Power Puck "OUTTA HERE" !!!

[ACamilli]

My 06 dually with 34,000 miles just had all 6 injectors replaced and all 6 fuel lines. The high pressure fuel valve failed and excess pressure blew out 5 of 6 injectors. When they were removed fuel ran out of them.

I noticed over a few weeks time that it would idle a little rough sometimes, then would idle OK. Never any smoke and nothing ever out of the ordinary.

So after my check engine light comes on and DC says the high pressure fuel valve is failing... . I set up replacement of valve a week later. 5 days later i notice again rough idling from a mile from home. That last mile i notice that my fuel gauge is at 3/4 and it should be a F or just below. Where did the fuel go?

Now idling in garage i see oil in driveway... uh oh. I look underneath and black fluid is being sprayed down and out of my draft tube... uh oh again... . I shut off engine asap. I check oil dipstick, oil is up at least 12"! Got to be diesel in oil... . which it was.

I always ran power puck on 60hp for more mpg, not more power. Never tried it at the 90hp setting.

Now I have researched this power puck on the web and found out on the Cummins forums that the puck should not be turned on all the time because the fuel line pressure is way too high, it pegs fuel pressure gauges when turned on... . and blows injectors due to the extreme high pressures and blows out the high pressure fuel valve. All they described happened to me.

Just a word to the wise. Anybody want a power puck, make an offer.

Now i wonder how my engine parts are doing considering i thinned the engine oil with diesel for an unknown amount of time.

I love my Smarty sr!

It is well known that adding pressure kills injectors. Sorry you had to find out the hard way!

 

[clndesl]

what about the predator by dr performance. u guys think im going to have problems?

 

[Bob Wagner]

The Dr P box is also a pressure box

The Dr P box is also a pressure box

Bob is there a good thread that describles how much pressure is added in certain Smarty programs? How does it compare to other boxes?

 

[clndesl]

yea im aware its a pressure box but isnt pretty much every box adding pressure.

You know guys I never wanted to add power. the stock 325 is much more than enough. Heck my 1999's 215 hp was enough for me. ALL I wanted to do was gain mph, even if that meant losing some hp. All this being said I learned that mpg suffers because timing is retarded... thanks to Al Gore. I was told that this Power Puck advanced timing. Is there a device, easy to install, that only advances timing and will help mpg?

The answer is Rokktech

Acamilli:



Check out the Rokktech adjustable timing sensor. It gives you up to 2 degrees of advance. Many members are using this alone (me) or in conjunction with various boxes. I get 1 more MPG with it fully advanced. This has been in my truck for over 20k miles and two years.
