Air in diesel system?

[KLP 92]

seems strange that they would go to the expense of replacing the head FOC if there was nothing wrong with the old one. Methinks that they must've botched removal of the broken plug, but don't want to admit they did.

Props to them for replacing the head and not trying to dodge the issue though!

It took a bit of gentle persuasion, combined with numerous visits, and the fact i had a second opinion from another garage helped!

Alot of hassle though, but at least i have a sound engine that will give me no probs in the near future!
