I agree. Then we can all get on with the really exciting part - the debate about how Simon should have done the job!

I have never been near a KV6 but already have my critique all prepared.

Interesting discoveries. Shame we can't really see the thermostat housing.

I also found that some bolts were tighter than others when removing the inlet manifolds last week (not my work), but I also remember a post by perhaps Lovel where he mentioned the need to check the bolts a week or two after reassembly.

Any evidence of water permeating the inlet gaskets?

Keep well

That would be nice Dave.

The latest is that gloopy black mastic had been applied, presumably by the garage in France, to parts of the inlet manifold gaskets and to all the 'O' rings. The curved pipe was stuck fast and it took me an hour to get it off but I managed not to damage it.

I now know that no attempt had been made to tighten both the serrated clips. Only the 'O' ring at the base of the thermostat housing had flattened. Those on the straight and curved pipes were in good condition. I'll renew them all of course.

Now where have I come across that before Maninder?

Let me know what you're interested in Mike and I'll see what I can do.

Wow, you'd have to be dedicated to do that! On my own car I tightened them to the specified torque and have never had any problems.

No. The LH was rippled at the top and had elastomer failure above no. 5 port but the coolant channels were protected. The RH gasket cleanly broke in two as I withdrew the manifold. Fiona has reported that the temperature gauge hit the twelve o'clock position on at least one occasion.

Tomorrow's jobs will be to clean the manifold faces, remove the black sealant from the coolant pipes and order new parts!

To everyone who posted today, thanks for your professional interest.

Simon

I thought you might like to see what I've been dealing with today; the black gunge!

Glad I do not have to use that garage. What a mess. Even an apprentice would not do anything like that withthe Black gunge. I along with many of us have no doubt seen other bodges on vehicles, done in the belief it may work. Hope they did not pay for that abomination of a ‘repair’ . I wish you all the best with this repair Simon.

Default Plenum chamber puzzle

Has anyone else got this, a rubber seam strip floating below the seam with extremely messy rubberised adhesive stuck to the panel above it:



Simon

Edit the following day:
I've discovered today that the loose rubber seam strip pictured should be attached to the rear of the splash shield and not crudely stuck to the bulkhead with black rubberised sealing compound.

Those garage MECHANICS had NO IDEA if it was one of them.-------Looks like an unnecessary attempt at a water seal.--

Not a factory fitment that's become displaced then Jon?
