So what is exactly Black Death? I recently read about it me now slightly worried.

I recently replaced the o-rings and crush washers for the deliver valves since I was leaking fuel and could see the drip and smell the fumes in cabin.

Now there is no more fuel leak but I can still smell the fuel. I do remember when taking of the cover I could see fuel in the head. The smell is very strong towards the back near the cabin.

Is there anything I should look out for or other symptoms I should be aware of? And maybe some advice in fixing the fumes which gets very strong at times.

I'm driving a 95 e300 om606

Black death is a description of having algae, or more accurately, fungus in the diesel fuel. Creates a black sludge that plugs filters, lines and such. Pain in the tail to get rid of. Black death has nothing to do with fumes, so the rest of your post is unrelated to it.

As for smelling fuel, any leaks or drippage can linger odors for a very very long time. Might be useful to wash out under the bonnet and see if it returns. A clean engine bay will make it easier to detect the source of any leaks.

There is also a Term called Black Death that concernis the Air Conditioning; but, I don't remember the details.

Then again it ravaged europe at one time.

That one I believe is mold growing in the ductwork or on the evaporator due to poor drainage of condensed water.

I thought it was the compressor chewed up and the garbage distributed through the air conditioning system.

Apparently you're right:

What is Black Death?

Lots of different topics here hah, here's a picture to what I'm referring too aka CDI Black Death also

From Sprinter-rv.com


“Black Death” – The most serious possible problem is injector leakage, a.k.a the “black death”. The fuel injector hold-down bolts may get loose or the seals erode, and the injector seals may begin to leak, producing black goo (“coking”) in the injector compartment on top of the cylinder head. Despite the name, this problem does not mean the “death” of the Sprinter, but it can be a major repair, depending on how far it has progressed. To check for this, remove the 5mm Allen bolts securing the plastic valve cover and inspect the injector compartment for leaks.

When inspecting for leaks does the car need to be running? Always wondered what the car would sound like without the intake that crosses over the head.

Anyways, what would I look for when its leaking?

This is the one I was speaking of but the Article I read was somewhat different.

Took a video today, I wonder if there's too much fuel in the head at #6 that's causing the fumes to come into the cabin also. Otherwise it looks pretty clean at the moment.

UM, I think you have a major problem. What is that liquid around your injectors? I have no familiarity with your engine, but that looks really wrong to me. Someone else needs to chime in here, but if it were me, I would not drive a car with such a substantial fuel leak.
