ran car and had good look around no leaks job done.and ran car for 2 days...no leaks all vx parts
went out today on drive put new vx filter on and 4.5 ltrs of there semi syn oil
ran car and oil is pizin out at the back (2 half moons) what the hell happened here :'(
-
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 :y

yes used the vx sealant
done the breather clean off the one on here
-
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...
-
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 :)
-
well been vx and bought another....just dont understand why it waited for new oil b4 leak
-
Is it possible you dislodged when you cleaned breathers? :-\
-
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?
-
That's what i thought.
CC bolts torqued to 8nm?
-
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
-
Did you clean the breather box .

no .tightened them back up to what i thought felt about right...had only giant torque wrench
and guss what i just bought from screwfix few hours ago small torque wrench £35

It's quite hard to judge 8Nm, it's a very small amount. Possible you over squashed it at the back
-
yes tunnie think your right..well gotto do it again... with new torque wrench

I suppose if BTC over tightened then the effect would be that the outsides of the cam covers lift up whilst the middle is compact.

Yup, it would squash it out of shape. You only need a pin sized hole for it pish it out at fair old rate.

got a mirror on it and torch half moons stick out about 5mm from cover face..bet someone gonna tell me they gotto be flush
its got to be down to my rubbish fitting...only thing it can be
-
Yes, should be flush with cam cover, at most sticks out around 1mm.
8Nm is the tiniest amount, it's a lot less than you think.

Easy to do :y
First time I did it, moons did not seat right. Only spotted after I torqued everything up, taught me to double check!
-
You can probably re-seat the gaskets rather than buying more - as long as they haven't got caught somewhere and damaged.

Definitely check the gaskets before taking the new ones out the box.....they could be fine and then you can get a refund on the new ones
