That is a Tomic part number. Manufactured in Poland. It'll last but nowhere near as long as a genuine gasket. No need to change the head gasket. You need the black sealant though to seal the corners of the half moons and front riser corners.

Thanks for your advice and offer mate  i appreciate it.
I've just found the link on how to, so'll have a go tomoz since the in laws are coming round    , good excuse to get out of the house 

[Welung666]

Just to add... did it come with the O rings as well? If not you'll need to get them as well. Only tighten the cover down to 8nm when refitting as they will continue to leak if you over tighten them

[cube]

Yep came complete with the o rings, you've just reminded me i need to treat myself to a small torque wrench, a late xmas to myself 
lol lol lol


Thanks again

While you're in there check your HBV, most likely source of your coolant leak.   

[cube]

I've found the hbv link, reading actually lol, am i looking for leaks at this stage or looking at replacement

[Kneepad]

Looking at your first picture it appears to be coolant dripping off the coil packs.
Primary suspect HBV. Replacement is the only option. Unless you can see anything else i.e. split or loose hoses.

Its oil dripping mate on the coil pack

Well I have just had a look at this for cube and there is a lot of pressure in the cooling system and a distinct smell of exhaust fumes in the header tank, so unless these engines have an egr cooler which I dont think they do I am putting my money on it being the head gasket. Just need to find somewhere near Bradford to get it skimmed

Pressurising of the cooling system (particularly before the engine is hot) may be caused by a failing head gasket.

Have you done a compression test? If the readings are still normal  then I would want to get the head off and inspect it for damage before deciding it needed a skim.

[scalli]

Haven't done a compression test, but then again you can often get a good reading even with a failing gasket. From the amount of bubbling in the header tank I am guessing it has blown between the fire ring of one pot and a water gallery

4-pot tends to go @ waterjacket on #4 cylinder

I am guessing you are right (you didn't mention the bubbles)

[scalli]

RobG I am guessing you are right, just found a picture of the headgasket and it looks like there is a water channel very close to number 4 pot. With it being that close I think a skim is in order as a couple of thou distortion would lead to it going again
