Omega General Help / Re: Sparkplug Tightening Torque

« on: 20 September 2010, 18:09:30 »

Spark plug torques have been a problem for me too.  In my Haynes manual for a 2.0 litre SOHC it says 25 Nm for "spark plug heatshields".  My car though is a 2.0 DOHC and in that section in the manual no torque is given for spark plugs.  However, in the information that came with the plugs I installed a year ago (BOSCH Super 4 520 FR 91X) it says 28 Nm.  My torque wrench is scaled in kilogramme metres not Newton metres.  28 Nm is 2.855 kg m.  The lowest mark on my torque wrench is 3 kg m and that's what I used for the recent second installation of the same plugs.  (The crush washers are already crushed)

I noticed that when I removed the plugs they released very easily, as if they had not been as tight as they should have been.  I am guessing that after first installation it would be a good idea to go back to them withing say one month and retighten them.

Omega General Help / Re: rear door permanently locked

« on: 20 September 2010, 18:23:07 »

I had a locked rear door problem which was nothing to do with the door lock motor.  The door had been a bit problematic since the car was new.  It would often not open from outside, but if I bumped it from outside with my backside, while lifting the handle it would then open.  It was always possible to open it from the inside though. Eventually it failed to open and as luck would have it that was after I had set the child locks so that it wouldn't open from inside.

So, with a cut off hacksaw blade, after checking the position on the other door, I was able to move the child lock lever from inside the car and get the door open.

Then took off the inside door lining, and found inside the door, that a plastic nut, which has to be positioned so that it engages with the outside operating lever, had moved on its spindle (because the internal thread had stripped or not been sufficiently well engaged).

The solution was to screw the nut to the correct position and put superglue on the threads.  There has been no problem since then.

I'd like to add a photo, but don't know how to do that.

Well, here I am in yet another forum.  Why - well my Omega is hesitating and I think I've tried all I can think of except the EGR valve, which as you probably know is difficult to get out.  Is it worth it is the question?  If I get it out can I fix it by cleaning it?  Or do I have to get a new one?  I read about blanking them, that may be a last resort, but I'd prefer if it worked.
