2002 Altima eating oil

[tigersharkdude]

Posted for a friendI was just curious if anyone else has an altima that eats oil? My sisters car is a 02 and its the 2.5 4cyl. qr25 maybe? anyways besides the usual air pockets that develop over time in the cooling system, it eats oil.It don't leak a drop of anything and don't smoke ever. I don't know where this **** is going. I've had some LS1s that ate oil too but it was PCV troubles, and this thing don't look to have a PCV system on it....at least from casual glances. i'm not talking a quart between changes here, i'm talkin a few quarts a week. She will come home from cookeville and it won't even read on the dipstick after I put 3 quarts in it the week before.
