Anon-E-Mouse,

I have done this a number of times, and have used a variety of means to rotate the engine. My driveway has a slight slope, so I park with the car facing downhill and put it in 4th gear. Then, when I need to move the engine, I pull it toward me while standing in front. I have also used the power steering pulley, but I have never gone through the trouble to remove the glow plugs unless I was changing them. Not a hard job, just cuts your hands up a little and takes time. If I can avoid taking something that works apart, well, the old "if it ain't broke, don't fix it" saying comes to mind. I have heard there is a chance the power steering pulley bearing can be damaged if you apply any forces that generate side loads or bending moments.

At any rate, you do not have to be worried about the exact position of the cams, the lobes just have to be pointing mostly away from the rocker arms. You have to pay attention to which valve is an exhaust and which is an intake, as the position changes from cylinder to cylinder. Look at the intake and exhaust manifolds to keep things straight. I do one cylinder at a time following the firing order on the valve cover. I know you can do more, but then you have to keep track of them.....

I have rarely used the wrench to hold the spring retaining part, and when I do, I find a postion where it is on and wedged in place so the direction I am turning the valve lash adjustment acorn nut and lock nut will not rotate the valve or spring.

I also usually rotate the engine a few more times and check things to make sure I was not too rushed, and that the gap stays stable.

Good luck, Jim
