STC Fitting

Ive got an 06 F-350 with the 6.0 and I believe I have a bad STC fitting. After doing a little research I seem to be having all the same problems that are related to the STC fitting leaking. Mine was running fine when driving around town but once I got up to speed on the highway it started to run like crap and finally died, and will not start at all now. My question is my truck has 200K on it and most people that I have read with these same problems dont have quite that amount of mileage on theirs, so I am wondering if that is where my problem is. I just bought the truck a month ago so I have no idea if it has ever had the STC fitting replaced. Also from what I have watched on youtube it doesnt look that difficult to replace the fitting yourself, just time consuming. Has anyone done their own? If so how hard was it?

I've done my own. It wasn't too hard

plan on a whole day of laying on your stomach which gets difficult if you're not used to it.

The changeing of the fitting is rather simple, the problem comes in to the getting to it. That is labor intensive. Like the man said be ready for a day of it.

Highly recomend some kind of padding to lean on that hood latch and stuff really cuts into the belly especially after a few hours.

Ya from what Ive seen on a few youtube videos its pretty simple to change the fitting, just getting everything else out of the way is the time consuming part. Thankfully Ive got a buddy who owns a small repair shop with all the right tools and equipment and we are both pretty mechanically inclined so I would think it would be pretty simple. Now is there anything else that I should go ahead and replace while Im in there. Im probably gunna put a new IPR valve in just so I know its done. Now how hard is it to put in an EGR delete kit? Also what is the best kit to go with thats not unholy expensive. (Im a college student)....

can't comment on the best delete kit but you will have an easier time getting the HPOP cover off with the intake manifold out and EGR cooler out of the way. I always upsell those fittings when i have the coolers off
