pulled my intake today and found this. ive had the truck about 2 and a half years, NEVER ran with out a filter or even touched my intake for that matter. im assuming the previous owner had some sort of intake on the truck. all the bolts that hold the lower air box are MIA, and you can just tell when something has been tinkered with.





i clean the tb, it was completely caked on the inside, as well as the intake manifold. wtf do i do now ? the truck runs good, throws no codes, even compression ect. im worried about what the valves and pistons look like.

Nothing to worry about..very common..That would be the good ol EGR (puts exhaust gasses into your intake) and pcv system (puts blowby into your intake)

Thats is why I deleted the egr and have catch can......

jeffz0rz

so thats not dirt? seems like i need to search for some egr delete info. i was blown away when i saw this. this has to mean my valves looks the same way, correct ?

yeah, they probly look pretty nasty. but it shouldn't be anything to worry about. unless its really high mileage, they'll keep running fine. you can thank the EPA for all that nonsense.

umm isn't that a DBW throttle body with no EGR?

sometimes intake crud can also be related to the PCV valve hence why people install catch cans.

I like to put a little grease on all of my rubber boots on the intake connections to make it a tighter seal.

yes, i have a dbw tb. AND i think i f'ed something up. im getting 0107 and a 0443 code.

jeffz0rz

that stuff doesn't work. ive been drinking it all day and my truck is still throwing codes.

Double check everything you unhooked/cleaned and make sure its correct.

We're you having these problems before? If not then something is not connected back properly or was damaged during cleaning.

didnt have these before. im thinking i didnt plug something back in. guess ill be checking everything in the morning.

jeffz0rz

checked everything this morning, and its all plugged back in and hooked up properly. not sure what else to check. i did the tb bypass, its the only thing i changed. that cant be throwing a code though can it ? dis connected the battery, then im going to drive it a little to see if anything clears up. not sure what else to check. any idea specifically where to look since im getting those 2 codes ?
