skeggyrik 3 Posted October 16, 2007 How long does the cross hatching effect seen on new and freshly honed liners last in the bores? I ask as on removing the head on my Mi it is clearly visible all the way around the bores. Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted October 16, 2007 I've stripped engines of unknown history with 140k on & they've still had the cross hatching visable. Graham. Share this post Link to post Share on other sites

welshpug 1,657 Posted October 16, 2007 it could be that its been apart quite recently, but then again from what Graham said they could have been there for a Long long time! Share this post Link to post Share on other sites

Miles 331 1 Cars Posted October 17, 2007 Good question, Depends on many thing's, Like Graham I;ve found engine's which have been abused to hell and back and have found the liner's fine with the cross hatching still very much visable, But other's which do more town work seem to suffer more. So saying a milage is pretty hard, so around 170k plus Share this post Link to post Share on other sites
