i just bought my first stang , its a 3.8 , i only gave 1,700 for it because they had no idea how many miles were on it , but its in good shape just needs a little tune up , so i was going to seafoam it , but not just by pouring it in with the gas but by letting a vacum hose suck it into the valves little by little and watch the smoke show , but im not sure witch hose goes to all the valves , and ive read that it has to bypass the check valve to be done right , any help finding this??? its a 95 mustang 3.8 , only mods im aware of is the cold air intake
