No, don't push it over a cliff. Keep the van, so your worries stay close by, and you stand a chance of solving said worries. If you don't, your worries will be much greater, and harder to solve, and therefor more frustrating. You know, things like global warming, terrorist attacks, dropping baseball card values, things like that.

  Which heads did you use? 1.9 and 2.1 are different - they have different chamber volumes, and 1.9 heads will raise your compression ratio. Just hoping you didn't mix them on the same engine...

So, maybe I have piston slap, bad injector, and a clogged coolant
