Evening, my old ‘85 300TD OM603 flung up a bit of a problem this evening and wondered if the group could help. About 6 months back I renewed the rad, top and bottom hoses, water pump and thermostat. I have not renewed that small piece of rubber pipe running off the thermostat housing because I...

So I've gone ahead today and tried to remove the Modulator. Just to give background this gearbox was rebuilt by a good firm in Fakenham, Norfolk a while back and hadn't been used since because the Neutral Safety was broken. So with various forms of 5mm Allen key/socket I've attempted to undo...

@John757 thank you I‘ve just seen this, all good info. I hooked up my smoke tester again today as I was convinced there must still be a leak somewhere. And what do you know, it was underneath the car, coming from the (red) gearbox modulator. So I isolated that with a golf tee and went out on a...

**update** Finally had a day to sort this, or at least try. I purchased leads, plugs, cap and rotor. Changed cap and rotor first, no difference. Changed leads, no difference. Changed plugs, set to 35 thou… bingo!!! Some oil inside cap and plugs were battered. I’ll monitor this… thanks...

Ahhh ok I’ve never done that. Should I remove it? I’m not intending to run veg 🙂 Thanks Dot

Evening, I’m after a few bits for my ’85 300TD if anyone can help please? Front and rear mudflaps - with logo Fuel sender unit (touring/estate version) Roof rack Ta! Dot

Noooo, Niet, nada, rien! :-)

Thanks Optimus - I don’t have an Economy gauge - to be fair she ain’t that thirsty. I’ll be looking at this at the weekend. Dot

It’s a Mercedes 120 degrees cap. @audiavant - I did flush through from top and bottom, in total I got about 8 litres out, and back in again! Dot

Thanks Optimus that's really good info to start from. Question though - my locks are working fine, so would that lead me to think the rest of the vacuum system is also ok, or should I begin checking it out? I've got a smoke tester now, and am itching to use it :-) Strange thing when trundling...

Morning, I'm bringing up what seems at first sight as a subjective issue of running temperature on a W123 diesel. Looking around the US forums there seems to be varying views on running anywhere from under 80 degrees to just over 100. I'm obviously still acquainting myself with my 300TD, with...

Thanks Chipchop - she does warm up quickly, running at about 90/95 C. I’m looking into this too and think this should be cooler. I am thinking about checking the thermostat. Dot

Evening all, in addition to the 123 I’ve recently got hold of a 1991 300TE. It’s been pretty well looked after, but I have taken it on with a couple of issues. I’ve decided to post here instead of the electrical section, forgive me if that‘s incorrect. M103 engine I think. When I fire her up...

Evening all, I’m currently still getting to know my ’85 300TD, and she’s beginning to run well. In doing this I want to begin cleaning components in the engine bay and the fuel pipe work to give a nicer appearance. The injector pipes covered with orange insulation tape which I began to remove...

Ta, but aren’t they a special size? I had this issue with my 124 a few years back. Never found any that fit. Strangely with a 124 I just picked up one of the Pioneer speakers had shorted out. The guy in the shop (that had been there for years I may add) scratched his head, went to a store at...

Ahoy all, I’ve fitted a rather nice Blaupunkt MR21 Hamburg stereo into my W123, and I’m getting awful sound from the speakers, no real volume either. I’ve had a look at the speakers and they’re Blaupunkt too, but can anyone suggest any alternatives? I’ve also got two speakers in the rear at the...

Smoke tests revealed one leak, one of the vacuum pipes to the ignition barrel had come off. I then ran her up and down the road and upon my return the central locking now functioned fine, but the engine would still not shut down, so I turned to the shut off valve. When I shut down now the valve...

If that’s this week then bring it on! FInally there with electrics, I’ll do a detailed post later. Got a smoke tester to find that last leak on the vacuum system. The engine is trying to shut off (much much better than it was, so it must be almost sorted). Got Mot prep to do for tomorrow...

Just bought one… But a q - is the green valve pictured here a one way thing as I’m getting blow through both ways? And what’s the bottom right angled line with the green stripes for - this is open ended over in the other side of the engine bay??

Aye - find it awkward to follow that’s all 🙄🙂
