Was read around that you can make a fire box for the air vent from the engine breather to the lowe pipe to the bottom breather in air intake, its the thin pipe, somthing about making a fire box will stop the pipe from blocking up all the time, dose any one know what i mean and how to make one thanks

Someone on here - I forget the username I'm afraid - has fitted a simple (plastic/paper) inline petrol filter in that hose, the type carb-engined cars tend to have; a couple of quid from any motor factor.

I believe he had no problems with this, and it did collect a fair amount of crud that would otherwise have ended up clogging that little jet under the TB.

Been meaning to add one into ours, might do it tomorrow [make that later today  ].

thanks i did not know if that would work as the pipe dose get hot, i will try that thanks,

Reading your post on the oil thread, you use castrol magnatec, firstly don't belive all the marketing bull about that oil.

There is one very good reason that pipe is always blocking up, shite oil!

I use GM Semi Synth, and after 5k, that pipe still super clean and not clogged at-all. You should not need to bother installing any kind of firebox as long as its maintained well with quality oil.

In fairness, Tunnie, there could be another/additional reason.  The OP and myself have much older miggies than yours, and will tend to suffer from more blow-by and so the breather system will have more to do.

A lot of these early motors have seen less-than-optimal maintenance in their early lives as fleet members etc. and it can take some time/care to get them back from 'close to black death'.  (e.g. the pics of the inside of your camcover in your gasket-change guide were almost unrecognisable as the same item as on mine it was that much cleaner/newer looking).

Having said all that, I use Vx 10W40, and wouldn't bother with anything else. 

@rusty: I was also thinking that those filters aren't really designed for filtering a mixture of oil mist and exhaust fumes, but as I said, the guy who posted on here about it hadn't suffered any problem (he posted again a year after fitting it, to say so).

Sorry yes there are more, i did say "one" very good reason! 

Its the most common though, castrol oils are known to cream up more than others, V6 oil cap is a good example.

Switch to GM oil and i bet it says clear for longer 

[TheBoy]

seem to recall GM sell the firebox as a modification.  Of course, I could be talking rubbish again

[Abiton]

Not rubbish at all, The Boy, just for a different breather pipe, the one from crankcase to camcover:



I've absolutely no doubt that fitting this will help with keeping the oil in the crankcase where it belongs though, instead of clogging the other breathers, and that little jet under the throttle-body.
As far as I can make out, the GM part number is 9 193 502.  Can someone confirm?

[Jimbob]

I thought the 2.0's came with them.

I fitted one to our old 2.2, due to a knackered hose, easy way to fix 

Vauxhall sell em 

oil seperator was the official name iirc

I had one of these boxes in my boot when i bought the car,wondered what was for and went.My car has  what looks like a small K&N cone filter fitted.

[rustym95]

no its this pipe with the arrow. no mater what oil is used it all ways blocks up at the end of the pipe where the hot water gose round on the case of the air intake.

Thats one - never seen anything on that before

How often do you clean that one out? I'd be cleaning that annually.

every 2weeks or so, its not the pipe its the heat ring keeps blocking up had it to bits b4 and there is a heat ring the pipe gose in the middle then into the air intake, aways blocks up at the heat ring.
