Does the kit from Island 4x4 include replacement seals for the refrigerant pipes where they attach to the compressor? Or are they not required?

I don't think so, looking at the picture it is just the valve and circlip.

Can anyone confirm that for the L322 LM 2010 - 2012 the correct compressor oil is PAG46?

The TSB states the cause as the valve being worn although I understood that it was a valve design issue, now rectified, but possibly prematurely worn due to a design shortcoming. |

Yeah, given the number of hits for this same issue on VAG cars using and having issues with PCVs, I would agree with Graeme that it is likely an issue with the valves.

OK, work is under way.
In this pic, you can see the electronics that sit over the airbox sat on the strut. One bolt out (on right of pic where white wax oil is), unplug the connector on the pipe, and undo both clamps of pipe.
next remove the airbox to turbo pipe,which covers the aircon pump. This is bolted to the rad cowling which needs removing first. It also has a smaller pipe on the back side of it that needs it's clamp undoing, plus a small pipe clipped to it in 2 places.
It also has a clamp at the other end, that is a bitch to get to. If you zoom in on the pic you can just make it out.
Jobs yet to do: The ribbed belt will need to come off, though not entirely. I might have to remove a coolant pipe, we shall see. Then unbolt the aircon pump. Whether I can actually remove it completely is questionable at the moment. Jobs being avoided: To actually replace the belt you need to remove a pipe on the drivers side as it's support bracket is within the belt. Also remove the cooling fan belt, which is a stretchy one, and is usually cut to remove and replaced. That means rad and cooling fan out. Trying to avoid having to do that ![]() Rain has eased, back it ![]() 2011 4.4 TDV8 AB Black Last edited by John w on 10th Aug 2018 2:41pm. Edited 1 time in total |
