So, what are some symptoms that I need to rebuild the engine? The other day on a cold startup I noticed some black exhaust, I was just trying to start the truck to move it up onto the ramps so it wasn't warmed up or anything. Other than that, it seems to drive reasonably well. Definitely feels like an old truck but no knocking or anything like that. Never seen any white exhaust so I don't think I'm getting any oil in the gas, but the black exhaust makes me wonder if I'm getting a bit of blow-by. It's not an every time thing, and at the time I attributed it to just giving it too much gas on a cold start.
