A bit of practice and you can flick the adjuster, you can soon see which way it goes.

Omega General Help / Re: Coolant leak
« on: 11 September 2019, 19:26:17 »
Starting to think again it's expansion tank, I checked tonight, found moisture around the rim of the cap at the bottom.
Top of the tank is showing signs of the dye.... (before this tank was clear all over, with nice red GM coolant) the dye has affected the colour.
Again, bubbling sounds around cap, if my ear is close.

« on: 11 September 2019, 13:51:10 »Despite what GM shove on the sticker, its not really good for 5 years. In the same way my XJ shouldn't have to wait 16k for an oil change. I generally like to change my 5yr coolants at 2-3yrs, and the older 2yr coolant annually (though the Kawasaki was the last vehicle to use that)
Coolant, like oil, starts to degrade from the second it goes in, and I know you're not daft enough to leave your oil in for 20k, as per GM spec. No offence intended with my earlier remark, but we know from previous posts that the Omega has been at the bottom of the priority pile. Just offering as a suggestion as to why the normally bombproof 3.2 MLS gasket has failed, *IF* it has. I'm not yet convinced it has, as a coolant to cylinder failure would often give massive pressure in coolant, and exhaust fumes in coolant bottle. Personally, I'd be getting my ass in the valley, and pressure the coolant to around 8psi.
As said, not offence intended in any way, and hopefully none has been taken.
There is no sign of high pressure, everything runs great apart from the drop. The starting issue is now clear, if I leave ignition on for ~5seconds before starting. It now starts smooth, with no issues. Given the amount it lost on Monday (half the header tank) I would have expected it to run poorly, but it was smooth as silk all day and was never down on power.
My next job is to get the Plenum off, I would hope the amount of food colour dye I put in would show if coolant bridge/oil cooler plate was at fault.

But then again I of course neglected my 2.2 with poor serving according to you.

And? It’s 5 year stuff.
GM state:
5 years or 150,000 miles
Nabbed from GM: *5 Years Longlife Protection. -36°c (Ambient) Winter Protection.
Like anyone here has not gone over the 4 year belt rule, or bent anything else as per rule book. But thanks as always for your condescending approach to me.
Let's also forget I took my 2.2 past 190k on it's original HG, yet many others failed way before this, despite being looked after.

Given fact I've spent a lot on welding, annual services, inspections on all belts/fluids/plugs, annual oil changes, brake discs and pads last year, I reject poor maintenance that keeps on being directed at me.

« on: 11 September 2019, 12:17:41 »HG on 3.2 is MLS, so shouldn't rot with abuse like an older composite. But given tunnies service schedule, its possible I guess.
But if the coolant isn't going anywhere else, it has to be going inside.
Coolant fully flushed out 5 years ago, as per GM's long-life. Only done ~35k since then, as I average 7k a year. Cambelt serviced as per schedule annual pollen filter and air filter changes so not sure what schedule you refer to.
There is a clear difference on those spark plugs.

6.9% is a joke, you can easily get 2.9% at Tesco for example. £10k loan over 3 years and cars yours at end of it, think that's what I'll be doing.

So I put my reg into that trade up offer, had a value of £260 if in good condition. £90 if average. 
Not a deal for me, as I previously mentioned you must buy on finance, in the small print:
'Trade-in car must be registered in your name for at least 90 days. Only available on 6.9% APR Representative Conditional Sale and Personal Contract Purchase. Other deposit contributions may be available if you do not have a vehicle to trade in. Conditional Sale: 24-60 month term. Personal Contract Purchase (PCP) : 24-48 month term available. '

« on: 10 September 2019, 20:46:50 »As a fellow coolant-weeping-V6 owner I can offer my own experiences. I'm still in the middle of doing this myself, mine is/was producing a warm/burning coolant smell - seemed to be toward the scuttle, but no vapour visible. HBV seemed dry, then again sometimes a smell seemed to come form the front of the engine, too. Hoses seemed fine, nothing visible anywhere.
With plenum, fuel rail and sandwich plate off, a bolt jammed in one hose, and a schrader valve in the other, neighbor's bicycle pump attached and the system built upto about 15-17PSI I saw a weep from the coolant bridge. Saddening as this was only done a year or two ago, using brand new dowty washers. Of course what's been happening is it's leaking water - no smell... but only after a while then being burned/boiled off as it sits on the block. It also looks like the auxilliary coolant pump seal has gone, though I can't rule out 100% the hoses to it are past their best too.
I had confirmed she was not leaking anywhere, simple process of elimination. Hoses=ok, HBV=ok, header tank=ok, cap=ok, My only other thought was the old oil cooler, however being under there not too long ago, again, this was discounted. After all, cant be the coolant bridge, as that's good as new!
Silly thought - if we are looking toward HG... could a cold pressure test as I did aid you? I'm wondering if you can build the system up to pressure, and assuming the system is holding pressure, would having the plugs out help? if there's something delicate that could be prodded inside each combustion chamber as a 'dipstick' (plastic tie wrap?) - if that comes away with even a spec of coolant on it, you've proved your HG's gone. Obviously depending the severity of the leak you may be talking hours/even overnight.
It's a rather heath robinson/left-field idea, but you'll end up taking the plenum etc.. off anyway to do the HG, so nothing to lose, really.
Might be next stage, but looking at plugs this evening, I don't think that's needed.
Thanks for input though.

I took the plugs out today, on drivers bank. As cylinder 5 gave me miss-fire before. Bear in mind these plugs have done less than 1,000 miles....
Pot One, looking nice and clean: (as did pot3)
Pot Five However
It was slightly cleaner on one side.
Is that a hint of red I see? (i put red food colour dye in system)

I've never used one of these things. Just went to check it now, it's dropped a bit on the morning run. Not normally done that, so appears to be getting worse.
Again no indications where it could be, under the car, hbv area etc. Fact Serek at SOS pressure tested it as well, appears to confirm Nick.W's thoughts on HG

Thanks
Given cost of tools, might very well take you up on that.

Just googled it. EBay review say avoid cheap one at £20. So £50 for decent one?
