My valve guides are a bit sad after a valve crunch episode, the play is too large. The guides were K-lined a couple of years ago. Is it advisable to K-line a second time?
 
Generally speaking? Yes. The scroll liners can be taken out with an expanding reamer and then new ones installed and disrupted. Obviously if there is other guide damage all bets are off.

Thanks for advice, guys! Learning....learning..
My experience is that one need to know a bit of this stuff when the problems arise even though I agree the specialised pro's are the ones being able to make the best judgement. The workshops seem to be increasingly manned by the trainees while the one who known the stuff is sitting in the back room trying to make the accounts tally! A recent example, a friend of mine has just broken crank no.3 in short succesion caused by the grindings of a so-called pro workshop due to wrong finishing at the ends of the journal, i.e. no radius therefore a serious crack initiation. He wasn't sufficiently specialised in these issues to see that it was wrong, (that's why he went to the pro's!)...just trusted them....
