ran car and oil is  pizin out at the back (2 half moons) what the hell happened here 

[martin42]

did you use black sealant on the half moons and also you should feel a lip of the gasket where it fits over the half moon

Half moon probably came out of place when putting back

Half moon probably came out of place when putting back

thats only thing it can be but why not leak with old oil in it...

[Webby the Bear]

The gaskets sit in there nicely.... but they will easily fall out.

i was quite liberal with the sealant (not OTT) and then i've heard a tip that you can put a little mirror behind the cam covers to check the half moons are sitting correctly.... i personally didn't do this.... i just felt at the back but you could try it.

also, i wonder what peeps think about putting a tiny bit of sealant in the cam cover corners, under the gasket to hold it in place during installation? just an idea 

[Steve B]

well been vx and bought another....just dont understand why it waited for new oil b4 leak

[Webby the Bear]

Is it possible you dislodged when you cleaned breathers? 

[tunnie]

Easy for the half moons to not seat fully back when refitting, can't see them shifting afterwards. Did you check half moons after fitting? Use black sealant in right places as per the guide?

[Webby the Bear]

That's what i thought.

CC bolts torqued to 8nm?

[Steve B]

no..breather was done first..mon.
then cam gasket    ..wed....
no leaks
then today new filter  and oil   and the big leak

was thinking i done job wrong with gasket and nice new oil finds leak..
maybe a bit higher oil pressure.

all i no is it gotto come off again

i did use sealant vx i followed the guide on here
