overflow after nozzle change

I changed to a ruby 0.8mm and it leak at top of nozzle and heat break

I have screw in the nozzle as close to the heat block as possible and I still get overflow.

what should i do?

Thanks

Best Answer by KTH:

it was still leaking.
so i reseated heatbreak, heatblock and nozzle.
end up changing to a new heatbreak and heatblock as it was a pain to remove&put back the other parts.

hopefully it does not leak now.

Leason learnt:
Do not change nozzle unless you want to have the change to reseat the whole thing.

Your heat break may not be screwed in deep enough to form a seal.

i screw in even more n having a LITTLE gap left.

that solves it.

i was planning to reseat the whole thing if this does not work. luckily it worked.
