I was just wondering what do you guys think it could be, almost everytime i hit vtec you see blue smoke come out of my exhaust. I did a leakdown test on the motor and foudn it 6% leakdown. I also did a compression test on the motor and was pretty good. Do you guys think its the valve seals? If it is, how hard of a job is it to change the seals. The motor is a d16z6 sohc vtec.
