I've mentioned the findings to the prior machine shop and mechanic. Both respond with swearing, threats, and hang-ups. Both have weapons in the shop and a stupid redneck mentality. Most of the money spent was cash.

Additionally, when they are calm, they mention that I voided all warranty by having an expert look at the engine, but that they offered to "fix" it all a 3rd time prior to someone else taking possession of it.
