Welcome to Landyzone nice looking landy what kind of camerawork with car do you do

That’s what I wondered as I did the 4 extra bolts in the bottom for the 200 di, so are you saying even with the di it’s over stressing the series gearbox

Interesting does the 300 mate to the series gearbox directly, or is adapter needed, I’ve got 200 in mine and that’s pretty much a straight fit

Were the ring gaps equally split around the circumference. Is there some black marks in the cylinder pic running down Have you honed the bores after new rings

Not sure but you’d get a very tight hub nut 😀

Was small ends on pistons checked

I would think if you have checked everything while engine out and all looks fine then reinstall, but was there a question over gearbox noise , so take gb off mounts and prop and move back so engine can run disengaged from gb and if quiet you know gb issue

Agree lynall , I kept series 3 exhaust but mines a di, does that downpipe fit to the S3 manifold or the tdi manifold Some info here from 300, https://www.landyzone.co.uk/land-rover/exhaust-200tdi-series-3.298508/

almost Same one imperial one metric , nigh enough for pitwork as the saying goes

Just reading back through the posts , when it was running did you try it with fan belt removed to isolate any bearing probs on water pump / alternator , loose pulley wheels 🙁
