Dpucket, I don't think I need to test my pump now. Last evening the fellow from Red Oak Diesel inc., returned my call and we had a long conversation about the heat in the egt and his injectors. He said that these engines don't respond well to timing advance much above .100 inchs above the original mark. Sooooooooo I backed the timing off to .100 inches advance and gave it a test run. Temps were higher at the bottom and the same at the top. I made two more adjustments and the temps came down a little, smoke dropped a little , power dropped a little.
This morning I cranked her up to take me to work and it started on five cylinders, shook like a dog trying to pass a huckle berry and smoked like a freight train. Then after about ten to fifteen seconds the sixth cylinder picked up and it drove fine. It sounds like it is time to throw an injector pump at it. I hope it ain't so.
Comments??????????

 

I thought the VE was a rotary pump and supplied fuel to ALL the injectors, opposed to the inline pumps where there is a plunger for each injector. Is it possible that #6 had air in the line?

Just please be careful #6 seems to get the hottest out of all the cylinders. I hope you find your troubles and it turns out to be an cheap/ easy fix.

Good Luck,
Michael

 

92DIESEL, you are right- it has one plunger for all 6 cyllinders, and it pumps in and out, with the spill port rotating to each cylinder. BUT, there are delivery valves that can go bad or stick, causing a rough idle and bad smoke.

It sounds like injector pump time. If you'd like an alternative to Red Oak Diesel, call Northeast Diesel in Jackson MO. I've had 2 of my own trucks' pumps redone there, along with my mom's, and have been happy with all of them. Just make sure you request a spring kit in addition to the rebuild. I think they will ship. They will flow whatever amount of fuel you ask for.

Good to know, thank you for clarifying that for me

Michael

 

Duh, I don't know which cylinder it was on, just that five of the six were working. Sorry about the confusion. When I crankedit up at work this after noon, life was normal again.

 

Red Oak Diesel has been doing just fine. I'm gonna ride this one out for a while and see what developes.

 

More likely you have an air leak on the supply side. Check that thoroughly before you decide it's the pump.

 

They sort of lose credibility with me when they say these engines don't respond well to timing advance. With your timing set where it was at before, did the engine ever start and run like it did this morning?

 

What he really said was that when you run the timing up past 1/8 inch the benefits of the added timing is diminished and is actully causing the engine to fight itself. I had it all the way to the head when I first put in the High Performance injectors and then ran it back to about 1/4 inch. Now that I have these new injectors I started at about 5/32 and dropped back in small steps to 3/32. She runs smooth and the egt's are basically the same so, I am going to bump it back up to 1/8. I'm getting frustrated trying to tame the egt's. Right now everything is suspect. These injectors are supposed to run more economically and produce good power with minimal smoke. With the pump maxxed out and running the Bully Dog pin should I be having this much heat with a Stage IV H1C?

 

It seems kinda hot to me, but you've done the simple stuff. I think you should put on a valet switch or turn the pump down until you can do more air. It will make towing less frustrating if you can use all the power.

 

---OR, you could swap your injectors for my stock ones

I've finally driven Dave's truck and its still a puller with the valet switch on, at least 2/3 more power than mine... I would suggest trying that for not.

Good Luck,
Michael

 

Please pardon the hi-jack.

When pulling big heavy cattle-trailers, my eyes are constantly glued to the pyro.

I have to constantly back off the throttle, to keep the pyro from breaking the needle.

Will this "valet switch" allow me to pour on the coal, without seeing shiny flecks of aluminum sprinkling the sides of the trailer??

Thanks.

 

The valet switch will not let you have any AFC fueling (you know, like when your boost hits a certain psi you feel a little power pushing you back into the seat), so you do lose some power BUT you may also drop the temps considerably (sp)... I hope this helps, if not I'm sure someone else can explain it better than I.

Give that man a cookie- he got it right twice in one thread . The valet switch cuts the full power capability of the truck. It's also the same as disconnecting yout AFC hose, which may be easier when you hook up to the cattle trailer. Beware, though, it may drive like a stock truck, though with stock EGT.

But, when pulling the cattle trailer, how big a trailer, how much boost/ EGT are you seeing? A turbo upgrade may be in your future....

WOW- Thanks, I feel special now
