Hi my dads in a bit of a pickel, wot to do, he got a 1.9 tdi 110hbp and lossing water so took it to seat and they said the head has gone plus timing belt needs doing so they told him to not bother fixing it down to cost, so i took it to good cheap garage compared to seat and they did tests and they would TRY to fix it With the head being skimmed and new bits and bobs + timing belt all for 500 quid BUT they said it might not work. only 50% chance of working other than that the car is in good condition with 120000 miles. Should my dad take the risk of lossing 500 quid or scrap it. Some engine advice much needed, has the engine had to much damage to be repaired?
