Thanks TJ450. Just tell me this - from what I can recall, you have refitted the inlet manifold a second time. Do you still have all that piping in place. If you do, tell me how easy (!) or difficult it was to line everything up. Regards Styria

All the piping is indeed still in place. Getting everything to line up would have been good, but it never did line up in the first place, as the pipe was touching the spacer tubes between the manifold halves already and even then there was still an extra few millimetres required to clear the LH cylinder head.

I resorted to belting the pipe with a hammer to flatten it out slightly (cringing while doing so) in the interfering areas, but even then it still clipped the edge of the gaskets (not causing damage, although it did the previous time, hence the leak).

In the end, I actually removed both gaskets. I then lowered the manifold in and moved the unit back towards the firewall and worked it in, manipulating the position of the pipe and it finally let go. I then had an assistant (my Brother) slide the gaskets in from the front on either side and into position.

After that, I installed the new bolts from Coventry's Fasteners and torqued them down in steps to 25nm and used non-metallic anti-seize compound. It was then just a matter of tightening the nut on the pipe-to-plenum fitting and fitting the throttle housing.

I guess I'll find out in due course as to the effectiveness of that ordeal, nut I'm pretty confident that it will be OK.

Hi TJ450, that, indeed, is a great effort - I dips my hat to you. Even removing those little puppies is hard enough. Putting them back - yuk. Regards Styria

Just an update with a few pics to illustrate and demonstrate any number of things, but primarily cleanliness and all the paraphernalia that needs to be refitted.








These pics were taken some little while ago. I am pleased to convey that I have struck no 'after-assembly' problems and the engine is running quite sweetly with much better pick up from low than before all this work was done.

As is my wont, I thoroughly cleaned out the small sump and the oil reservoir several times with high pressure kerosene and, of course, prior to that, I was able to thoroughly wash out the water jackets in the block as I had removed the housing that's located between the water pump and engine block.

Paintwork turned out excellent. I am pleased to convey that no 'slicing' nor buffing has been required and orange peel has been kept to a bare minimum. Pics to follow in due course. Presently coming to grips (fixing) the central locking system. Regards Styria

Styria this would have to be one of the best articles I've seen on TK!

Kudos to You and Mercules both.

regards,
Tony

Hi Tony, thank you very much for that. Yes, I do think it is great 'library' material - probably better than perhaps even a MB workshop manual. Don't forget Tony, that there is an additional thread dealing with 6.9 headwork under the heading of "further grinding and de-coking" that I carried out on the Astral Silver 6.9 that was bought by ChrisP.

When I think back today, there are two items that I would remove prior to attempting removal of the right hand head - remove both the power brake unit, as well as the steering box. With those two items in situ, the removal and refitting are an absolute nightmare. Obviously, with the brake booster removed, it also affords the opportunity to replace the sway bar bush - a much neglected item. Regards Styria

I have new front and rear sway bar bushes on the way for this xmas' orgy of repair and thought the same thing the last time I had the booster out.

Wish I'd had the new bushes then.

If any of mine get to this point I'll seriously consider pulling the engine out.... BTW well done Styria for such a comprehensive series of pics and dialogue!

Hi Mark, that's what it is all about. When you are proud of what you're achieving, it is satisfying to share it with others. If someone can learn something from someone else's experience (such as it is) and even trials and tribulations, it's all worthwhile. Regards Styria

I have re-visited this thread which involved removal of heads, valve grind and de-coke of my Gleaming Beauty (6.9). I came across the thread accidentally when commenting on another post, and I discovered, much to my surprise, that the restrictions by Photobucket appear to have been reversed. Well, of sorts. The pics are there, but bear reference to Photobucket.

That to all intents I am not particularly worried about. Many, many times, I considered digging out the photos and re-submitting them to the thread itself. That will now not be necessary. Couple of observations. This work on Gleaming Beauty was carried out in 2011 - eight years ago. I really don't know where the time has gone, and obviously I have not used Gleaming Beauty all that much. What I can convey is this - since the advent of that work and up to now, at no time did I experience any water leaks, oil leaks nor any fuel leaks. Nothing further has been touched - cold start, hot start, spark, .....nothing. I walk to the car every time, simply turn the key and it starts. I think I have good reason to be pleased with my work in re-assembly and the very able assistance rendered by Mercules at the time. Regards Styria

Iím glad this post was brought back Styria.
I may not have seen this at all.
Thank you.

A great read and a great result all those years ago.
