Re: Piston to wall clearance (vitara)
just to add to the discussion: thoughts on a daily driven vitara setup in NY? it get pretty darn cold around here and stays that way for a while. im wondering if it would be too much cold - rattle time for a daily driven setup.

Re: Piston to wall clearance (vitara)
i just measured the top compression ring end gap (with an old ring, dont know if that will make much of a difference) and its larger than .024" which is hondas service limit and what my feeler gauge reads up to. Does anyone know where to get file fit rings or gapless rings for a d series? I looked for hours already.

i had the head off one time and there was some slight scarring on the walls but nothing i could feel with my finger nail...and that was with about 7k miles on the build...we were very concerned with the piston to wall clearance as well but i think its only an issue on cold start up. the vitaras seem to expand nicely and fill the gap.
