hey Matt, The following is from a thread response (from lightman) in the diesel discussion where it was a 99 turbo having plugs replaced. These are probably a good indicator.
Go figure as I'm driving today neither the glow plug light or CEL is on. I suppose I'll be ready when they re appear.

" "9. Install the new glowplugs.You may also want to dab a little anti-seize on the threads. Thread them in and torque to 27NM. Install the glowplug caps, they will push on with an audible CLICK.

10. Remove old intake manifold gasket and clean head's surface. Remove all rags from the head.

11. Align and lay out new intake manifold gasket. Don't worry about it staying totally in place at this point.

12. Reinstall intake manifold onto intercooler tube, and be sure the egr assembly is 'plugged in' to the corrugated pipe. Install the clamp to hold them together, however just tighten enough to get the bolt threaded at this point. Be sure the egr is firmly seated on the intercooler pipe, and the manifold is seated flat on the head. Might take a little push to get it down flat.

13. Using a flashlight, look down the holes on the top of the intake manifold. If the gasket is lined up, install the bolts. If not, lift up very slightly on the manifold, and using a thin/long screwdriver, scoot the gasket until the holes line up. I suggest doing this at one and and then the other. Once you've done that, it's pretty well lined up. Be sure it's totally lined up with one more center bolt, and then reinstall all the manifold bolts. Thread them until they are all snug, not too tight. Then working from the center out, in a top bottom top bottom order, torque these bolts to 20NM, or 14 ft lbs. " "

Thanks again.Looks like I'll be doing this later than I expected. Now that I've bought the glow plugs & relay switch, anti seize,deep sockets,& a gasket on order I'm an accident waiting to happen !
