sethmaxima

I found there is some terrible noise in my engine during acceleration.
I check it in Firestone. The guy said I need replace the motor(cost at least $1500).
Then I go to a Nissan Dealer(Armory) Service. They said replace the VTC Gears and Rear Manifold($1435+660+tax).
It is really a big buck for me
Anyone can give some advice to me, a poor maxima newbie(I only drive my 93 maxima SE for two months, faint)

93max

is the VTC and the exhaust stud breaking off. theres alot of VTC talk on the other forum and heard the ehaust stud is a b1tch to fix your self
use SEARCH keyword VTC
