Back on topic, your problem lies with the builder for sure. You should have tried to get your money back and take it somewhere else. 5 months to do a build is fucking ridiculous unless you are building a monster with tons of fabricating. The builder could be fucking up tons of things, and who knows what really went wrong, it could be chewing up bottom end bearings, not circulating oil, or just put together piss poor. Im sure if he had it for 5 months he wasnt working on it every day so who knows what he might have forgot to do/tighten or thought that he did. Hope it all works out for you.
