upgrade top end

[mattyboy5014]

i have a 2004 6.0psd, the motor is an 03 built, i have cab off and ready to order parts. there are so many pages about these and not 100% where to get everything. i want to do head studs, oil cooler, stc fitting upgrade, hpop, injectors and basically anything else i will need to make my truck last. already have egr delete and any input would be great

browns diesel has arp's the cheapest that I know of for $398.

Srmastertech has video documentary on oil cooler, STC, headgaskets, and injectors.
I STRONGLY reccommend watching all of them!!!!!

04 engines do not have the STC fitting BTW.


Update the fuel pressure regulator.

Cross off that STC fitting upgrade. You don't have that fitting on your 04.
I would recommend Ford head gaskets. The gaskets are not a weak design, it is the stock head bolts that were the problem.
Try Tousley Ford for all your Ford parts. They are a dealership out of Minnesota that sells Ford Factory parts at 10% over dealer cost. You won't find them anywhere any cheaper than that. 800-328-9552.
ARP head studs for $398, the cheapest I have ever seen.
If you want an upgraded HPOP, and never want to have an issue again in the future, and have a grand to drop for the pump, I would go with the Dieselsite Adrenaline HPOP. CLICK ME to check it out.
If you are rolling in the dough and never want to worry about your oil cooler, the Bulletproof Diesel oil cooling system is THE way to go. CLICK ME to check that out. You will need the cold weather kit if you ever see snowplows in the winter. The above link will show you the three different ways to buy the kit. Just pay attention to what year it is designed for, whether or not you want their egr cooler, and whether or not you want the cold weather kit.

thanks for the replies, would it be a good idea to replace the high pressure oil lines that feed the rail? i want to do everything right and not half a$$ it

[mattyboy5014]

and now im nervous, i am a mechanic and feel comfortable with this job, but not 100% familiar with everything on a 6.0 so i had brought it to a local dealership just to have it diagnosed by someone who did. thats when i decided to tear it down in my shop and just do everything i should, the dealership i had brought it to definently wasn't the most reputable and they only had it in the shop about 20 mins and said it was the stc fitting, perhaps he was in a rush and didn't check it out properly? i do have the 05 conversion, but the truck is in pieces and now i dont know what the problem is

[mattyboy5014]

i did plug into it with my scan tool and my icp was around 330 during cranking and i believe it needs a minimum of 500 to start? which i thought confirmed the high pressure oil leak

You could have leaking stand pipes or even the ball bearing in the side of the HPOP could have fallen out.

[mattyboy5014]

took off the hpop cover, the gear has some in and out play, aprox 1/8th inch, is that supposed to be tight?

[windrunner408]

Yes the gear on the HPOP should be tight as far as wiggling goes. You should be able to spin the pump by hand but not have any end wobble on the gear. I would say that you need a new pump. Just my opinion.
