				Any body ever measured hydraulic tappet clearance on a M102/M103?
			 
			 
			
		
		
		
			
			G'day Folks, 
 
A few people have (rather rudely) asked me if my W201 is a diesel! 
 
I know that that's possible but it has a nice little M102 in there. 
 
I've had a look at the engine and all seems as I remember it before I took it to bits... 
 
...oh dear(!)... 
 
...but I can not help but to wonder if I have the correct height ball socket feet fitted between the hydraulic element and the valve stem. To check this (and the operation / clearance of the hydraulic elements) there's a procedure in chapter 05-214 (in the FSM). 
 
It all looks kind of gucci with a special tool that fits onto the rocker arm => 
 
102589042100 - only 10 left in the world and costs about 230 euros from the dealer (cheapest price I can find) 
 
I think the special tool essentially is a clamp that is used to compress the top of the hydraulic element. 
 
I was wondering if anyone here has seen or used this special tool. 
 
I was also wondering how loose the rocker arms feel on a M102 / M103 engine with the hydraulic follower touching the lowest part of the cam lobe.
