Direct Port Dissaster!
My direct port system went south!
I Never even activated it yet.
God forbid this should happen to you.

I have only 750 miles on the new engine, and poof...
Massive amounts of white clouds shoot out from the exhaust. The car is not running anywhere near normal, missing and sputtering. Scarry. Incredible smell was all about. Overwelming indeed. I was stumped.
I took the solenoid apart the other night, with friends of mine, and discovered the right side solenoid rubber seal was torn and failing. It was not able to seal correctly. This failure caused raw gas to be injected into the motor, massive amounts of fuel was being burned... vaporized.
Amazingly I never even powered the system up, and this had still failed. Unreal....I am thankful that the motor seems to be alright. Everything checked out normal.
Cylinder pressure .165-170 Thank God.
Like I said, I never even turned the system on and it failed. [/B]

Re: Direct Port Dissaster! (bruce1)
Bruce , now that you identified the root cause of the problem and resolved it have you had a chance to hit that 300 SHOT ?
I can't even imagine what a kick in the AZZ a 300 Shot must be... GIDDY UP !
:cheers:

This is a sad and very long story.
In a nut shell, after my experience, the answer is no.
Simply put, I am happy just to have the car back running.
Indeed I have had better times.
Bruce

Re: Direct Port Dissaster! (ICULUKN-C5)
so what is the white smoke from? If your compression is good, then your pistons are okay?
Pistons are functing ok, as far as I can tell.

Re: Direct Port Dissaster! (MelloYellow)
I thought rich fuel would give a black color of smoke?
Coolant white?
Did you check your oil for a milky color?
You sure you didn't go lean??

The oil was fine, just changed today.
But it was black indeed.

Re: Direct Port Dissaster! (ICULUKN-C5)
i know this goes without saying, but if you disconnect the fuel supply does it still blow smoke?
The motor burned off the excess gas vapor, but it took 15-30 minutes to clear up completely.

Re: Direct Port Dissaster! (bruce1)
This is the third NX DP system I have heard go south. That is why I went with the TNT system. Run a 300hp shot many times without a single problem.
Sorry to hear about your troubles. Time to rebuild and make better :chevy

Thanks Michael, the engine seems ok.

Food for thought:
Remember, before you have someone work on your car, check them out.
And check them out throughly.
Don't make a mistake like I did.
My system still needs pleanty more attension before I can get back to the drag strip....sub-standard quality combined with inexperience can have costly and long term negative effects.
Not to mention, it takes a lot of the fun out of racing.

No pump could take a 300 shot + engine, so I think you have, right.
But then , how can the fuel be injected during normal driving???

Re: Direct Port Dissaster! (bruce1)
Aren't you a long time customer of MMS
Indeed I am, but my latest experience has shown me that once again, I am only human, and yes, I can make mistakes.
Thanks for your support..... I appreciate it.

Bruce, do you have a spereate fuel system??

Mike:
I have a booster pump installed, but I am changing the system though... I am not comfortable with it, .. it is just not what I had hoped for.
It looks pretty bad too, embarrasing if you will.
The fuel rails will not fit on the engine anymore because of the way it was installed. This really bugs me.
Frankly, I wish that I would have never done this mod.
And if you look close, you can see where I had to disconnect and reroute (loop) the fuel line in order to bypass the soleniod because of the it's recent failure.
I am embarrased to show you these images.

Re: Direct Port Dissaster! (bruce1)
Hey Bruce, I'm thinking of doing a DP system on my Z28 and just came across this thread. I really like the look of your MMS/NX system. Would you consider selling it? I'm not crazy enough to run a 300 shot but I'm thinking a 200 shot direct port with an MMS forged bottom end will make for a 9 second slip! :steering: I've already run 10.6 with their 396 all bore motor, on motor alone.
Also not to start a fight or anything but I don't see how an NX solenoid getting stuck open is an installation issue. Seems like an NX issue to me? Be thankful it wasn't the N2O solenoid!!
