EliTR6 Posted December 19, 2021 Report Share Posted December 19, 2021 Hi all, A DPO must have broken off the vacuum hose nozzle on our mini's ECU. It was badly superglued in place and broke off with minimal pressure. What would be the best way to repair this? It sits in the engine bay so must be temperature resistant. Thanks!

Ransomes256 Posted December 19, 2021 Report Share Posted December 19, 2021 Plastic glues are very difficult to identify as they vary with the many plastics out there. Personally I would suggest opening up the bore a little and inserting a thin wall brass tube (available from model shops or on line) into both halves and then use a 2 part adhesive (like araldite) around the outside to hold it together.

iain Posted December 19, 2021 Report Share Posted December 19, 2021 (edited) I’ve recently found Hafix. Seems to stick everything so far. https://www.hafixs.co.uk/products/profglue/index.html No association, just found it to be very good.

RobH Posted December 19, 2021 Report Share Posted December 19, 2021 Neil's suggestion of a metal reinforcing sleeve is the best way. A plain joint will probably fail whatever glue is used. Quote Link to post Share on other sites

Regards Neil Thanks Neil, genius! I've ordered some brass tube online with a hand drill to ream out the id to the correct size. I hope to be fitting a stage 1 kit over the holidays so it's annoying to be held up by such a small part! Quote Link to post Share on other sites
barkerwilliams Posted December 20, 2021 Report Share Posted December 20, 2021 Lightly rub outside of brass tube with abrasive to score the surface and assist the adhesive. Brass is often coated with light oil, strip that with brake cleaner or similar. Alan Quote Link to post Share on other sites

lynchpin Posted December 22, 2021 Report Share Posted December 22, 2021 Hi Sleeving it is a good idea could you also carefully trim back some of the plastic on the outside ribs and put a jubilee clip over it as extra support? Phil.. Quote Link to post Share on other sites

Regards Neil +1. That was the recommended dealer repair, rather than replace assembly, for the Rover plastic radiator pressure tank when the inlet hose connector broke, until the tank had a brass tube moulded in at production.
