ok so i went to look at a car today, its a 94 gsr swap eg, and when i went there was an oil leak coming from the vtec solinoid area all the way down over the b18c1 code stamp, it also looked like it was coming from where the bottom block n head meet the owner said the vtec solenoid was leaking and it jus needed a new O-ring.well vtec kicks in but smoke comes out of the exaust when you first gas it. any idea if the smoke is because of the leak? and how could the leak be fixed. and where could i take it to get a proper inspection over everything, engine tranny, brakes etc. thanks for help in advance
