Discovery 3 Engine re-build

Great work,again, you'll lose a few pounds working in that heat ! That journal with the plastigauge on it looks to have insufficient oil clearance , I remember in my motorbike days it being a PITA,all the best.

Hi mate yes spot on that was my first attempt three of them come out at bottom tolerance and one below in the end, going to get machine shop advice before continuing checked bearing part numbers fine all marked std, crank and block are both discovery 3, little perplexing at the moment. Maybe this is the reason I could hear a whirring sound, never mind it's all learning should end up with the answer? Yes was hot too much was dripping on motor Lol

After banging my head on the bench last night after work, can also reccomend jamaican dragon stout, came up with a plan refit original mains I marked position and location on removal, cleaned everything and re installed low and behold spot on 0.038 (see pic) going to refit kings just to double check but I do seem to remember a German fella mentioned this, new kings are for 2.7 and marked standard

Great to see you’ve made some progress mate , alas above my pay grade as never done them

Hopefully the results aren’t being diluted from the sweat coming off ur brow with the very hot days

Fingers crossed the rest goes all to plan

As a side note I see the guys got there RRS 5.0 back up and running with a second hand engine, sounded gorgeous

All the best my friend and massive thks as always

Hi yes worked late into night had a nap in the heat of the day Lol re-fitted original bearings in original position and orientation and plastigauged all came out 0.038 or very close all within specification of between 0.030-0.054, then refitting new kings mb4276sv again marked for position I get following results
One 0.022 two 0.028 three 0.025 four 0.025 done multiple times with same results, perplexing no worries will get to the bottom of it, machine shop probably tomorrow will take crank and shells, solutions 0.010 undersized would bring to specification, should know tomorrow when I get them to micrometer the shells which are the only variable in this conundrum considering fia bm1013-standard pic of old shell trying to identify brand any ideas?

@gstuart Sorry mate reference salvage uk yes sounds gorgeous, go on get one you first but don't wait too long Lol, great mechanic too did a really good job, out in the yard too, some extremely difficult bolts to get to but nothing's impossible go on you know you want one all the best

Manage to possibly resolve issues well at least I think so mains caps in picture old shells fit almost flush 0.28 protrusion when flush at other side, new king bearing protruding 0.85 but when I fit in 306dt mains cap same 0.20ish protrusion, seems german fella may be correct, going to go to Searles tomorrow make sure I'm not mad and to make sure I get the right ones most likely fia
