series 60 is this normal??

sir u was absolutely correct,the egr failed along with the blue wires to the turbo booster were split,so i took it to stewart and stevenson to get repaired at a cost of 2300.00 dollars wow.anyway thanks for the reply

 

My friend had replaced his EGR, CAC, and Turbo and the sputtering has finally stopped for him. He's up to around 6.0-7.0 mpg (ungoverned truck, all 48).

My problem seems to have become more noticeable. But, I am starting to think it's a fuel delivery issue. Just recently in the past month I've been getting a black grainy oily crap on the fuel filter. I assume from a real bad tank of diesel. If I replace the filter, the truck runs like a champ for the first week or so. And then it starts building up the gunk (although the fuel level isn't rising much, if at all).

I'm starting to think I have a side issue of an injector(s) not firing properly, although I have no codes yet. But my MPG has dropped to 4.8-5.2.

 

Had a 2004 Columbia that was doing this. It went to Detroit Diesel...where they found an EGR gasket that needed replaced. Gaskets don't throw codes. And neither do cracked heads, as I found out the hard way.

It's what I detest about today's new-school "mechanics." They can't do anything unless the computer tells them. That's why I don't call them "mechanics" any more. They are computer readers and parts changers. That's all. A real mechanic can diagnose a problem and repair it without the computer telling him or her what to do.

 

Somebody peeing in the fuel tank???? I know diesel motors were designed to run on almost anything but sheesh!

 

I had same in my International Dump. Oil=fine, Fuel=good, fuel filter=not bad........ 1 think I've checked was bad, that was the TURBO.....
Turbo was overheating. When I shut of the engine for 1 minute or longer my truck was runing like new! (with over 1.8 mln miles on it, just construction used Dump, no more legal on the roads...1972)
So, check your Turbo, and remember, turbos are sensitive to heat!
Black smoke= not enough air to burn the fuel= deposit in the combastion chamber, on the pistons, valves, etc.....
Check Turbo for Boost management= how many PSI it gives to the engine at certine RPM and load. Not enough= black smoke, lose of power, low fuel economy, too much BOOST!!! your heathers can go thru the hood.......
