And then I found the culprit.

- drained the oil

- removed the airbox and resonators
- removed the throttle body and MAF
- removed the wiring harness
- removed the intake plenum
- depressurized the fuel lines and removed the fuel injector rail
- individually cleaned and serviced all six injectors
- removed the rocker covers and soaked them in degreaser overnight, then scrubbed them clean
- removed the intake manifold
- cleaned, degreased, and painted the intake manifold and fuel injector caps
- bought replacement bolts, washers, and nuts for the entire upper engine
- removed the drive belts, harmonic balancer, upper and lower timing belt cover, and timing belt
- removed the thermostat housing and thermostat
Back in February, my mechanic (ahem, former mechanic) replaced my thermostat. In so doing, he clogged the valve on the thermostat and absolutely crushed the end of the thing - God knows how. Anyway, the thermostat is shot, and doesn't open fully, which is why my XTerra overheated and blew my head gasket, amongst cooking all kinds of other components.
By the way, I never envisioned rebuilding the engine to include so much cleaning. SO MUCH cleaning. Obviously I have quite a ways to go. I'll post an update when I'm all done!
