Just bit of an update for everyone garage have said they are prepared to do work themselves under warranty. Car is going in 2moz for proper inspection by themselves. To be honest don't really want them working on engine but I have to give them the opportunity to inspect properly and sort themselves. Ideally want them to make me other for contribution so can go to a specialist for work done as even if they do the work themselves I'm still going to have a rebuild with specialist to make sure all done right. Saves wasting their time and mine?
