Hi guys! I’m watching this forum for quite a while now and it helped me out quite a few times. But now I’m puzzled and am not really sure what to do. So I’m in Spain right now and don’t have the right knowledge of the Spanish language to just go to a mechanic and see what he thinks. I first want to have an idea of what’s wrong.

So my 200tdi (disco engine) gives thick clouds of black smoke on the slightest acceleration. Now, it already happend twice on the same road (very hilly with a lot of bends) in one week time that there’s suddenly a big powerloss to the point I can’t go any further (in less than a minute). No warning lights on dash, engine temp alright according to gauge and boost pressure as always. According to the dipstick there’s no oil anymore, so I top-up about 1l and it’s already on max. Then the car starts again and gets rolling. Today I noticed an oil leak at the head gasket so I’m aware that will need to be fixed. But still I have the feeling that other things need to be fixed aswell to not get this problem again.

I’m having oil leaks since I have the car so I didn’t really cared about it because the oil level always stayed on point. I check the oil level everytime I start driving so I find it weird that there’s such a sudden loss of engine oil. Could this be because of the long climbing thus extra acceleration which leads to more smoking, which leads to higher temps in the engine although the gauge stays in the middle?

I have no loss of coolant. It doesn’t seem that it’s mixed with oil either.

Is it just a blown head gasket or is there more happening?

Cheers guys and enjoy new years eve!

a hose is internally delaminating and cutting air supply off

I'd never have thought of that

200tdi is a real pain to check oil level, my advcie is to check it when its been standing for hours preferably overnight.

Min to Max on the dipstick is one litre.

A 200 without some sort of oil sweat or oil leak is a pretty rare beast indeed.

I already checked the hose that goes to the turbo and that seemed fine from the inside. Are there more possible hoses?

The black smoke out the back, combined with the loss of power, will be due to you trying to burn fuel extremely inefficiently. Ie. Without oxygen, so you are blowing partially burned fuel out the back in the form of soot. That's why JM is suggesting a delaminates turbo hose. Take all hoses, from turbo to inlet manifold, completely off and check them thoroughly from both sides. Part of a hose may be flapping down, under pressure, and obstructing the air flow. Check how much oil is in the inlet manifold while you have the pipes off. Do you have a new air filter in it?

First of all, a happy new year and I wish you all a lot of adventures with your Landy this year!

So yesterday I checked all the hoses again and didn't seem to find anything unusual except for the air filter to turbo that did have some cracks on the outside from wear, but no crack seemed to go through to the inside. I will change that one to be sure. I didn't want to take the inlet manifold off because I don't have a new gasket for it atm. I checked the air filter and it was still pretty clean, it has been changed 2000 km's ago. Any other suggestions what it could be?

So you guys link the excessive oil usage to the black smoke? The weird thing is that it's alright for a couple of days of long driving where the oil level keeps steady and then suddenly disappears. Could it be that I need a new diesel pump because turning the smoke screw counter-clockwise doesn't really do anything?

Cheers!

have you mean messing with the injector pump adjustment,black smoke is unburnt fuel ie more fuel than theres enough air for it to fully burn

I didn't mean take inlet manifold off, just check it for oil, just in case your turbo is passing oil.
You didn't mention that you'd been playing with the FIP sounds like you've cocked that up. It's best left alone unless you know what you are doing. Hope you referenced the starting point.
