I have a 54-reg Nissan Patrol 3.0. During January this year I had a head gasket failure. I put it into an independent garage that boasts of savings of around half the main dealer labour charges. They used Nissan parts but now, five months later, it has gone again, and I am now faced with another £2000 - £3000 bill. Lots of people have said that they should have skimmed the head and had it pressure tested. I was not given the option of either, but when asked about this they said that were only trying to save me money. They are coy about any kind of warranty on their work, and when asked for a further quote, they have yet to respond. I am the loser but it's my word against theirs. Any ideas?
