First start up...... not great, please advice

t0m1980 · Oct 16, 2018

So after far too long I got round to starting my engine up, it turned over and with a big plume of black smoke it fired up.

It was short lived though due to the revs not stopping, a bit of research on here and I came across “200tdi revving it’s nuts off on start up”"......... so I followed the advice but I came across what looked like oil as soon as I took the cover off the pump, can that be right? And if so how?? The diaphragm looked perished ever so slightly and when I liffted that up I couldn’t see anything move, when when moving the throttle.

I’ve decided to invest in a new pump (reconditioned that is) but just wondered what your thoughts were as to what’s causing the black stuff, should I be worried? I’m hoping it’s nothing but I would have thought it should just be clear diesel in there.

Also to ask if there would be anything else that may cause the engine to rev up like that? I wound the throttle all the way off, so it’s not that, and to be fair it’s just a bare engine sitting in a chassis...not even a cable to the throttle.

Many thanks
Tom

There should be nothing in there, but black oil maybe points to a turbo failure in the past that has contaminated the system, the oil wont hurt anything, so no worries on that score.
The rubber only gets pressed down by the boost pressure that the turbo makes and shouldnt effect the idle revs at all and if the rubber is split you would be down on power under load, Ive never personally seen one split.
As for the revs if you arent sure and can afford to get the pump checked/rebuilt then thats the way to go.

Peter at rochester city diesel is quite good, I think a lot of people have used diesel bob up north somewhere and hes meant to be good and sensibley priced
The guys up at detling are meant to be very expensive kent diesels I think?

Ah thank you, that’s reassuring I was holding off just in case it was something serious... so sounds like a trip to Bobs shop online, to be fair that’s where I was looking to go, as you say loads of people seem happy with him.

Also time to invest in a PM029 I guess lol.

Once again many thanks!!

I had to google pm029, the cheap timing pin kits come with the tool you need, well I think its the kiddy? have a look on ebay etc.

This is the one Ive got, search first as theres bound to be cheaper.

Is the turbo to manifold intake hose full of oil?

Much appreciated

Not sure, can’t say I have checked to be honest (not a competent mechanic, just winging a project with all the help from you guys).

Say if it is, on a scale of 1 to 10 (one being shocking) how bad are we talking?

Just about every small turbo diesel that has its engine breather pipe routed into the engine air intake system will have oil residue is all of the intake pipework.
So if you take off the lowest pipe and a drip or two comes out dont worry , if on the other hand you get a puddle either your engine is knackered or thr turbo is passing oil.

My series 2 with 200tdi is well worn, so worn the engine breathes like puffing billy when its been worked hard and I have routed the engine breather pipe to atmosphere and the intake pipework is bone dry.
The 90 200tdi used to mess up the oil filter, so again I routed it to atmosphere and weirdly now its breathing to fresh air it doesnt make any mess at all!

On my wifes Audi if you pop off the intake pipe to the turbo there is always half a teaspoon of oil sitting there, this is here third car wth the same size engine and they all have the same oil sititng there.

If the turbo bearings have failed oil leaking into the air intake can cause the engine to runaway and self destruct using the oil as fuel.

Hi guys sorry for the late reply, an operation forced an unwanted break, and by that I mean... I had an operation and she capitalised on the fact I was off work and took me away.

So reading reply’s I’m now left a bit worried my engine or turbo (or both) is on its way out...... which is handy as I’ve just bought a reconditioned fuel pump.......

t0m1980 · Nov 5, 2018

Also whilst I think of it, the guy who reconditioned the pump said it looked like it had acid in it! WTF is that about??

Second hand engine, so no known history.... he did say though it would have not hurt the engine what ever it was, I have new pipes to and from, just the old pipes to the injectors.

He has reconditioned the injectors as well.... so do I stick it all back together and hope for the best?

run the engine with the turbo to intercooler hose removed at the turbo and with the boost pipe disconnected

t0m1980 · Nov 5, 2018

Ok I’ll give this a try tomorrow, please excuse my ignorance but what will this prove? And what should I expect?

t0m1980 · Nov 6, 2018

I’ll let you know the outcome when I manage to refit my pump, I’ve managed to line it up in order to get the pin in, however I now need to do the timing again, which all though this should be a straightforward job, one of the wading plugs decided it’s happy in its current position and does not want to move out.
My friend is bringing his welder down Thursday to weld a new nut on, and hopefully I can then set the timing up, and start again.
