Hi Folks,<br /><br />Im rebuilding my inline at the moment trying to cure a water ingestion problem.<br /><br />As I had to remove the pistons from the block for the machinist to do some work I have decided it is best that I hone the cylinders before refitting the pistons so that the rings re-seat.<br /><br />I had between 140 and 135psi on all cylinders before tear down and would like to ensure that the compression is still good when I put it back together. <br /><br />I have a 3 leg cylinder hone that is brand new with 240 grit stones. I have gently honed cyl number 1 using WD40 and 2 stroke oil as a lubricant. This has exposed slight vertical scoring on the bores that I never knew was there. It is very slight and I was unsure as to whether I should be concerned by this or not. Should I continue to hone until its gone?<br /><br />Any advise on the honing process would be greatly appreciated, how long should i hone for etc.<br /><br />Warm Regards<br /><br /><br />Stan
