Hi guys,
Just had the rocker cover gasket replaced by my local garage,
Left it there for a day to ensure that the sealant was well set,
Now it's home I have checked it for leaks and all seems fine,
My question is,
When I take the oil filler cap off the rocker, while the engine is running,
There seems to be an awfull lot of pressure puffing out of there,
I have only had V6's before so am not sure how much it should be puffing,
I have yet to speak to the mech who changed the gasket to ask if he checked or cleaned the breather pipes, ( Hesse off for three days)
Just wondered what kind of pressure other owners are getting pushed out of they're cover,
I will probably end up checking them myself,
Any feedback would be appreciated.

V6 and 4 pot should be about the same... there's a guide for doing the breathers in the maintenance section

Easy enough to diy if you're able and suitably equiped

Sounds like the small breather hole ahead of the throttle is blocked. The smaller hose from the rocker cover attaches to a pipe which enters the induction tract between air cleaner and throttle. This pipe is necessarily small bore (about 0.080") and gets blocked with oily gunge. Once blocked the cam cover gets pressurised and the gasket blows.
The cure is to unblock that hole. Remove the hose induction tract between air filter and throttle. Remove the small hose from rocker cover to pipe below throttle. There is a coolant collar around this pipe. Try to poke a wire though this hole until you can see it, looking down from above. Wire should be about .065" diameter, the size ironmongers sell in coils as 'thin wire'. If it won't go through, I find that pushing firmly usually shoves out a slug of gunge, which can be seen emerging by looking down from above, most satisfying. The whole blockage can be shoved through until the wire appears.
If you cannot shift it you will have to remove the collar, with its pipes attached, and attack it from the other end, but that's boring, trickier, and fun to reassemble.

You don't need to wait 3 days to ask, he didn't do it, just follow the guide in the how to section

Correcting my reply above, the small breather hole is between throttle and engine, to give it suction. Having read the guide, bear in mid that on a 2.2 you do not have an AIVC. Guide says the pipe narrows to 1.6mm (.063") so you want wire a bit thinner than that. It's worth trying to push the wire through the jet first, it saves so much trouble. I've done it several times.

Thanks all,
I will check out the breather pipe hole and let you know how I get on,
Will prob be a few days as I am on shift work,
Thanks again,
Jiffy

Update on the cam cover pressure,
Checked all the pipes for blockages,
Also pushed a small needle through the hole in the small metal pipe that is sticking out of the throttle body,
Didn't get any resistance when I pushed it all the way in,
Could feel it going through the hole,
And hitting a solid part on the other side,
Refitted the small pipe and sucked and blowed in it,
Didn't get any air when I sucked or blowed down it,
Maybe have to take the throttle body off and have a good look see on a bench,

FFS, just rip it all apart and give it all a good clean.

The 4banger seems to puff even if the jet is clear,  it puffs from the metal sump pipe. Probably the best thing to do is fit a flametrap then maybe go for a catch tank but it's a tad extreme.

I'm sure the redtop used to puff also

[JIFFY]

Thanks for the advice guys,
Flame trap seems like the obvious solution,
Any reccomendations on what would fit without too much trouble?
Awesome replies as usual,
Jiffy

Flame trap not the route to go, need to solve the issue. You had not issues before you took it to the garage?

I'd be taking it back 

Sounds like they have not reinstalled the gasket right 

Given how easy it is to work on the cam cover on 2.2, I'd take it off inspect and refit.
