Well I bought a polo to buy and sell the other day with a snapped exhaust the engine management light was on which I thought was down to an O2 sensor and was obviously running rough etc. anyways got home sorted it and started up still running rough. Compression tested and cylinder 2 is obviously down being at only 30 psi. Read up quite a bit and have came to the conclusion of a burnt out valve/seat etc. I am just after any advice on doing these as if it's too much of a pig I might just sell on for a loss. I've never had anything to do with this engine so any help is great thanks!
