So I started with what should’ve been a straightforward transmission swap on my '78 Camaro. I figured while the transmission was out, I’d replace the rear main seal. That led to noticing a small oil leak from the oil pan gasket, so I dropped the pan. Then I spotted some suspicious-looking metal flakes in the oil, and before I knew it, I had the heads off and discovered a couple of cracked pistons. Now I’m staring at a full engine rebuild and wondering how I got here. Anyone else have a simple fix that spiraled out of control? What’s the best way to keep these projects from taking over your garage and your wallet?
