OK..really stupid question re: ccv mod?

[howardtm]

I know..I know..just try no to laugh too hard ok? But..exactly what are the benefits to doing this CCV mod I'm always hearing about? This beast of mine, an E 550, doesn't have an intercooler so any benefit in that direction is moot. Does it help increase power??fuel mileage??, smooth out wrinkles and age lines?

[stump0331]

if im not mistaken, it is to prevent oil from blowing into the turbo

[sea71]

Stumps right. The way the ccv is set up from the factory sends all the engine oily gasses straight into the turbo. I have my ccv piped to the rear of the truck and once youve seen what comes out of the hose, then you know what it is sending back thru the turbo!!!

OK...whats the up side and the down side to this little mod. In a nut shell guys, I'm trying to figure out the most I can do in terms of getting better power and mileage, for the least amount of buck. After all this time being dycked over by Allegheny Ford on fixing this beast, mind you it STILL doesn't run right..better, not right, I'm so broke and far behind on my bills sometimes I think I'm ahead. So, whatever I can do for the least amount of cash the better. Am open to any and ALL suggestions (so long as it will increase both power AND economy....and btw...theres a black plastic box tied into the intake hose pre-turbo...doesn't seem to be connected to any sensor..any idea on what this IS and do I need it?

[stump0331]

the up side is that it reroutes the oil from going into the turbo, the down side is depending on how you route the piping you may have in cab fumes or unwanted smoke

as for cheap mods, you could do a zoodad mod=

zoodad

zoodad2


the diy intake=

diy

10k mod=

10k mod

and then you could delete the muffler and cat(if you have one) with straight pipe,

that should help ya a bit

ok...thanks stump. As for the "Zoodad" well, would work fine if this were an F series..unfortunately, its an E series, and ya got just enough room under the hood for 1 spit and 4 cuss words, thats whats making coming up with a better intake so daymn hard. About the only option is to cut a big freeking hole in the hood and fabricate some sort of "scoop" arrangement. I've got most of what I need to make a mold for a large air box, but frankly, I haven't got the stones just yet to be cutting my hood. Just finished the 10K mod..a bit more vibration @ idle..nothing severe, just more pronounced in the butt, a tad better performance wise but need to drive it more than 10 miles to really tell, same goes as to any mileage increase. As to the cat..this rig doesn't have one..its a commercial vehicle, 19,000GVWR so I doubt it ever had one..the muffler..well, I'm old, but not hard of hearing(yet) so I want to keep that, maybe go with a straight-through muff. As I understand it, they're not as quiet as a reg muff, but they allow a smoother exhaust flow.
thanks.

Without an IC there is no reason to do the CCV mod like most do. If you have the plastic tube that the CCV vents too, simply replace it with a 4" piece of exhaust tubing and then weld a bung into it and vent it right back into the intake. The whole reason to vent the ccv is to prevent the oil film coating the IC... without one there is nothing to gain other then the increase in air flow by removing the little restriction you might have with the POS factory piece.
