I have a 2007 B9 tribeca with approximately 107,000 miles. During my last service I was told that the head gasket will need replacing at some point in the near future. I'm not looking forward to dropping the $3,000 cost and am wondering whether to attempt this on my own. I was hoping to get some advise on whether this is advisable or not. I have very limited experience under the hood and am more than a bit hesitatant as I fear a project like this could be way more than I can handle. Thoughts on whether a novice should even attempt this type of repair? I would only consider if it does not requre lifting the engine. Thank you for taking the time to respond.
