"04.5 KA-POW (Now What)

[DPKetchum]

If I remember reading correctly one of the differances between H. O. and S. O. WAS the oil nozzels in the pistons as well as exhaust manifold and flwheel. Other wise just as beefy,same crank,rods,head etc. Pistons,manifold,flywheel were some of the things listed as differant from H. O. & S. O.

 

[DPelletier]

In the 2nd gen trucks the HO had some physical characteristics that were different than the SO's. The HPCR engines are all the same ('03-'04), with only software changes to differentiate between the SO and HO.

This mentions the 1991 Cummins got "new and improved piston cooling nozzles" so I would surmise they've been utilized all along: http://dodgeram.org/tech/dsl/Facts/epa_changes.htm

Seems to me the "lesson learned" is to have the pyro pre-turbo. Better yet; have the pyro in an ATS manifold with the sensor nearest to #5 piston. I put mine in at the intersection of #5 and #6 to get the worst case reading.



I see 1550s on rare occassion at WOT with all my power upgrades; but only for short bursts (a few seconds). I don't think it hurts anything unless you sustain it -- I absolutely wouldn't pull a hill with the trailer at that temp!!! Also note I'm reading the worst case scenario; between #5 and #6 piston.



Bottom Line? Measue the temp pre turbo; bias the reading to #5 and #6. I really think ceaman would have noticed a dramatically hotter reading and known something was wrong. That's not caeman's fault; the dealer was giving him incorrent info IMO.



... ceaman; I'm surprised they're not getting you a new engine. That #5 looks pretty scored.

 

[DPKetchum]

Well what I READ about the differance in H. O. and S. O. manifolds/flywheel and pistons was for 03. There was a differance between S. O. and H. O. More then software. When I was looking to buy a 03 the differances were advertised by D. C. Other wise a Mopar PCM change would make S. O. s a H. O. and theres more to it then that. I could be wrong but I am sure I remember reading the differacnce in from D. C. sales brochures.

Just to clarify, in my post I meant I thought the nozzles themselves in the HO engine were "beefier", not any other parts of the engine. Rereading it seems confusing. Sorry about that...

My motor is an SO (good'ol California). I was under the impression it's a few pieces and the computer. Why can't I switch the ECM for an HO? Just doing that is worth 40hp right? All the internal pieces aren't SO stuff anymore.

Big MAK,



I find your observation about the hottest exhaust gas temperature being between the #5 & #6 cylinders to be very enlightening and I really like your advice about measuring EGT at this hottest point on the exhaust manifold. Would you please post pictures showing where/how you installed your pyrometer on the exhaust manifold. Did you have any problems and/or do you have any special advice on the install?

 

[ceaman]

it has been over two weeks... . and still no parts..... still no ETA on parts...

 

[Big MAK]

Here's a bad angle; I'll try to get a top view next time I'm at home in daylight. This is from the "PDR Comp Twins" album in my gallery. The pyro is at the top right of the pic; the wire loomed line running down in front of the heater tube (which has been relocated to above the manifold due to the twins). It was in about the same place when I had the 2pc ATS in; prior to the twins install:

Called DC customer service and they will have a motor shipped out today!

 

[ceaman]

I called the DC customer service number and they shipped the motor to the dealer that day (wednesday 12/15). I spoke with the dealer on Friday (12/17) and they had received the long block to replace the motor. They had told me that the truck should be ready to be picked up Tuesday (12/21). It wasn't ready, so I called today at Noon and they said it should be ready tomorrow. . I called at 5 pm today and they informed me it would be the end of next week.



I called customer service again tonight and informed them of my unhappiness. They contacted the dealer and the dealer stated that they had to order a new starter because the one off of the original motor wouldn't fit, so they were ordering a new one. Then DC customer service said that apparently the motor they are going to install isn't a 2004 engine, it seems to be an older model, and that parts have had to be ordered to fit the replacement engine... . Then the dealer told the customer service that they supplied me with a rental car, but they didn't tell them that I was the one who had to pay for it!



Any suggestions... Am I wrong to think that if they are replacing the engine that it should be the correct.

What a comedy of errors. I wish I could say it's atypical. Why would DC change the starter? If I were you, I'd call another dealer and get a part number for a starter for a 2003, 2004, and 2005 truck and see if they're all the same.



You certainly have every right to be very angry.

Here is where I put mine... I was told that is where it gets the hottest.

How in the world will you (or any dealer) order parts in the future if you don't know the genesis of this engine, including the modification and service bulletin status? I think I would stop what's going on and insist on an EXACT replacement and written proof that it is an exact replacement. What they appear to be doing might plague you for as long as you own the truck..... or so it seem to me.

[ceaman]

I will put a stop to it if is in fact is an incorrect engine... . and i am in total agreement about replacing anything later... .



How can they not place the correct year block in under warranty?

 

[Briman]

Ceman, do you use this truck for your lively hood? If you do, is there not a law that would prompt DC to overnight any needed parts to you to facilitate getting you back on the road? Perhaps that’s why they responded so quick to your first call to customer service.



Good luck dude.

 

[ceaman]

I do use it as my only source of income. I am unsure of any laws... but i think its getting about time to find out!

 

[Briman]

How about it DC, do you think you can get this guy the correct long block tomorrow??? If I understand it correctly you need to do everything possible to get this business man back on the road as soon as possible, including air freight. Ceaman, call your area rep ASAP.

 

[CumminsBu]

Ceaman I thought you said you liked the 555 over the 600 in another thread.
