Okay this is starting to annoy me now. The passenger side manifold was easy and I was wondering what the fuss was about but now I am running out of options on the drivers side.

The manifold is unbolted, lambda is out, water rail is off. But I am about 2cm clearance short of being able to lift out the manifold. I can't get enough lift on the engine because the engine mount hits the steering shaft, and the engine mount plate won't come off unless I also remove the oil? pipe bolted to the front of it.

So do I take the steering shaft off or do I have to remove the oil pipe (and drain the oil etc etc ) to give enough clearance to get the engine mount plate free. In any case is there anything else I need to remove ??

I am going to have a beer whilst I consider this but any advice would be welcome.

I think you have to remove the engine mounts and once the passenger side is out try and push/jack the engine and gearbox over to create space.

Here is a thread which may help:

As far as I can remember, you have to slacken off the engine mount plate, and then lever the engine across to the passenger side, and then you can extricate the manifold with your other arm. A helper is invaluable. Refitting is the reverse of removal, and significantly more tricky.

Thanks both of you that sounds like a good tactic, and I am now much more relaxed than earlier this evening. I love the old Haynes saying refitting-is-the-reverse-of-removal.

If the manifold is knackered much quicker to use an angle grinder. Saved me loads of time and stress.

On the other hand, if you are reusing it......best follow the advice above.

Woo hoo - thanks for the advice.




The last two pieces of the jigsaw where to remove the oil filter (to allow more movement of the engine) and the master cylinder cover. I can't think of the last job on any car which required so many extraneous pieces to be removed just to get a couple of components out.

Now to weld up a crack in the passenger side manifold, get both of them coated, replace the engine bay heat shields and paint up the chassis rails whilst they are accessible.

Wish my garage floor was this clean. cool

Is it worth welding the manifold and coating it when they are prone to cracking? Mine were cracked in several places and had been repaired several times before. So decided on a stainless pair from ACT which are supposed to not crack. Time will tell I suppose.

That's not the garage floor.

There is only one crack on one manifold and no sign of previous repairs so I suspect it wont crack again for a while if it is welded up cleanly.

Well done for persevering. I know only too well how tricky these cars can be sometimes. The simplest of jobs can take hours more than expected and can be really frustrating.

Why did they not make the air-boxes (4.2) with a quick release method - like the air filter top - instead of those time consuming screws? It would have been soooo helpful.

The manifolds have now come back from Zircotec after being coated.


And whilst I was there I had the water rails, cam covers and passenger side water pipes coated with Zircotec's 'matching surface coating', i.e. same appearance as the manifolds.

Is that the Zircotec 'Primary Black' coating for budget concious owners like me?

If so do you have a price for the manifolds alone, and then for the extra items?

Yes that is primary black. Its not very 'budget', I paid £550 (incl VAT) and that was at a significant discount due to an initial mis-quotation. It does look very nice though and the matching surface coating looks very good on the cam covers. I was very tempted to have them in a colour but that put the price up rather too much. I'll post more pictures when it is all bolted on, unfortunately its being edged out by a kitchen refit at the moment.

If anyone needs some 4.5 manifolds to send off for coating or otherwise let me know, I have a set without any cracks available.

Jeez - does that mean the standard coating is IRO £800 for a pair?
