well i havnt been on the board in a while b/c ive been playing with my new 88 turbo coupe. anyway i have some crappy news from the inline in my stang. here are the results from the wet and dry compression test i did dismorning. tell me what you think.
cylinder dry (psi) wet (psi)
#1 130 120
#2 130 125
#3 131 136
#4 152 140
#5 125 129
#6 116 109
2 of 4 cylinders went up when i injected oil into the cylinders. the rest went down. so obviously # 3 and 5 need rings b/c the blow by. but why would the compression go down thats what I dont understand. looks like #6 is shot. also all plugs had a substantial amount of oil on them except #3. this is the reason for the test b/c plugs were fouling above 3000 rpm. but the motor still runs just getting tired of replacing plugs every three months. time for the new turbo 3.3 to get dropped in.
