Injectors are still at F1 but April sent me a msg. Tonight saying Don should have them checked out and done by Friday.. I guess I'll have them back by late next week...

I hate waiting but I just have to be patient.

If the injectors were'nt the problem, im gonna be stumped and prob. have to pull the head to check the HG, seats, valves, etc.

I'll keep it posted up once they are back. Thanks for checkin tho!!!
 
I wouldn't rely on a comp. test. Mine tested good and when the head got pulled we found the cylinders were scored. Then I got a reman long block from chry. and it started missing on a cylinder. It also comp. tested good with a bad head gasket.

I would think that he would have seen scored walls with the borescope..

Bore scope wasn't the best quality in the world....kinda milky but I was able to tell the pistons didn't seem melted though...

If all else fails, I'll be pulling the head!!!:bang
 
Good luck and always keep an open mind about the little things....sometimes they will drive you nuts, as unimportant as it seems could make a big difference...

Thanks man!! and your right...The little things can add up big time!!

At least I'm gaining more knowledge about these things and how the act and what it takes for repair/diagnose/etc. .......

I'd just rather be driving it though!!!!! LOL:bang

All I was saying is I would not rely on a compression test. The rebuilt I got from Chrysler showed less deviation than his and I had problems.
 
Hey David, sorry to hear bout the problems. I thought I read awhile back that you had tightened your wastegate actuator all the way down to help increase spoolup. Did you do very many full power runs like that? The increased drive pressure wouldve been considerably higher than your peak boost of 62-64psi...possibly causing a head gasket issue?

How was your wastegate setup last time u dynoed? Your 800hp dyno was with the screwed up wastegate pucks, right? Is it possible the difference in drive pressure between the two dynos could have a 100hp effect?

I've got a drive pressure kit coming from LazarSmith sometime this week, I'm curious to see where my DP is at. I dynoed 773 last week with my gate set at 1.5 turns out. I think there's a good amount of power I'm still missing by not having it tuned perfectly.

And I know it's Bern mentioned before, but I'll have to agree that these warmer temps really effect spoolup and smoke for me. Once my motor gets heat soaked, smoke and spoolup is way different. On my to do kist is a heat shield box setup for my intake.

Good luck and let us know as soon as you hear from Don!

WOW!!!! 773 is Awesome man!!!!!
:Cheer:

Btw, the most I actually ever dyno'd was 766...That was Right after it was built and just before I had my first HG issue....Replaced the HG and then went to the track.....It was my track times / trap speed / weight and the calculator that I determined that my HP was closer to 800....I never dyno'd that high...

Well, I only tightened the WG actuator up during this last dyno where I did 693.....But back when I was having issues with spool and Power loss problems just after my 11.47@118 runs, My WG setup was NOT ran all the way in...It was set at about a 1/4 inch of travel like you said to set it.....

I've just had a series of problems ALL at once since my fastest runs:
WG cover plate warped and was leaking
WG arm bent and pucks were sticking
Broke an Input shaft
Starting getting even more ticking/rattle that I think may be injector related
Htt did the initial fix on my SS housing but still have spool and heavier smoke issues.....

I know the heat has to make a difference but I just can't see it causing all this at the same time....

I'm just hoping that it was in the injector(s).....If they come back clean, I'll be pulling the head to make sure the HG is OK.....I also need to make sure I don't have something going on with the cam/valves/seats.....I haven't meassured lift yet either...I need to make sure I don't have any other exhaust leaks too...

Oh well.....One thing at a time I guess.........I also need to check my intercooler for small leaks...It is a stock one off a wrecked 06..It has a slight bow to it but im pretty dang sure it wasn't hurt when we installed it...It was on there when I did my 11.50's, so I don't think its a problem unless it happened recently....

So much to check on these things!!!!

The heat makes a big difference in my truck. I can honestly tell a difference from driving in the morning and mid day when its peak.

I constantly check my WG and cover, its always good to go. I got lucky, nice thick cover.

Man i bet your aggravated, i hope you find out whats wrong soon!

:Cheer:

Yeah, I've got the thick cover now...Htt stuck it on there the last time I sent it in...

I appreciate it, it is very frustrating to say the least....But, It's all good....We'll get it figured sooner or later....

1 cp3?

have you ruled out a flat cam yet?
Click to expand...


Are you asking if I just have one cp3? I'm running PPE Duals...Floor It Stg. 2 on bottom and a duramax pump on top...

Have not rulled out the cam problem yet....Still not sure the best way to test it....Meassure valve lift right? or I guess you could measure just push tube lift height couldn't I??

