Ah, thanks again Bryan - and nope, didn’t see any scoring etc of the seal seating area prior to the new seals going in. I too reckon OEM would be better, though tbh I can’t remember if the seals were... or weren’t. (And yep they were seated closed side up, ie part # exposed...)
The manuals just state an interference fit... should I add in some kind of goo / sealant, and if so... what?
Ta muchly,
Simon
