There seems to be something not quite right with my Cummins

[Allnew2Me]

I can't quite figure it out, but there seems to be something not quite right with my Cummins diesel engine. I've included a few pictures so that someone might be able to take a look and see what might be the matter.

It just seems that it is running on five cylinders, I don't know. It was fine up until this afternoon when I did a little fooling around with it. Anyone have any ideas?

I see you did not install the copper core plugs, that's yer first problem. Take them Brand X out and get the good stuff.

You Know Gary, it does seem like it is running on five, but heck if I can figure out why.

I don't get it, what do you mean?

And for another thing, an engine as clean as yours will NEVER run right! :-laf

Turbo Diesel, what will they think of next. Did you index the plugs?

Glow plugs! Must be Ferds new 6. 7!

It's pretty clear in the second pic that #3 and #4 are switched. Also, the 24 valve engines run too cool and will carbon up the valves without the proper layer of insulating road grime.

Thanks for the replies guys, but I still don't know what the heck is wrong. I guess I'll wait until I have to have it smogged and see if the smog guy can maybe help me out. I'm sure those guys know everything about diesels.

I think you might be right though, before I cleaned it it did run better and quieter also.

It seems as though you don't have a coil hooked up to your distributor

I think you might be on to something. Do you think that would explain the rough running?

You should leave all that on there when you go to have your truck smogged. I'd pay to see that!:-laf

Oh to be able to watch that test take place... ... ...

That exact thought just happened to cross my mind :-laf

Might be kind of fun!

 

[rbattelle]

That is hilarious. What are those plug wires sitting on? I mean, I'm not familiar enough with the 2nd gen valve cover to know - are there bolt heads in those locations?

I got lucky, the boots just happen to be a tight press fit on the bolts that hold the valve cover on. I've driven around for a week and they stay in place.

It took my neighbor with a Duramax about a minute before he figured it out, He asked, laughing, what they were for.

I'm going to leave them on when I have it smogged just to see if anyone notices.
