ssn being the Autobahn stormers quarterly magazine.
This is very timely as i've a problem with mine being partly blocked, but thats the thing, the guide shows the atual box itself dismantled with the side plat spotweld drilled out to reveal two baffles.
The shape of the baffles is such that its bot possible for the box to block one breather outlet or the other, as mine appears to be blocked on the smaller pipe only, clearly i've not understood something or i have a differant box design, which seems unlikely as the only differance mentioned in the guide is the gaskit itself which incorporates the flap or is presumanly seperate on later cars, ie mine. Maybe the flap has broken off and blocked mine as the flap is on the small pipe side?
Anyway just wanted to say thanks Andy Clears for his efforts and that having seen that the side plate glue is not attavhing the box to the back of 1,3,5 head but is in fact seperate altogether i'll be having a go at cleaning it out asap.

ps, might have been better posting a thankyou on the abs site but i'm not registered there.
