I have a question to pose.

I have heard that some Aurora 5000 users are reporting coolant bubbles and hard hoses in their coolant system when running this charger hard. Since we are running the same ultimate boost values, what is the root cause?

Could it be the Aurora is off its map at 53 lbs?
Why are the EGT's high at the end of the 1/4 mile?
What is measured drive pressure in top gear at 53 lbs?


All those using the Aurora and experiencing these issues, have you tried re-tourqeing your studs at 250-300 miles after install?

I do know that CTD's can suffer like this is the Re-tourque is not performed after that mileage, and then checked again at 800 miles.

I am not suffering these issues, and would like to see you super single kick some @ss at the pulls in Muncie!

Go DMX Power!:ro)

;) ;) ;) I know it worked on one truck, and i'll see if thats the problem very shortly :ro) . It seems that if you did not replace the gaskets, but replaced one bolt- one stud pre time and re-used the original gasket the issue is not present. Once the head gasket was brand new, coolant issues arose.

My truck will be going under the knife very shortly(hopefully next weekend), to fix this nagging issue that had us stumped.

Now the million dollar question is, do i install new gaskets again, or do i just re-torq???? I've been driving with this issue for 3 months, trying to figure out what it could have been, although the issue only happens when i stack programs, but is fine when using the VA 200+ by itself. To me i would say the gaskets should be fine as everyday its fine, and it only occurs with stacking programs. If the gaskets were pooched i would think i would have the issue everyday, like when i did have pooched gaskets before the turbo went on, but its an unknown................

Here's my options

#1- Install new gaskets

Tear into the motor and install new gaskets and up the torq value a bit, and have a possibility that i have to tear into it again and re-torq after some driving. Total maximum times into the motor 2.

#2- Re-torq studs and don't touch gasket

Tear into the motor, but only re-torq the heads, and hope the gasket is fine. IF that doesn't work, do #1. Maximum times into the motor 3.

I have made my decision, but would like to see what others think would be there choice.

Other than this issue, which we weren't sure if it was just the normal bad luck of my truck(or me) the 5000 rocks :ro) Pulling this year should be very interesting.............on the street the truck is an animal, and almost has too much power for everyday, i said almost :D .....................i know i can turn the fuel down, but what fun would that be.

Ok (deep breath time)

The Cummins guys (running high boost) are checking the torque from initial on the 1st 250 miles, then at 500 miles, anf then every 1500 miles from that point... at least that is what I've been able to gather. Wether or not they are that anal about it remains to be seen. I do know a lot of the pullers who recheck the torque before every pull!

I sure hope this helps you guys... As much as I love my Cummins buddies, I DO NOT WANT to read a DMX puking a headgasket during a pull! (so yes i do have a selfish motive here... the mileage they would get out of it would be tremendous)

Good Luck to the PULLERS!:ro) :grd: :ro)

Oh, Jeremy, as a side note, try a retorque first (leave the gasket you have in there for now), get some cycles on the motor, then check at 250... see if it helps.

Ya, the only problem is, how many minutes does it take to re-torq a cummins...........compared how many days it takes to do ours -:t -:t

Jeremy, give us an Idea of how long that takes, please.

For a re-torq or the whole shubang?????

Hey, I never said it would be easy.
I'm only tryin to help a bit from my CTD experience (that and a 1.50 will get me a coffee anywhere in North America)

We get enough mileage out of your little "oopses" to hold us over for many months Pop Slippity. ):h Don't think we would ever have enough time to be reading about another persons problems. :lol:

Hey, Mr TwinMax #000000001 When are you gonna get YOUR but down here and PULL IT!!! :D

This comes from a guy who has nuked his injectors running a pressure box way too high (who warned him about that i wonder?:rolleyes: )
Then DESTROYS the NEW EDGE JammerII Turbo
Barely makes 500 HP with my patented Juicegrips(TM)
And then has the nerve to call me out now that he finally has a clutch to hold 497 HP?

Come on over... I will help you adjust that wastegate of yours! I have an extra roll of duct tape all ready to strap those pop cans down a little tighter. :lol:

Hey pop slippity, you mind staying on topic>?

