Thanks Stuart- I have that type of superglue and primer for tricky plastics/rubber. Just seems a shame that there's no flexible glue anywhere for viton!

Evening Andy,
Further to my last email from locktite I gave them the operating temp with regard to superglue, reply as follows:-
I'm so please you wrote back. You are right at the top end of the temperature range of the glue, I don't think it will last.
Loctite 5910 is a high temperature oil resistant silicone based material. This will bond to viton and live in an engine. The difference is that you need to allow 1mm for glue thickness and it needs 24 hours curing before inserting into the engine.
You will get Loctite 5910 from good motor factors (it is used for sump sealing mainly).
Best regards

Hey Stuart, that's very similar to what I do for my coolant seals. I superglue the viton cord then smear some silicone based RTV sealant around the glue join. I've done that a few times in Mazda rotaries without incident so far. Yes the superglue is up towards its limit but not as bad as being bathed in hotter oil.
