Just wondering how many of us lube the group head seal on a regular basis and if so, how often and what do you use ?
Ive started applying rice bran oil with a cotton bud every night after shut down. PF now locks in beautifully with ease whereas previously it always felt a bit stiff regardless of dose. I just put it down to it been a new machine and leaving it on all day with the PF just engaged in the group head whilst in stand by causing various bits to expand. Your thoughts ?
