Diesel Fuel Smell - Injector Pump ?
Hi all,
My 1978 300SD has recently started to smell like diesel when running. At the airport parking lot, I did a smell check and it smells like diesel towards the front of the engine and not the rear. When I got home, I looked it over - fuel lines, filters, return fuel lines and nothing looks or feels wet. I did notice that the front of my injector pump is wet however. I tried to see if something was leaking on it, but I couldn't tell. The injector pump itself is dry, except for the front end which faces the radiator. I have attached pictures with arrows pointing to wet diesel fuel on the pump. If it is the Injector Pump, I am out of my league on this one, I think. Please take a look at the pictures and give me your thoughts. I like to solve this one at a reasonable cost.... Thanks all!!! |

Bisric,
Are you sure that is Diesel fuel? It looks more like black engine oil to me. Clean the IP good with an engine cleaner and then see if you can find a fuel leak or wet spot. You should be able to tell it its fuel by the smell. P E H |

Yes there is oil on it - I admit the engine is dirty. However, it is diesel fuel. I verified it by touching and smelling. It just seems like a very weird place to leak. I submitted this post because I thought someone may have seen something similar. All my other fuel lines are dry....
Thanks! |

I would have to agree, and say you need to clean your engine, and do a real good job around the i.p. This is the only way you will be able to tell where the leak is coming from, and if it is diesel fuel for sure that is leaking. You should also look into getting some of your oil leaks fixed, if they are bad enough.

I know the oil leaks look bad - however she only goes through 1 to 1 1/2 quarters during a 3000 mile oil change interval. A lot of buildup from 25 years and 225000 miles. I don't have a place to clean it and don't trust anyone else to do it.
Any suggestions on how I should clean it up? |

All you need is some Simple Green and a garden hose. Make sure your engine is cool, and spray the Simple Green on and let it sit for a while, the hose it off. Repeat this process several times, and your engine will be very clean. Oh, and dumping a bucket of hot water over the engine too, will help rinse the oil off.

I use the local car wash for cleaning the engine. I do it with the engine WARM, not hot as in just got off the freeway hot. That seems to do a good job for me and your done in no time.