When do you think the retorque should be done on the popcans?

:blahblah: :blahblah: :blahblah: :blahblah:

What?

Hey pop slippity, you mind staying on topic>?

When do you think the retorque should be done on the popcans?

It all depends on how much pressure you are running. In the race truck we see 100PSI at the intake horn every run. We retorque every other time to the track. Sometimes more. (depends on how many I-5 test and tunes we partake in :D ) We found that if we kept up on the retorques we cut the number of head gasket replacements in half.

Do you guys have head studs or bolts? Do you need O-rings / fire rings?

I would think that O-ringing the head would help a ton..I just hope that a receiver ring wouldn't have to be cut in the block as well. :eek: :(
Also, would a copper head gasket work better for the all-out performance trucks than the original gasket? :idea:

Studs..................fire ringing/o-ringing might be the next step in the quest. Max that i've seen is 53lbs

copper gaskets and o-rings will NOT work together without receiver grooves.

That I'm going to disagree with. My 02 CTD has dual o-rings and a copper gasket without receiver grooves. It's been to 75psi pushing 300 times without leaking combustion.

fpc is correct. Squish don't hold.


...Heartbeat, can you give us both times?

Well i can give you new gasket times this time as thats the way we are going, but if we have to re-torq them-:t , i'll be sure to let you know. It sure as hell isn't gonna be as quick as Eric gets the job done, but we'll :grd:

Check these out I just put them on my supercharged NOS malibu. :ro)
No need for O-rings with these and i believe they will custom make them too.

I've had good luck with tractor motors as well with copper headgaskets and oringed heads without receiver grooves. This seems to be a debate that will go on forever between engine builders and machinists...

Idaho CTD...

Do you have twins on the 04.5?
Stock gaskets?
Are you at the same Duramax 53psi?

Anyone run the 5000 with stock bolts without any head lifting problems?

Yes
Yes with studs and it holds 65psi
Nope dont have a Dmax

Not all Aurora 5000 equipped Duramax trucks are having coolant bubble issues, just a couple that had/have leaking injector cups. I know of a few Duramax trucks with the stock turbo that had the same symptoms. Resealing the injector cups took care of it.

This is the same setup as our race truck. O-ring on the block, slightly larger O-ring on the head, and a thick copper head gasket between. This causes the gasket to be a ~ shape arround the cylinder.

thats good info. I didn't know dual o rings would work without receivers. I'm gonna try it on my Oldsmobile race motor. Thats how i found out single o rings and copper don't mix without grooves. I did learn that the o rings were perfectly centered with the fire rings on a fel pro marine gasket and they hold 13.8 to 1...if you think about it, the fire ring curling around a single ring is kinda like the s shaped interlock that was mentioned earlier... kinda, sorta, ok not really but dual rings make sense.

I've retorqued a total of 3x since I installed my ARP studds/Don M o ringed head last June.Ive since got over 16,000 miles on the truck,not to mention over 300 hrs of snow plowing (which only registers about 1000 of those miles.I just hit 65psi today testing my new fuel system, I might retorque in a few weeks,the ARP studds really have helped a lot when it comes to clamping power.(I still have the NX N20 setup),and i may put it back on the truck,I SHOULD leave it alone as is,it runs great,but what fun would that be.:grd:

A little help from the CTD crowd and their experiences will go a long way!
We won't have as many 'blowing pains' that way

Thanks.

See guys, even the woolie bullies want to help the DMX!
(Bet they don't do that around the Ford camp!):D

Would Juice know what a CP3 pump was, even if you hit him in the head with it? .......Wait a minute, I'll try. We'll see what happens.

Is that angainst the :rules: ?

Any "new" CP3 folks out there?











.......Mods, this also had "null" in the box.

i run copper head gaskets on my 14 to 1 406. i have the block oringed with no receiver grooves in the head. the wire i run is copper though, not stainless. i have pelted this engine with a 300 shot of nitrous over and over and never had a problem. wil
