Do four, "LINERS" make a cruise company or what any honda owner shouldn't see

NOTE:- you are supposed to have the top of the block milled after this AND rebore the liners to ensure concentricity and perpendicular to top surface.

With a flanged toped liner, as long as the liner and liner flange and alloy barrel and barrel seat are meticulously clean, there should be no need to bore or machine, Ive changed more liners bot wet and dry, flanged, pegged, stepped, screwed, and pressed, some so big it takes a hoist to install only the pressed ones have a need to be machined and dressed, one thing i Would do if i was to say get a set of liners made up for the mock motor for later use would be to cross hone it lightly and to check ring clearance. never had a seizure/rapid wear/total failure/blown gaskets/ etc but then Ive been mechanically minded since obtaining an nsu quickly at 7 and fixing it by myself then on to college for the finer things...
Bryanj:
Theory says yes you is right but originaly the liners are fitted then finish machinedso changing from one block to another can cause mis alignments even with stepped liners. done many a Bristol BVW twice
matthewmosse:
Knowing Hondas they'll swap over because of the production line method of building, Britsh engineers from the likes of Bristol hand crafted each engine individually so swapping and changing is I understand a somewhat fraught expirience
rigwit:
Try doing one of these and yes the plates on crankcase do unbolt off you can stand up inside it............ its all the same realy just a matter of scale and a few inovative parts/way of doing things they also did a v16 but mainly marinised them

Thats a baby one, ever played with a doxford?
