What is that sound?

[Biotoxic]

Is it a gasket or cylinder head gone bad?

How to say this without upsetting yer ...

Sounds like yer HEAD GASKET HAS GONE BYE BYES..... the noise is either Blowing Bubbles INTO the Tank or Sucking water OUT of the tank Either way its HG FAILURE!!!

& the Colour of that Water around the tank would suggest to me that a REET GOOD FLUSH may be in order .. (You MAY just have a Blockage in one of the Galleries) causing "Localised" Boiling ect ect ....

I was going to comment on the colour too .. if your coolant is that lovely "rust brown" .. its probably overdue a flush!

Hit your local Indy garage (well, any "good" garage really .. A lot have a funky machine that can "sniff" the gases in the header tank and tell you if your HG has gone or not.

I can smell exhaust fumes :)
that rust colour is because I use water, its too expensive to add 0.5 litres of antifreeze to every 45-60 miles :D I am using water for about 3-4 months now. that's why its.. rusty. At least I can see where I need to tighten some bolts for bleeding the air out of the system. I think that I would be able to see where exactly water was leaking inside the engine(head gasket or not)

Well, there you go .. I think you've pretty much diagnosed it .. Slow HG Failure! :thumbs_up:

Is it over pressurising as well? Only asking because of the brown liquid that looks like its come out of the header tank.

[Biotoxic]

yes it did, mostly when I removed that cap, water was gushing out.

I had similar problems to this on my Rover. It turned out to be a crack between cylinder 2 and 3. I was using between 1/2 to 1 litre of water every 4 miles.

Hi,

As above really, but another simple test, take the lid off the header tank and put a condom over the threads, start the engine and if it starts to fill with air, it's pretty much deffinate HG failure.

Bio, just before you go off rippin the head off .... Try this >>>>>http://www.irontite.com/

I can HIGHLY recommend it I did the HG on my Range Rover V8 whilst on Holiday in Wales a few years back & (Just as a "stop Gap" measure) I spent an afternoon or two putting Irontite in (Just to get me back home) I was towing a large Caravan & running on LPG The caravan put a huge strain on the engine & the LPG made/Makes it run Hotter anyway .....


I got it back home & TBH I couldn't be arsed to rip off the head so I just left it & for 2 & 1/2 YEARS that Rangie ran with NO PROBS AT ALL I/we musta done 20K in it AFTER the Irontite was put in & it NEVER FAILED ONCE!!!!

& its STILL goin strong today (I see it once in a while down in Liverpool) ..

BLOODY DAMNED GOOD AMAZIN STUFF is IRONTITE!!!!

I have a spare skimmed and pressure checked cylinder head, It's just a cylinder head swap, engine block head is skimmed as well, should be perfect fit with original volvo gasket :)
