i currently have a problem with the cylinder 2, leakdown test came out to be 20%, the rest are 15% and under, i was wondering would i need a hone or a bore? havent taken the motor out and was thinking about taking it to a shop to do the labor, serious help!
If its an earlier WRX I would bet burnt exhaust valve. But since its prolly a Pontiac Vibe who knows... LIST WHAT VEHICLE IS HAVING THE PROBLEMS, WE CAN'T READ MINDS
