I fitted some new core plugs onto my block today the 1st of the 3 went in about a mm passed flush on the block and the other 2 i left flush ! Should all 3 be flush or slightly passed flush and should i have used some sort of sealant ?

Im not bothered about doing them again if need be just want to know if ive done them wrong or not with it being my first attempt at them !

fitting them just under flush is fine mate, its worth using a jointing compound to make sure there in nice and snug

Nice one thanks for the advise ! Ive decided to take them out and get some more re do them with well seal or similar !

Ive had a go now so more confident in doing them again

I've not changed a core plug for years, but always thought they were interferance fit,