The Cam is a Billet H2 that only has between 2k-3k miles on it at best!!!! Also I have run Schaeffer's 7000 semi synthetic and a Full bottle of F1 ZDDP ever since my build...Even changed the oil and put in a new bottle of ZDDP after I popped my first HG......I wouldn't think the cam would be bad.....

And yes, I did change the tappets....Don sent me the processed Tappets with the cam!!
 
Big swole, have you gotten this figured out yet? I had the same thing happen to me at my last run on the track. I know it isn't a head gasket, I have fire ringed in and have 625's on it. I get that same ticking sound from the driver side of my engine. I was also thinking injector because the truck had ran fine with the tuning the way it was, long before we hit the track. I also had a real rough idle until I turned the timing down, I gets clouds of white smoke sometimes at idle and it takes alot longer to spool up. Sometimes it seems to spool ok and other times it really lags. I never remembered it being this smoky ever...

Hey man!

Well, I will know more on Friday I hope......I just keep having more issues other than power....This last time, I blew one of the small little freeze plugs INSIDE the head....It blew a chit load of Antifreeze into my motor!!! I just installed the Dr. Performance Threaded Freeze Plug kit so this will never happen again....Might blow one of the block plugs but thats better than antifreeze in the motor!!

As for other things.....Well I found some galling on my rockers..one of my intake rockers was almost locked up!! Im not sure if this occurred due to the antifreeze being in there or if this has been happening over time......Got it smoothed out and am going to re-use..For now!!

Jeff Garmon just purchased an expensive Injector machine....He's getting into the fuel business now...Injectors and testing!! SO, He tested all of my injectors Yesterday....Found One that was WAY outta spec for return fuel....
The machine has two tubes that show the Amount of fuel delivered and the Amount of fuel Returned...All of them hit just above the 18 mark on delivery and were right around 3 on the return......2-4 is within spec on return.....The one bad one was returing OVER 10!!!
SO , THAT was one of my problems with power!!! We swaped in a good body with my Flux 3.8 tip on the bad one and then tested it again!! We got 18+ on delivery and only 3 on return........So THAT should help a lot!!

I re-lapped in my valves also....Just to make sure they were fresh while I had the Head off....

I finally sprung for some ARP 625 Studs and have them torqued down nicely now.....Will have to do a couple of re-torques to make sure before I Thrash on it....

Haven't checked the FCA's yet on my CP3's....I'm gonna wait on that until I see if Installing the Fuel Pressure Regulator ByPass will help the HIGH RP issue at idel.....I'll be able to turn the Inlet pressure down to 8-10 psi like it's supposed to be....

ONLY MAJOR thing I Really worried about now is if I can get this Engine Flushed REALLY well and Salvage my bearings!!!! That Antifreeze is NOT good in the motor!!


As for you, you need to get Jeff G. or someone to test your injectors!! Soon!!

Have you done a compression test??

Maybe bore scope the cylinders to see if the pistons look ok.....

I hope you get it figured out and its NOT serious!!!

:Cheer:
 
OH YEAH!!

I want to Thank Jonas at HTT for gettin my SS housing repaired with the new RonA Billet Puck system fix!!! Thats another fix that I'm hoping will hellp me get my Power, Spool, and Drivability Back!!!

Thanks HTT / Jonas
 
Did you have the converter rebuilt after you broke the input shaft? Is it the same stall, and the same converter? Does it feel like it is holding good?

A lot of the time if you have a hollow popping sound out of the intake, it is a valve issue from what i have seen.

Take a sheet of printer paper and hold it over your tailpipe. Make sure that the exhaust never tries to suck it back against the tailpipe and that it is always blowing it out. If it pulls the paper back towards the exhaust and blows it back out rapidly, then that can indicate a valve problem.

I had a boy bring me his 12v because he thought it had slipped time. It had a hollow sounding pop out of the intake and exhaust and when i pulled the valve covers, I found a pushrod jammed up beside a rocker arm.

Anyways, just throwing some ideas out there. Sounds like the injector could have been a problem though.

Good luck with it

Thanks man, but my RP seems fine...27.5K at WOT with MP8 up....
Click to expand...

I had sort of the same problem. All i can blame it on is rail presseure being to high. Max being around 26000psi. Didn't figure it out until i blew the solenoid right off the top of one. Sent all away to get checked and all had damage inside. Got a new set with bigger nozzles and voila' Runs like a champ now.:rockwoot:
Hope everything pans out in your favour. Good luck
