Looking in the hole directly below (but about a foot under) the pilot motor fuel tank, at the clutch - the engine is on the right: http://www.classicmachinery.net/forum/images/post_img/19364808174e80302793d20.JPG URL of the original image: http://www.aussieheavyhorses.com/ASSETS/Fiat-50L-55L-crawler...

More photos: The top of the head, after the rockers have been removed: (One head bolt undid from the bottom, and the brass acorn-type nut is still on. You can see it in the bottom, at around the 7-o'clock position) http://www.classicmachinery.net/forum/images/post_img/17492817964e8030076ef4f.JPG URL...

Thanks, Deas for the hints. The two head bolts are broken off attached to the block, which is a sort-of hollow shell, rather than block. They're not in the head. The bolts are also threaded at both ends, with a bigger thread at the bottom-I'm guessing maybe a metric 14mm, and a 12mm at the top for a...

Hi Deas, thanks for asking! I had checked that GW website out & emailed them about five weeks ago querying a head gasket...and they said they actually have NO parts that's suit us... Nick has dissected a lot & found nothing that suggests a problem to us, except that two of the head bolts bro...

Thanks for the reply, Deas. A friend suggested maybe thrust washers/bearings might have donated those broken parts-if there were any. Nick has pulled the oil pump apart, and it all looks 'normal' - nothing abnormally shiny nor missing. No apparent valves there either- just castings/housings, the dri...

Hi Deas, thanks for the interest! It took Nick a while to get it jacked up, supported, and then get the front springs off & the sump off. We/he ended up using some stumps, and some railway line to bridge across the stumps, so we could still wiggle under the radiator to get in underneath. We jack...

Thanks Deas, actually, we do have a 'proper' mechanic's stethoscope with a couple of feet of plastic tube between the probe & the Y- inherited from my father-in-law only a couple of months ago along with a nice old Nuttal lathe & a biggish 3-phase drill press. It's just that using the stetho...

Hi again, it's a different piece of advice we're looking for now... (*puts cap in hand*) Our son, Nick, managed to scratch up most of the paddock with the Sundercut, except for about half an acre and by then it was too dark to see, so he stopped. The next day we had 15mm rain, so there it stayed &am...

Thanks again for the feedback. Mick, the original poster contacted us re getting some injectors for his 50. I've photographed what we have here, for his information or benefit. The injectors on the 55 are a bit different... These are from the 50L: http://www.classicmachinery.net/forum/images/post_im...
