Personally I don't care... in my opinion 8nm is not tight enough for an 8mm bolt.

I have a friend like that.. to him every bolt is considered 'tighten to yield' I have to keep him away from the tools during reassembly... (It took me 8 years to teach him to stop tightening when something is cross threaded, too.. )

Cross threading is something totally different than stripping a bolt from over tightening... maybe you should try teaching yourself first 

Er. I know that, thanks. I also know the difference between yield in a bolt and stripping the threads out of something. 

That is not what you wrote though

Yes, it is. The section in brackets is an additional comment, unrelated to the first, as shown by the ", too.." at the end of it.

By (over)tightening a plenum to 20nm, as opposed to the required 8nm, could this extra clamping force potentially distort the plenum O-rings, or flatten them too much, and therefore introduce air leaks

(especially if the plenum is removed again in the future, and then re-assembled using the same rings?)

I'm rubber and you're glue...


This could go on for a while folks, best grab a cuppa...

[aaronjb]

P.S. I bet poor amba still doesn't know who to believe at this point..

Better carry on in the General Diss Area then or else we end up in trouble

I shouldn't think the tightness would make any difference as the  o rings sit in grooves and the plenum is bolted down to the inlet metal to metal,the seals are just to be sure its air tight

  Works for me! (Lets face it, most folks torque wrenches probably have at least that margin of error, anyway)

Yours and James' does it seems 

[Gaffers]

I seem to remember 30Nm for these ones, but tbh I just give them a good strong nip after putting a smear of fresh oil on the O rings

[amba]

Well as my internet was down during my refit ,and I didnt have the benefit of the knowledgeable ones advise I have torqued them down to 20nm which seemed consistant with the injector manifold and sandwich plate.
