Hey Ed, how's the build going? Out of interest how did you diagnose ring wear?

[daviee]

easiest way  is to place the ring in the barrel and measure the gap you do this in two places one about a inch down from the top of the bore and second about an inch up from the bottom that way you can tell ring wear and bore wear

That's what I expected, a full teardown head off job. I tried to test my compression with a kit I bought to test my Yanmar marine diesel. https://www.amazon.co.uk/gp/aw/d/B00KCLSSVK/ref=mp_s_a_1_2?ie=UTF8&qid=1510596209&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=diesel+compression+tester&dpPl=1&dpID=51lvnfmgwlL&ref=plSrch this one to be exact. But it didn't have the correct connector.

Hi Mate , rebuild is going well (so far) , top end of the engine is at the engineers for a head skim and reseat of the valves and i'm having the bores honed prior to fitting the rings , Im just waiting for an engine gasket and seal set that seems to be taking ages to arrive. I did a compression test with my father in law , compression was down on 3 of the 4 cylinders but temporarily came back up when we squirted oil down the bores , which my father in law (who knows more about these things than i do) diagnosed as Ring wear , which was subsequently confirmed by the guy whose skimming the Head.

Repeat the above process with new rings to determine if the bore requires replating as they are nikasil plated bores, don't forget to check the ring side clearance, with the old and new rings.
