No there are some extremely knowledgeable folks on this forum. Am hoping that once the seals are changed the rare hesitation I have will go. Then at some stage to look into the clunk I sometimes get from the rear end when I change gears without compensating sufficiently well with the accelerator - another issue that seems quite common....it never ends!
By the way that clunk from the rear end driveline will more than likely be the prop-shaft splines into the diff requiring some grease Drop the exhaust, drop the prop-shaft, apply correct grease...sorted. Another job you can tick off the list

Brilliant - you have answered my next question re which grease to use as well!ay well get this done at the same time...and perhaps get the CDV removed as well!patriot66 wrote: ↑Sat Feb 18, 2023 6:20 pmNot too long.

Thinking about it patriot66, is it much extra work to replace the donut at the same time as greasing the prop-shaft? For all I know it could be a totally different job altogether but thought I’d ask! Cheers.

Donut is t'other end of the prop-shaft, immediately on the back of the gearbox. Not a massive job to replace that also but the centre bearing/u.j joint support would need undoing and lowering also. My donut was like brand new so left it well alone. Unlike the splines at the diff end and centre bearing which as you can see were bone drypoortomsacold wrote: ↑Sat Feb 18, 2023 7:33 pm Thinking about it patriot66, is it much extra work to replace the donut at the same time as greasing the prop-shaft?

Those pictures are really helpful, thanks very much. I’ve ordered the grease (cheap as chips as it is) and will get my mechanic to give that a go, and will ask him to check the donut if he can whilst at it.patriot66 wrote: ↑Sat Feb 18, 2023 8:56 pmDonut is t'other end of the prop-shaft, immediately on the back of the gearbox.

Just to keep you all updated in the hope this may help others, but today the mechanic has reported that the noise is the water pump being on its way out. I cannot remember if I said but the rattle came on quickly and got progressively worse over the space of a week. So mechanic feels confident it's the water pump, so will be replacing that and checking/replacing the belts and possibly thermostat at the same time.
And whilst it's in he is also replacing the gearbox and diff oil, greasing the rear diff and, if he can, loosening the bloody bolt that is stuck under the steering column that is preventing me from performing the steering fix!
We will get there....one day!!!

Right car is back, water pump replaced and engine rattle has gone. Really had no idea that a failing water pump would make such a worrying noise, so hopefully this post will help reassure others who have the same noises coming from their engine bay - not an expensive fix, plus got the belts done at the same time which is a positive as was told they were very worn.
Plus he managed to get the bloody stuck bolt moving again!

Suggest you have nothing further to do with them.
Glad you got that sorted, and one to store away in the memory banks.

Well to be fair I had my ear against the vanos area of the engine and would have put good money on the noise coming from that area of the engine. Just goes to show how sound must travel.enuff_zed wrote: ↑Wed Mar 01, 2023 8:12 pmNo idea what idiot suggested it might be the vanos.poortomsacold wrote: ↑Wed Mar 01, 2023 8:06 pm Right car is back, water pump replaced and engine rattle has gone.

Glad the rattle has gone What about that hesitation/surging in 2nd and 3rd at low speed ? Is it still doing it ? Are you getting the VANOS rebuilt ?

Not driven it for long enough to find out yet. It only ever happened very occasionally - maybe only once or twice a week at most. But having read up on vanos rebuilds when I was certain that was the problem, I think I’ll look to have that done in due course anyway as it sounds as though it makes a noticeable difference.

One does not simply remove the exhaust! I've been soaking my exhaust flange nuts, (which are odd in sizes) to no avail. They will not budge. 13mm socket sidewall blew out.

That depends whether you've already tackled the issue of well corroded flange studs and nuts previously or notMaddo6659 wrote: ↑Wed Mar 15, 2023 3:32 pmOne does not simply remove the exhaust!
