Default Friend'* Impala blowing smoke

My friend left me a voicemail. His 2000-something (2003?) Impala at about 100,000 miles is blowing white smoke out of the tailpipe. He was wondering if it was a head gasket.

I played phone tag and left him a voicemail. I'm not sure if he has the 3400 or the 3800 (I think it'* the 3400), but I told him that the 3800 rarely blows its head gaskets.

Has anyone had this problem with the 2000-something Impalas?

It definitely sounds his UIM or LIM is leaking. Are those as much of a problem on the 3400, too?

The 3x00 have intake gasket problems that would cause this.

Oh well, at least we 3800ers aren't alone.

I shot him an email and told him it'* more than likely the UIM, given the white smoke, and pushed him to get metal LIM gaskets installed at the same time.

The UIM'* on 3X00'* are metal. So only the gaskets are needed

So the 3400 got a metal UIM before we did... Lucky.

I saw metal LIM gaskets for it; are there metal UIM gaskets to match?

I would be lead to believe you can get it as a whole kit.
