well, I fixed the knocking noise.it was 2 things. I bleed the lifter that I heard was making the most noise(the one I accidentally took off during a cam install) then realized that the noise was mostly gone. then had this slight ticking sound, but already knew that was my exhaust leak(the stupid header stud that is all the way to the left facing to the motor that everyone complains about messing up.) My gas mileage still sucks. Heres an example: I put 5.2 gallons last week. I only drive exactly 6.4miles to work and back. I never went out after coming home from work last week.I'm on E now, only put 46miles. Thats like what 9miles per gallon???I know its short distance and I know some people will say only driving my car that short of a distance everyday will kill gas especially warming it up, but still this did not happen the first couple months I bought the car. Well, I'm just going to suffer through winter, buy the remaining parts I need for my swap, install it, and get it tuned so no more problems. and if having turbo will still suffer the same mileage I won't complain..its turbo.its fast.its wonderful..hehehehe
