Well I told you guys that i was takin my truck to ford to have the intake cleaned got it back yesterday they said nothing was wrong so they didnt do ****,,,, Today Haulin a wdx1203 swather check engine light pops up with these two codes so I go down to my local buddys shop hes gonna decoke my turbo pull intake off im sending it to machine shop to have it dipped and cleaned and puttin my bullet proof egr cooler in that should stop my egr vavle failure from twice a month to about twice a year and help my hard spooling problem hes gonna do this no charge so ima buy him lots of beer if coolant loss still shows that meens EGR cooler is out of the pic and straight to head gaskets i dont think oil cooler is bad cuz just changed oil yesterday and it was clear so it will be taken back to ford and there it will stay until they pull there heads out of there asses and fix it right but they did say if it came down to head gaskets they would put in ARPs if i buy um and it wont F with the warranty hes done it for other people i know of two so im good there but this EGR crap is a bunch of Bull Crap if you guys think something else could be causing let me know while i have it apart

 

Your oil screen could still be plugged. That's the point of the screen, so the gunk doesn't go through the HPOP. You wouldn't see any of this in your oil change. If you do the EGR cooler, I would dig a little farther and clean that screen or replace it.

I've seen both of these codes numerous times, they go hand in hand. To me it sounds like your EGR valve is stuck open. Have you tried removing it and cleaning it or replacing it?

 

its all torn apart right now EGR vavle stuck open about 8 percent scanner showed pulled out cleaned and holy shiteeee the intake was plugged im doin the CCV mod before it goes back together and ill see if the machanic wants to tare into HPOP to clean screen but today it was throwing two turbo codes one was underboost and the other was performance or something i dont remember what the numbers were and the same two EGR codes so Intake is soking in carb cleaner over night then pressure washing it out and reinstaling everything monday also cleaning turbo up while its off... but hell this guy knows his stuff had everything apart in an hour and a half so no complaints here just got him a case of beer and sat and watched him tear it down

 

Sounds like a good deal to me! Let us know how you make out with it.

 

P0404 and P1335 are both egr codes indicating you have a stuck or failed EGR valve. You are taking the right course of action by cleaning it (with CARB cleaner only) and cleaning the intake. Your oil cooler could still be failed. It has nothing to do with the color or condition of your oil. Oil cooler failures happen because casting sand from inside the block comes loose and plug the coolant passages in the oil cooler which also results in EGR cooler failure and can easily be mistaken for head gasket failure. Have someone check the difference in your coolant temperature and oil temperature. If it's more than 15* under load then your oil cooler is plugged and should be replaced. It also sounds like your turbo needs a good cleaning.

 

He has an SCT, so as long as he has a laptop or can borrow one, he can check the engine coolant temp vs. engine oil temp by himself as well.

 

holy hell i just got this SCT tuner I didnt know you could do that with it thats frickin sweet you guys are cool thanks for all this input im a little P O'd at Ford they took my EGR valve out to inspect and said it was fine and said my intake was fine to so Yesterday got it pulled apart and Holy cow INTAKE WAS PACKED and the friggin ford machanic didnt put a new gasket on my EGR vavle just used rtv silicone so the there was blowby all around the vavle and there was silicone splatered all over the actuating assembely of valve so i cleaned it all up it was indeed stuck open got it all nice and shiny and closing again its only a month old vavle so im hoping that the blowby didnt get into the little holes and F up the electronics of valve. indexed and pulled turbo apart and soking it right now with penetrating oil and gonna clean the ever livin **** out of it it wasnt that dirty but hell its off so its getting cleaned its only a month old too. also there was a slight exhaust leak on the turbo?? have you herd of this??

 

Yeah I have a little bit of an exhaust leak on mine too. Not a huge deal. Isn't it interesting the stuff you find when you start doing your own work on your truck?

You can always have someone weld that EGR valve shut too.

 

Ya It is interesting I also found a Bolt missing from the turbo to pedistal... But Got truck put back together Boosts great runs like a champ EGR vavle is functioning good and everything now just cant wait for my tunes to show up from Innovative..

 

Awesome! Good news brotha. When we did an EGR delete on my buddies 04 we also found one bolt from the turbo missing. When we got the turbo off, we found it laying in the valley there. Weird. I've heard of guys using the 03 turbos and mounting them to the newer pedistal and only using 2 of 3 bolts, since the 05+ pedistal isn't the same as the 03's
