smoke, smoke and more smoke!

[top_projects05]

Hey guys, I have a big problem with my 95 eclipse gst. It started smoking white smoke really bad from the exshaust a while ago, about 2 months ago. Since then i've replaced the headgasket and even the turbo and still it's smoking like crazy! I've read some forums already and some say it could be due to the vavle seals also... But then I want to ask you guys if you guys know of anything else i can do before going that far. I'm thinking replacing the vavle seals will cost a grip! I really don't have that much money.... can the smoke be due to leaks in the headers or down pipe? I don't think i tighten them enough maybe? What else can i do guys, help me out please. The other fourms didn't help me out much at all, I hope you guys can! Thanks.
