Whilst we're on the subject of breathers; does anyone have the part No. for the "O" rings where two the boxes connect?

Mine were missing when I did them recently.

Why Sealey...

Because it was the cheapest... by far. Teng do great tools, but the equivalent wrench is around £40, and I think the equivalent Draper one was over £30. Incidentally, I have two other Draper torque wrenches and they seem well built (definitely better than the Clark one from Machine & Mart).

The reason I went for the cheap one by the way is that I bought it specifically for the cam covers (although I did find-out since that also the throttle body bolts are 8NM), and I don't think that the absolute accuracy is important e.g. it could be 7.9 or 8.1NM, what is important is that (a) they are not too tight - bolting plastic into alloy to hold down rubber requires very low torque, and (b) more importantly that the torque is exactly the same for all bolts so that the covers don't get wrapped.

I have a good unit to cover the 10-80NM range, which is good for most bolts. I use the Clark for the wheel bolts which are 110NM, and this is good enough for that. I buy expensive tools when it makes sense to do so, but I already have three torque wrenches apart from the 5-25NM one so I didn't think I shopuld invest in a Teng wrench just for the cam covers.

Hopefully Sealey will fix it.....

The bit I would replace if I need to do this again is the black plastic box on top of the plenum (it is actually under the ecotec logo, which can be prised off). As for the metal box at the back of the drivers-side cylinder head, Ronnie's guide said not to remove it, a recommendation I was only to happy to follow since the thing is almost inaccessible even with the plenum removed. In a perfect world then yes, this is part of the breather system so should be removed and cleaned, but I just cleaned it carefully in-situ while remembering TheBoy's warning that the small tube should be cleaned gently as there is a diaphragm underneath it...

I spent well over two hours just trying to clean the black breather box (and I have two of them due to the 'long plenum' - found on the 2.6/3.2 and on some late 3.0), and it is now clean but not as good as new. Also, there are two very tiny holes under the black plastic box, that you can hardly fit a needle in. These and the ducts leading to them are impossible to clean in a way that will guarantee that they don't get clogged-up again quickly.

So if a new box costs say £20-£30, then it would be worth it in opinion to just get a new one if the breather is badly blocked.

Funny - I never thought of Sealey as cheap and cheerful.  Actually the only Draper one I can find is this one at 70 quid
http://www.justoffbase.co.uk/Expert-Ratchet-Torque-Wrench-58130-Draper-EPTW5-22

and that's way too much  (like you, I have a good wrench already that does 20Nm upwards).

I am inclined to agree that applying consistent torque assuming half decent accuracy is most important in this case.

I am currently considering this one
http://www.justoffbase.co.uk/s.nl/it.A/id.34303/.f

Its 3/8" which is what most of my sockets are, although I do have a cheap 1/4" set.   Would you see any merits of the 1/4 over the 3/8?

Cheers,
Ian
and just for a laugh - for the price of a couple of Omega's you can have one of these:

These may be of interest although they do not actually show the O-rings.... they should have been near where the number '7' is on the drawing.

I will find out the cost of this tomorrow and report back.  I hope that I did not give the impression that I was questioning why you bought Sealey - I am interested in purchasing a wrench myself - I have one at present but it is not that good...  I agree totally about purchasing expensive tools.

OK, thanks, so these are no 8 & 11 in the drawing then.

I will need to check my sealey wrench before passing comment.....I have found it pretty good and it locks off quite nicely, plus its what I could afford at the time....

[Markjay]

By the way, I did take pictures, but both the cam covers gasket and the breather cleaning are already covered in the Maintenance Guide section, so I only posted the bit about removing the plenum on 2.6/3.2 which is a slightly different procedure to the 2.5/3.0:

Its 3/8" which is what most of my sockets are, although I do have a cheap 1/4" set.   Would you see any merits of the 1/4 over the 3/8?

The Sealey is 1/4" drive, which is not ideal for me since my Torx sockets are all 3/8" or 1/2". I should get an adapter, but in the mean time I am using standard (i.e. not Torx) 12-point 1/4" sockets - for the smaller sizes and low torques it seem to grip well and work fine...

[ians]

The Sealey one I was looking at was 3/8 for exactly the reason you mention.

I also found this as Teng seemed to be highly thought of:

Decisions...

I went to the dealer yesterday to collect some other parts that I had ordered.  They weren't in which means I cannot start work this weekend after all.

I inquired as to the price of the breather box.  If you purchase retail, they are priced at about £51.  On TC they are £40.  These prices are ex VAT.

For the sake of £40, I ordered one up and will fit this when I do my Breathers, Throttle bodies and plugs.

Not got an invoice yet, so can't quote the part number, but the diagram posted above should help with that.

Hope this helps
