# 3ZVE Blown Head Gasket
Blew my head gasket in 2003.
## Head Notes
These tips are nothing special; as much notes to myself as anything else...
- To check if your valves are seating properly, turn the heads upside
down and pour kerosene on the valves. If it leaks, they're not seating.
- Use lacquer thinner to clean the heads, intake, etc. It evaporates
cleanly, leaving no harmful residue.
- Before bolting the rebuilt heads back on, coat the bolts with
silicone. This helps prevent binding, so you can get a more accurate
torque.
- When bolting the heads back on, tighten the bolts in 3 passes (and
in the order specified in the shop manual): First pass, 15 ft/lbs
below spec; second pass, 5 ftp/lbs below spec; final pass to spec.
## Pictures
Note the spurting antifreeze, red Utah dust, ... and carbon deposits and burnt valves and blown head
gasket. Shit.
Prior to rebuild:
Timing belt and air intake off:
Crankshafts off:
