My headgasket went friday night ,car was running perfect then just lost power ,turned out to be a split in a hose ,.i got car to garage took head off it was the head gasket ,we inspected the bores ,and got a bit of wear on them ,engines done 120,000 miles but as plenty of power starts excellent ,ive only had the astra 8 days .question is would it be ok putting a new gasket and skimmed head back on , ive only done 500 miles
