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 😀

Never measured the skirts but i would think you're more interested the the crown movement at/around tdc if you want to check for slappers (ooo-errr missus!!!)

Isn't that more high pitched? I've forgotten.. what does piston slap sound like? No it's not that is it because you'd hear it on every stroke?

Was small ends on pistons checked

The biggest difference is no combustion sending a shock down the piston/conrod

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...

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 🙁

if anything should be anti friction like teflon but not seen any online. (will have a google) i can see EW on them whats on other side

this is the worn rocker i replaced with new on mine but didn't make any real noise, maybe time to check the valve springs make sure they not broke and sit at correct height as in manual. guess youre quite sure you have adjusted each rocker to...

once you get started there's no stopping you! the rollers look good from what i can see , should all be highly polished with no flat spots, those tappet slides should be clean brass all over not covered in black deposits, did they move ok in the...

Will do. More tomorrow since I dont think I will have the time of day to fix it today. well isnt that true! Biggest ive had in a while xD No problems for the updates, I spent ages looking for similar knock questionaires and all found that theyre...

It's a puzzle for sure. Interesting! Thank you so much for letting us know as you go along

Oops thought it was oil pump, but try with oil pump skew gear and dizzy out first, On the rollers you can get flat spots but not as Loud as your knock more a tap But knock is twice as fast as a single valve operating unless it’s banging top and...

lift pump is out! i havent checked it with the drill with it in. That might be worth a shot to rule out that wasnt in the wrong way to begin with. I think head removal is imminent, i need to redo all the gaskets anyways at this point. Im glad I...

update: put the dizzy back in and took the timing chain off aswell as the rocker arm assembly. put a drill on the bolt of the timing wheel and “dampened” the pushrods with my arm. after getting up to a certain rpm; i hear the knock. i dont hear...

That’s a well thought out test, and you found the knock with dizzy in and lift pump , so keep going and remove ancillaries one at a time , ( lift pump lever on wrong side of cam poss) until sound stops, as you’re in so deep now not far from head...

update: the little pusher/insert slotted bit in the dizzy slot seems to make a really recognizable sound…

Or back off adjuster fully check pushrod in cup and slider not broke

From what i can see that bulkhead doesn't look bad. You can buy new door pillars and weld them in place

When a big end knocks, it's the bang pushing down on the piston that makes the noise, you wouldn't hear it during cranking

Mine used to leak from poor seal on sender unit when overfilled

I counted about 15 knocks in 5 seconds that’s 180 per minute Assume tickover speed about 720rpm, so cam speed is 360rpm Does it sound noiser with ear to air intake After rebuilding my 200di I had a regular clonk like that , turned out I stuffed a...

If it's in neutral, then can't be gearbox? Check valves first. I'd look at the dizzy, then the cam gear. Couldn't see from the video, is there oil coming through the rocker shaft?

Think my replacement drivers side has the cradle built in for bolting on , but the passenger side military tank had a cradle you could separate if keen to repair If it pours out when filling it could be over full, with gauge under reading ...
