    Chris,

    Yes, back up now, probably as Paul suggested, server down

  • Lawrence Slater13 February 2016

    Guy, if you only want 30k miles more, I'm guessing you don't want to spend a lot on the engine.

    I wouldn't even bother to measure the ovality of the bores, or worry about and wear on the pistons.

    Hence, work on the assumption that as there is little or no visible evidence of scuffing or wear in the bores or on the pistons, then perhaps there was too much clearance to begin with, and ...

    Yes, thanks Lawrence.

    I am always confused by your "see mine below yours" As your thread trail seems to be upside-down. My screen always shows the most recent message at the end of the discussion.

  • Lawrence Slater13 February 2016

    Correction. I've just remembered. It wasn't the width of my oil control rings, it was the DEPTH. I couldn't compress the rails into the bores.

    I used a GRANTS ring set. About 35 quid. All you need to know is the dimensions of your rings.

    Here's a gratuitous shot of mine, cleaned up and ready for rings.

  • Guy W13 February 2016

    No evidence of piston scuffing on the sides near the wrist pins. Quite the reverse if you look at the photos Lawrence - from he blow-by there would appear to be too much clearance there!

    I will shoot off an enquiry to Thorntons when I have sorted out exactly what I am asking for.

    One thing I am not at all sure f with this is what sort of level of accuracy measurements need to be to? ...

  • Lawrence Slater13 February 2016

    You posted as I did Guy. See mine below yours.

  • Guy W13 February 2016

    Cannot afford one of those for a one-off job Dave!

    I will try Richard's suggestion as I do have a couple of spare unused rings from the same piston set. But I am not confident of accurately measuring the ovality with a feeler gauge between the ring and the bore. Trying to slip a flat feeler gauge between two curved surfaces doesn't seem very practical.

    Would one of these be any good?...

  • Lawrence Slater13 February 2016

    Ah yes Guy. I remember now. You had a complete spare piston didn't you? Just measure the rings, width and depth. The give Thorntons a call. Pretty sure they'll be able to match them for you.

    But actually, unless it's an 'off the shelf' ring set, it may actually be cheaper to buy 4 new pistons. However, being +30, you'll have the same issue I had. Nobody makes +30 pistons anymore. Hence I re...

    Yes, looking forward to your new adventure, Huib

    Just on the off chance... anyone in the Staffordshire area able to, or know of someone that is able to, weld aluminium?

    Cheers,
    Malcolm
