Not changed any yet and at £462 each even exchange I hope I don’t have to do too many. In Measuring Blocks 08 about display group 13 (I can’t remember exactly) there is a display for injector integrity and another that shows +/- correction on each injector. I would be tempted to change the head harness first.

The problem isn’t with the head gasket or the block, it is with the head.

What country are you in?
