Turbo o-rings..

Recently replaced my compressor wheel and lost about 10 lbs of boost, i took off all the boots cleaned them and replaced the turbo to y-pipe o-ring and gained about 4 lbs more. I'm wondering if the compressor housing has a o-ring in it as well? i didn't really look when i took it off. And the truck is running really hot. before the daily tune would just touch 1200 and stay right around there at WOT, now it hits 1300-1400.. so i'm thinking i've got a leak somewhere.
thanks, mitch.

i believe there is a gasket or oring on the housing that must be replaced when opening to change wheels or what not .....was looking at all that the last few days and wanna say its a $6 oring

Sold 01 350 6" on 37's and mild mods, 00 X 4" on 35's, 02 f350 4" 35's molded from fan to drive shaft, ridin the 03 with nose conversion with 125k and counting upwards slowly.
Never had CNC on any of it, never will.
Take 3/4 of the info and recommendations on here with a grain of salt

Yes sir, there is an O-ring on the housing. Watch this and see if you did what they did:

But, i do remember putting that o-ring in with the y-pipe and the housing still on the turbo so it may have not seated all the way, i'll double check it sometime this weekend.

there is an o-ring that goes between the main compressor housing and the compressor back plate. Every site i have seen it on it is an additional add on piece , it does not come with the kit. Look at guzzles page and you will find the o-ring. Would think after opening up the housing that you would have to replace this as it would be pancaked out
