W124 E300D Inlet Manifold

[SlowlyButSurely]

I need to change the glowplugs on my 1994 E300D Estate. It's the six cylinder non-turbo engine.

I can't for the life of me work out how to remove the inlet manifold. I've removed all the obvious bolts but it's still firmly attached. Can anyone help?

Thanks.

There is a support frame under the manifold held in with three bolts, two on the manifold and one by the engine mounting

If you look on the gaskit 20,you can see all of the fixing holes,if they are all out is it just stuck ? tap with a mallet ?.

Think I have put up the correct version pic.

Before you try to remove the glow plugs have a read of the numerous comments on this forum about the job

Thanks for the replies guys.

It's the bit that goes across the rocker cover that I can't get off. Looking at the diagram, it appears that I have removed all the bolts. Just need to hit it harder I suppose. How hard should I need to hit it? I was a bit cautious because it doesn't look very strong.

I've seen all the other posts about this job thanks. I once had a glowplug snap off when trying to remove it (not on a merc though). Not funny. Had to remove the head and drill it out.

Incidentally, does anyone know where I can get a proper workshop manual. I find The Haynes manual is not very useful.

You'll find this place is better than any workshop manual you could find And its free!

With reference to the picture posted by Malcolm, part number 77 is held on by 4 bolts ( 10mm on mine), remove these and then remove the (un shown ) exhaust coupling from item 77. This too, is a 10mm bolt, and connects item 77 to the exhaust manifold via a flexible tube.
This will allow you to pull item 77, from the the end of the intake manifold that goes over the rocker cover. The rubber O rings on either end of this part are a tight fit, however, you should be able to lever the item out, without resorting to a hammer.

Hope this helps,

I'm going to be doing my glowplugs soon, so please let me know how you get on

Andy,

I think that must be the step I was missing. I will have another go at the weekend and report back next week.
