350i manifold broken sealing doughnut
Discussion
Hi All,
So managed to manhandle the driver's side manifold from its resting place, to allow me to replace with the second user one supplied with the car.
However, the doughnut sealing ring has fallen into 4 pieces.
Would anyone have one knocking about that they would like to pass over, so as I can finish the installation?
On top of the many other jobs, there was dripping water when jacked up, so looks like the water pump has sprung a leak as well...oh well the joys grin motoring.

You can get olives from exhaust fitting places, they aren't expensive, take the old one along.
In case you need to buy a much wider one, then buy two so both sides are equally offset, the exhaust will sit 10-20mm further back no problems, but you might also need to use longer bolts in the clamps.

Hi Adam,
Once again thanks for the reply. My experience of local exhaust fitting people around here (particularly known nationals), from the past is poor. If it's not a BMW, Mercedes or a car that is not less than 10 years old, then they just say sorry. I had a similar problem recently with Scimitar GTE rubber hangers.
Most modern joints that I have seen on cars are very different now from a clamping perspective.
I will give it a bash though if I can get out.
Cheers

Old thread but suggests it might be a Jaguar part. (At least for a 390, don't know if they have larger exhausts.)

Hi Grady,
Great thanks, had read a few threads related to this, but funnily not that one.
I have found some at ACT and Racetech, I find it very hard to get my head around the postage being more than the actual part, what starts off looking a reasonable price at £6.25 or £6.80 ends up being a fair bit.
Got a few feelers out on flea bay, my description was a little off it appears to be called a sealing olive
Back before August earning shed loads would have not been an Issue at all, current circumstances now though is a whole new ball game
Hard enough just trying to hang onto the Wedge.
I had a similar Issue some time ago, ended up having one made, luckily at the time the place I worked at had a tool-making department.

Someone else had the same problem back in Feb18 and I found my response to that here:

I don't know whether they took my advice or not but Ebay item 230683030206 is what I used with a touch of exhaust sealant. Many years later they're still nicely sealed. The originals did look like the Jag ones so I'd recommend buying a pair of these ebay ones. Good luck, Steve.

Hi SLB,
Many thanks, I did read that post, however, I was hoping to replace only the one at this point. This due to restrictions (space around the car) in the garage. Although I may have to bite the bullet and do the pair.
The listing shows dims the inner and outer Dia should be OK, however, the thickness is about half of my broken one.
The broken one measures:
Outer Dia 61mm
Inner Dia 48mm
Thickness/Height 19mm
I will keep your recommendation in the back pocket, at the moment.

I have had these on the car for 12 years, BLG10's

but they are "deeper" so you need longer bolts and the exhaust sits a little further back.

Hi Adam,
Quick question. Unfortunately, the link you gave was for one only. As per usual, previously used parts tend to fade away over time, and become hard to find.
I used this link, to glean alternatives.
https://www.eazsrz.com/index.php?main_page=product...
It stated various other part Nos so I went for NTC 1030 as an alternative, however they are much larger than I expected. Can you from memory (I know this was a while back) remember if the taper of the olive fitted well into the flanges of the mating halves, as the ones I have purchased just about engage. Not really enough I feel to seal properly.
A rethink may be required, these are destined for the nearly there bin of spare parts for many vehicles I reckon

As I recall the taper engages near the end of the olive. You wouldn't want it to be mostly in because that would imply much smaller diameter openings in the olive which would impede gas flow.
My recollection is more recent because I remove and refit them regularly if I have to work on the exhaust.

Having had a little engagement with a speed hump in the 390SE last year I had to remove and reseal the exhaust. The olives definitely were very much "out" of the taper. Mine also has the thicker steel olives. I did reassemble with a good smear of exhaust paste on all the surfaces. It's been fine since, although TBH the SEAC is now the daily driver and the 390 isn't used much at all.
