suggests they look similar, and were 15" before 1956.

Nice work on the tool. I made a similar one to do the valve guides on a motorcycle head - same number of valves you have there. I didn't harden it at all, and other than some "mushrooming" of the end that gets hit with a hammer, I didn't see any other problems.
I think the commercially available...
Maybe a picture of the bearing or installation would help the knowledgable folks here to impart their wisdom.
What type or bearings are we talking about here? Ball, roller, taper, plain bush, etc?
Had a weird fault on a Rover 25 like this once, ran fine but under hard acceleration the engine would start to kanaroo, as you mention.
Turned out the connector to the throttle position sensor was dodgy, and when the engine rocked under load the connection broke, then when it tried to die the...
I have one like that from Machine DRO (I bought the 18-35mm version) and for the price and the amount I needed to use it, it's been great. Seems smooth and pretty repeatable from what I can see.
I also got a very small one from Dasqua/Chronos, and can't fault it either...
