I’ve had an annoying knock on my engine for months, and I can’t track it down However it’s been stood for a month and when I started it, it was really quite, ran it for an hour or so and around 10 miles, all good. Today started it again and back to the knocking any ideas please?

Hi All, I had my engine stethoscope out today and put it on the top of the injector (No1) , the noise was extreme, sounded like metal on metal, tried it on the block and was ok, tried other injectors and they were very noisy but more ‘dull’ sounding. I released the fuel pipe nut on No1 to bleed...

I know what you mean, but it is definitely more quiet when I start it up (after a hour or so) then when I stopped it (when it would have been hotter), I was thinking maybe something was releasing after prolonged heat, I know it seems weird but it happens all the time!

Not long since, one was out but generally ok

Here’s an odd one - 300tdi. I’ve noticed before that when I run the Landy the engine can be a bit noisy, but if it’s been run for a while then left an hour or so, it seems much quieter! Tried it again today, 20min run, left it for 11/2 hours, and a lot quieter when I started it again! Any...

Voltage

Tried that, no joy

Hiya, I know the BC gauge is a simple thing, however I had it out of the dash recently and now the needle goes right up to max! It’s wired to live and earth as before, just seems a coincidence that it now doesn’t work (was ok before I took it out) any ideas? Alternator checked and charging...

Doh, sorry, 300TDI Defender

Hiya, Easy one I hope, the governor pin which acts against the boost pin was quite stiff (wouldn't move using throttle), I stripped it down and eased it by moving it back and forth with some WD40 in and it's now a lot easier to move. Question is, how easy should it move? I can push it back and...

The sensor is connected in the top hose, can't see any extra switches anywhere. It doesn't look like there are is any way to adjust anything on the sensor either, not sure what temp its supposed to kick in, but the gauge was really high!

Hiya, I have an electric fan fitted to my 300 TDI, during the colder months I had my Radiator cover fitted and on a couple of occasions the temp gauge was really high, however the electric fan didn't kick in, what's the best way of checking if it's working ok? Steve

Thanks everyone, cambelts fairly new and I’ve checked/reset tappets, so I’ll give her an oil change with some good 10/40

I've always moaned about my 300TDI Defender having a noisy engine (clack, clack,clacking), even though most people think it's ok! (I've had 200's and 300's previously) However, twice in a row it has been normal noisy in the morning on a 12 mile run (6mile, 1 hour stop, 6mile), but then when I've...

Just changed my Lt77 and transfer box and I’m left with this, any ideas?

Just found out my selector housing is in really poor condition, anyone out there got a spare one I can buy - LT77 box

Now had both props off, separately, and tested in diff lock, whine still there! T Box was about 500ml short of oil, now topped up, gbox oil ok as are both diffs, whining still there on decelerating! Any thoughts about how I can track down the source?

Right, got the front drive shaft off, not run it yet, ran out of time, There’s about 25mm diff flange rotation at the bolt hole diameter, sounds very ‘clunky’, Is that normal

Hi James, thanks for the prompt response. Not sure at all, sounds like it’s coming from box area, but I guess the noise travels. I will try and get the front prop off first and give it a spin with Diff lock on. If I could upload the sound file, you would hear that the sound sort of bounces...

Hi All, Seen a couple of old posts on here relating to whining, mine is a LT77 fitted to a 300TDI on a 90 Defender, it only happens when I take the foot off the gas i.e. approach to a roundabout/giveway, it's not a deafening sound, but loud enough and very annoying. I've taken a sound recording...
