Theres a tiny bit leaking from the cam seals which I have removed and will replace, but I cant figure out how the hell im supposed to replace the double half moons, as they are the main leak.
Dont tell me I have to pull the whole head off

Cam carrier needs to come off. Gotta remove all the 12mm bolts on the cam caps if you haven't already done so then give the cam carrier a couple taps upwards with a rubber mallet around the sides to remove it.
It is sealed with high temp silicone RTV
Be careful when removing it though as if there are any loose collets on the tappets they may fall off into your engine.
When putting it back on you will need to run a bead of silicone (Permatex Ultra Grey or similar) around it and then torque all the 12mm bolts back to spec (24nm)
Take a look at the workshop and engine manuals available at

They tell you everything you need to know including torque specs.

Ohh i see, ye I had all the bolts off and the cams out but i didnt know that whole top piece came off, ive tried giving it a smack with a mallet but it doesnt want to move, any other methods to get it off apart from jamming a flathead in the gap and hammering it in, dont want to damage the metal though

Give it a harder smack with the mallet. :lol:
Just make sure you're using either a rubber or wooden mallet as to not damage the cam carrier.

Make sure once you crack one side you move to the other side as it has locating dowels.
Once cracked you should be able to wiggle it off.

oh man, finally got it off, was whacking away at it for like 20minutes ended up sticking a flathead in there to get it started, got one end of pretty easy then the other side i spent forever trying to get it apart till i realized there where 2 bolts on the side that where holding it on to some small plate of metal.
Anyways thanks for the help

Ye ikr, I really didnt want to but it was such an awkward angle to try and hit with a hammer and I srsly couldn't see it coming off any other way. Ill make sure I'm extra generous with the liquid gasket in the areas I did it.

Be extra generous with thinners before using your gasket goo.
