Just curious...
Why would this make you nervous?
What makes me nervous is that setting the valve lash means that the engine has to be rotated several times by hand in order to put the lifters at the right location to check the valve clearance.
A gasoline engine requires a spark to start, so rotating the engine by hand is safe as long as the ignition is turned off. I've set lots of those without a worry.
But a diesel is a compression ignition engine with a mechanical fuel pump and as far as I know the M59 doesn't have any form of compression release. Those things all combine to add up to a chance (small chance, but real) that it will fire when rotating a piston through the compression stroke. There's just no easy way to make most diesels absolutely safe to rotate through the compression stroke.That's what makes me nervous about setting the valve lash on the M59 without removing either the injectors or the glow plugs....and I hate to remove either unless I just have to.
luck,
