Pete, One more sorry. When I take the condensate return pipe loose, shown here. I presume I loosen the connection on the left and leave the "nipple" coming out of the back of the sump in place? Also, is there some type of seal that will need to replace in between? I've ordered new gaskets for the headers (at both ends) and new bolts and washers for the header flanges and of course the two sump gaskets. I hate getting into something only to find out I need another part. Many thanks again.
I am sure Pete will be along to answer your questions in detail but In the mean time I just got around to doing this job on the Stelvio on Saturday. Yes you just undo the nut and leave the nipple, it is a compression fit, you don’t need any seal.
My gasket was in perfect condition at 62k km but nice for peace of mind to have it done, wouldn’t want it blowing on a long holiday trip (not much fear of that this year).
I will do the same job on the GRiSO when she is due her next oil change.

I sort of got forced into checking this. Brought a Tenni green GRiSO with a receipt for a service that had just been done before I brought it. The service was done at 16k but it got to 20k and I wanted to do one myself to bring it back on track with the service manual. Anyhoo Long story short when I tried to torque up the sump plug it just kept spinning. Last service must have over tightened it.
So I knew I had to pull the sump off and get out the Helicoil kit but thought I would have a quick look on this forum for any gotchas and found this thread. Glad I did.
I brought the upper gasket as a precaution and when I dropped the space the gasket had blown out in exactly the same spot as Eire's.
Due to the Aussie Grand Final being on, (USA read Superbowl) I only got it apart and cleaned all the parts up ready for assembly tomorrow.
One thing that I did find a bid concerning was one of the screws holding the pump intake gause filter was missing. It wasn't in the sump so one could only assume it was passed out in a previous oil change and most likely stuck to the magnet. I know it wasn't in the oil I changed.
My question is; are mechanics in the big shops so under the pump these days to get the service times down that torque wrenches stay in the tool box and they could miss a screw in the oil?
Does not give me a lot of faith in them at all.

Before I pull the trigger and order one, is this part also OK for a GRiSO 1100:
I plan to order at TLM anyway and if the GRiSO 1100 from 2007 is also affected by this issue, I'll just add a gasket to my order.

I've never seen the issue on an 1100. The whole oil delivery system is very different on the pushrod models. I wouldn't bother if I were you. Well done for being on top of the issue though.

As always, thanks for your insight Pete! I asked the question because I saw in the part manual that the spacer gasket for the 1100 and the 1200 (2007-2013) have the same part number (GU01003651) so I figured that the same issue might happen with the 1100 (and this would have explained why my timing chain seems to be noisy(ish). But maybe I'm just listening too much and not riding fast enough to not ear the noise.
