Dubya Tee eff does that mean? Could that be my low boost, and lack of oil pressure ? definitely leaking oil, Like a blind man I missed it

I feel stupid, and Ticked, I Never had this issue before my injector swap, This isn't the first time I changed my filter at night..
So tomorrow ill get the degreaser and a flashlight and find out if its really cracked or what.. But I took a video with the lights if any body is interested

One thing after another

An exhaust leak before the turbine is probably the most common "lack of boost" culprit.

If you're leaking enough high pressure oil to cause drivability problems, it's not going to be a seep or small leak...your truck will resemble the Exxon Valdez.

Oh and "one thing after another" is just something that goes on once you start modifying things. It's just part of the game.

I have set the P1211 3 times now running on the 100HP tune. they all came under hill climb at acceleration at a mile high or higher. showing 31-34 Manifold absolute pressure. not sure what Bill has the trigger points for the code set at but it was about 61-65inHg on my AE scan. Bill I am open to ideas if you have any... Just haven't got around to looking at the issue. Cleared the codes with AE.. problem solved

I actually missed seeing what my boost was but my gauge was showing above 20PSI when I glanced up at it...

EDIT: I just remembered i wrote down the DTC results from the last occurance on my BlackBerry but didnt put down the rpm throttle data etc as i was driving at the time

Ok, Its leaking, and I'm probably low on oil now, But its not pouring out..

basically this small crack couldn't cause much of an issue?, Besides making a mess and making me have to replace it..?
sadly I was hoping this would be my main issue!

Got to Pay to Play I guess ? But come on a leaky valve cover?!

here it is.. Any other way to maybe seal this? Or should I order a new gasket/cover?

[bamboo]

So got me a new cover and changing it today, any body know torque specs on the cover bolts?

hoping I dont have to take the intercooler tubes off

Thanks

Mahalos Chuck!

Do you or any body know if its Normal or OK to have Oil in the UVCH? connectors ? that go in the V/C gasket

[bamboo]

so.. dont know whos all reading this.. But I broke one of the UVCH? connectors inside the cover, It was all melted together, Same one that had Oil on the outside..
I assume this is bad, What could cause this ??

And where can I get connectors? can I just splice and replace um ??

Mahaloz for any info here is one picture

I would recomend going down to NAPA and picking up a new harness assembly. I cant remember which side is which on those plugs, but I think it is the glowplug side that crispied on you. how did the other plug look? they have a kit that replaces the whole kit and kabodle except you need to splice into the wire harness to replace the outside plugs.

Check your glowplugs while you are there to make sure they aren't the culprit and drawing to many amps.
