Black diesel smoke on start up. Why..?

My 200TDi is the same, I will watch the following posts closely...

Black smoke is unburned diesel that has been fired in during start up Nothing at all to worry about

totally normal they all do, only worry if the smoke is white ( water leak, head gasket ) or bluish ( engine oil, rings )

although older less advanced diesels can white smoke for a few minutes after start up while they warm up. When I was in the TA it was always interesting when we started the Bedford MJs up. If we hadn't been discovered, we were then!

Phew. Sounds as if I can relax! Had visions of something very expensive...

Cheers - off to play in the mud in the Forest of Dean now, first time. Here we go, here we go, here we go, etc

Get ready for your next scare.

Do you hear any squeaking from the water pump area??

Sorry! Couldn't help it.

Mine is back, by the way.

I get that with my petrol engine :)

Mine squeaks but only when it rains ????

Lots on Google about this, also suggested "cures". It is in fact the "fan" belt and the best explanation I had was from the tech department of a belt manufacturer. He said it was due to glaze on the tension pulley -- similar to the effect when you draw your finger down a clean windscreen. Apparently, they all do it (300TDi's) but it's nothing to worry about. Quite fun reading the suggested "cures" though!

Derry

Not neccessarily. The squeak from mine had been getting progressively worse, even with deglazing the tensioner, using belt dressing etc. etc. Finally I gave in and bought a new tensioner assembly - and I now have silence. Well, apart from the engine noise and the strange squeak that only happens when I turn left, that is...

The old tensioner has in the order of 2-3mm slop in the pulley.

I rebuilt my tensioner with a new bearing, a bit cheaper than the replacing the whole thing.

Still squeaks a bit on damp mornings or after driving through a ford though.

I've given up trying to shut it up now.

I get a great big cloud of white smoke from my petrol engine (2.25)

does that mean mine is racist or its something to do with the valves?

Me too. I think it's called "auditory fatigue" or something like that.

But I didn't mean to suggest that glazed tensioner was the only known cause of squeaks in a 300Tdi. Perish the thought!

Derry

Well, it wouldn't be any fun if it was that easy, would it?

So far I've got the left-hand-downabit squeak, the occasional squeak from (I think) a door, and the irritating squeak from the plywood in the back being screwed down too tight. Of course, if it isn't tight enough, the ply rattles instead...

I'll probably rebuild the tensioner assembly at some point, but I needed a quick sanity fix. This had hit the point of a squealing howl on every journey, which was getting a bit much.

Here's another possibility for you.

Opened up the bonnet of the 200Tdi the other day and some dog biscuits dropped out of the sound proofing onto the engine.

Strange, I thought, as I gave it a bang. More dog biscuits.... then a mouse.

So maybe it wasn't the belt that was squeaking after all??

Derry

This is one of the more unusual stories I've heard on afl. It begs the question, how did you get dog biscuits in your engine? I'm anxious to know.

Mice are known horders. The 200Tdi was lying idle awaiting repairs. The mice clearly took the biscuits "home" for the winter. Now, I'll agree, it was some feat to remove the biscuits to the sound proofing above the engine! But it did happen and I wasn't too surprised. Mice seem rather fond of moving into vehicles. The biscuits, by the way, are rather small -- about

Derry

OK, I've checked for dog biscuits, mice and soundproofing - nope, none of those present...

I once found that mice had carefully stashed a sizable amount of poisoned grain in my bed (under the bottom sheet) whilst I'd been away for a while. Returning the favour, perhaps?
