We took off the breather cover on a 2004 chevy trailblazer and there was water in it


Sounds like you may have a bad valve cover gasket. same thing was happening on my wife's Chevy Aveo. Valve cover gasket was worn and when I replaced it and cleaned plug wells, issue was resolved.As for the breather, I really wouldn't know why there's water in there.Only thing I would suggest there is to check your antifreeze level. Is it water from the antifreeze?

2002 chevy trailblazer check engine light went on, took it to autozone they said it was a misfire in cylinder number 3, and that I needed to replace sparkplugs and wires. could this be the problem?"


Yes it could but without further diagnosis it's difficult to be sure. Manufacturers suggest platunum spark plugs be replaced after 100,000 miles. If your close to this it would be a good idea to change them anyway. While spark plug wires can fail they don't normally wear out like spark plugs. They can very easily be checked with an ohm meter. I wouldn't replace them unless I found a problem with one or more of them.

Check for these:
  • Bad spark plug wire;
  • Bad or dirty contact in distributor or multi-coil terminal (you may also have a loose plug wire here);
  • Fuel injector clogged or not operating reliably.

Location of the spark plugs?


Remove the air cleaner outlet resonator from the engine. (the plastic thing in the middle) the coils sit right on top of the plugs. Disconnect the ignition coil connectors, then remove the bolt and pull out the coil. the sparkplug is at the bottom of the hole :) remember to torque the bolt back down to 89 in-lb (10 Nm) and use alittle dielectric grease on the end of the boot. and finally dont forget the anti-sieze compound on the threads of the new sparkplugs before installing :)
