Variable Vein Turbo problem

[hatcher1105]

Ok I was told that the turbo in my 05 F250 is a Variable Vein Turbo ( I dont really know much about it) and I was told that the variable vein is one of the first things to go wrong with the turbo. I was told that when it goes bad that you get no low rpm boost so when leaving from a stop you get a bad lag and then the high rpm boost kicks in. Does anybody know what I am talking about and have any suggestion on what to do because i have 80k miles and if it is a problem i need to get it fixed soon. Thanks for your help.

If it isn't broke then there's nothing to fix. If you have 80k on the truck and your tubo is working fine then I think you have a good turbo.If I were you I would keep doing whatever you've done to the truck for the last 80k.

well the truck runs good, but it does have a big lag before the turbo kicks in. So that is what I am thinking might be the problem with the lag is the variable vein?

Be sure you put yer foot in it once everytime you drive it and really work that turbo...thats what makes them last.
All the 6.0s in stock mode have a lag at low RPM - thus the reason for the dual turbos on the new 6.4
Get a tunner like an SCT and that lag will disapear.

I think your fine.
BTW your turbo has vanes your forhead has veins.

The Variable Geometry turbo uses oil pressure to turn a unison ring within the turbo, thus changing the pitch of the turbo. The problem is that the unison ring seizes to the turbine housing, sometimes open mostly closed though. If it sticks open, it will overboost and blow up the CAC. If you remove the turbo, the 11mm nut and split the turbo in half, you will see what im talking about, just clean the ring with die grinder/sanding pad, coat with Never seize, and perfect for another 25000 miles.Dont forget to reinstall oil drainpipe and tighten the CAC to 103in/lb.
