My AU2, dedicated LPG 4.1 L green motor has a bypass hose running from the thermostat cover to the plastic reservoir over the driver's side wheel. When changing the thermostat today, the brass insert in the aluminium thermostat cover pulled out of the housing (instead of the hose coming off the boss). The housing appears to be good and I can't see any cracks. I've resinserted the brass pipe, added a bit of locktite and pressed it all back together in a vice. The inner end of the brass is now visible inside the housing, though I couldn't press the pipe as far in as the tiny indent on the tube - it would have to go in about another 3mm. Any thoughts about whether what I've done will be enough, or do I need to get another cover or try and find a way to press it in futher? Thanks.
