Same area as me but the sounds a  few years ago, drips on the same bolts on bell housing ?

Mine was oil cooler plate seal.  Daz sorted it for me   

It seemed to only drip say 15 mins after car had cooler down from warm as never did it initially on park up.  Then dripped a small puddle, not much, hey enough to notice on garage floor, and then stopped dripping as it cooled down.  Guess this was to to with heat expansion and contraction of different materials and coolant pressure ?

Re sealed cooler plate and not missed a beat since.  Worst bit was removing the oil cooler pipes as advice here is NOT TO BEND THEM, REMOVE THEM no matter how tempting.  And replace dowty washers whilst your there.

Hope you get it sorted.

Andy.

Had to reseal a few oil cooler plates on 3.2s now...

So, any news?
Have you found the leak?

[tunnie]

Identified it yesterday, it is the HBV. Although it was dry after a drive, I found that if started it for a short amount if time (30-60 seconds) then switch off and repeat I found it.

Looking in all suspect areas with a torch I found a small drip from the HBV itself, not any of the pipes connecting into it, but the valve itself. Just need to look into ordering a replacement

Bloody crap things!

Phew! That had us going for a while. Glad you have finally found it. You won't be sure until you have changed the valve and driven a few miles without coolant loss. Good luck.
Pity the independent garage that has a customer breeze in asking it to correct a coolant loss, and does all the wrong things first. A guy set up shop in Midsomer Norton 16 years ago, seemed friendly, willing and bright. After 3 years he packed it in, a broken man, complaining that it was 'doing his head in, trying to sort modern cars'. MOTs are profitable, repairs are tough.

In 11 years of Omega ownership, it's my first HBV that's failed, not bad going 

[Diamond Black Geezer]

Well, that's two of us that's done their HBV, then. We'll see how mine goes. touch wood we're both in the clear.

I did one on Friday. They're much easier on a 4 cylinder, as there's no way I'd do a V6 on a hot engine.

[Diamond Black Geezer]

I was down doing the thermostat, so you can picture the state of the engine at that point! The HBV was a piece of cake - but as I say, with the top third of the engine missing. 

[tunnie]

Not looking forward to it, access bloody pain. Hate working on the V6's 

[Diamond Black Geezer]

I'd say that if you've no other reason to strip the engine down (spark plugs, etc) try taking the scuttle off instead of the plenum, far less room for cokcup re: vac leaks, not re-seating the plenum properly etc..

Don't know if I'm the only one to have done this, but I've binned the 24,000 clips that hold the plastic scuttle trim on, mine's held on with the wiper spindles, it doesnt need anything else. Also make whipping the NS panel for pollen filter change very easy and a 10 second job. Just a £1 blob of black sealent to keep the DIS pack nice and dry and you're there.

As said had two dealer HBVs go in 18 months on mine. Just take the scuttle off and there it is. 

[TheBoy]

Its not a bad job with scuttle off, but better molegrips than the ones you have might make it easier.

Part is surprisingly cheap, about £20 IIRC.

The hose clips are tricky to remove. This tool might help.
