Question on motor
Right now im running a 96 GSR motor with a 4-1 header, Skunk 2 mani, and a B16 tranny. when i get up around 5.5k-6k rpms i start to blow some smoke out the back. Im wondering if it was b/c the Stock P72 is adding more fuel b/c of the secondairies. I ran a compression test and it came out 200, 180, 200, 200. Could it be that i have bad rings on the 2nd cylinder? I ran a leak donw test and i ran about 20% for all 4 cylinders. Any help would be great. later down the road im planing on getting a VAFC. Will this help by tuning down the fuel on higher rpms?

do you do a wet and dry leak down test?
also what color is the smoke.
anything 180 and above is correct on the compression test according to ALLdata
edit: I ment a wet and dry compressoin test :doh:

compression seems ok...I would bet your valve stem seals are leaking. Also you should do that compression test again, then pure a cap full of oil into each cylinder and do the test again....if that low cylinder matches up with the rest, than it means the rings are going on that one cylinder.
