Hi there guys and girls. My S3 is being tested later on to see if the headgasket is on it's way out as it has a few of the symptoms. If this is the case im going to be taking it to my dad's at the weekend and we will start the stripdown, im planning on getting it all apart on saterday and bringing the head back with me to possibly have it skimmed. How much will it cost to get skimmed ? how long does it take ?. Also any ideas where i can get it done. One more question i have does it cost alot more to get it ported / polished bla bla. Thanks alot in advance.
