After a delay of a day I'm finishing off putting my car back together after changing the head gaskets. Noticed that the breather hose on the RH rocker cover to plenum was slightly split (or it was probably weak and split when I pulled it off). Cheap enough from Island 4x4 (https://www.island-4x4.co.uk/rocker-cover-breather-pipe-plenium-llh500090-err5038-p-5924.html) at under £2 but with postage that would probably put it up to nearer a tenner. Figured I may as well get one from LR as I would be able to order it from my local main agent and pick it up the next day, so checked their site. In stock and available, no problem, then I saw the price https://parts.jaguarlandroverclassic.com/llh500090-hose-assembly-breather.html?code=60977 for a 6 inch long pipe?????
