    MVVS 2.5D RRV

    Hello Pe

    I would be grateful if you could answer some questions about this engine:

    1. Will the piston and liner set for recent production MVVS 2.5 diesels fit OK in this engine?

    2. Is a factory header available?

    3. If so, does the usual pipe for the 2.5 engine will fit up to it, with the supplied silicone coupling tube?

    RE: MVVS 2.5D RRV

    I located a piston and liner for a current spec 2.5D. They fit the above engine perfectly.

    Porting and timing in the new liner is a little different. I ended up leaving in the old liner. It must not be overly worn as the new piston makes a nice gas seal using it.

    The old conrod was unbushed. Both little and big ends were worn. The current spec conrod (supplied fitted to the piston in th enew P&L set) is sturdier, and bronze bushed on the big end.

    All fitted up with no issues, except I made a thicker back plate gasket to stop the crank pin binding on the disc valve. Valve clearance is good, no scores on the mating faces.

    It's looking good.
