Hello everyone. I have a '95 318ti and it is not running I bought from someone very cheap because it was overheating. After some diagnostics, I decided to replace the head gasket. I hit a stumble putting it back together as the engine time is different from any other that I've done. I have researched and found that I need an alignment tool and was able verified that information on this wonderful website. So, here's my question, is there a difference between the $89 one and the $400 one. I dont normally like buying tools I get to use once, but I put some work into this thing and would to have it running. Would love to hear some feedback.
Thanks
