Hi all thought I should introduce myself as a new member. I currently own a classic Impreza jdm import. Since owning it the headgasket was suspected to be gone. So I got it picked it up by a recommended specialist, he fitted a replacement engine that had a recent rebuild. But this fiasco started in November and the last contact I had was in January and I can't get in contact with him. Sorry for the long post, I'm just after some advice on what I should do or if anyone has dealt with him before and has trouble. Not sure I should name and shame
