Hi Tom,
This is what I have been =
experiencing lately:
Vehicle starts up and idles fine, then =
discharges whitish exhaust, tailpipe is wet and sooty. With engine warm =
this diminishes somewhat which previously led me to believe moisture was =
due to condensation in the exhaust system which evaporated as engine =
temp increased. But, now I think there is a consistent internal leak. No =
evidence of any external leak.
Under load engine exhibits =
intermittent misfiring. Much has been said about this symptom on the =
list i.e. possible causes being defective temp sensors, O2 sensor, AFM, =
idle stabilizer, Hall sender, fuel pump, injectors, vacuum leaks, poor =
grounds, etc. I've checked out all these and they're ok.
That =
leads me to this:
A unknown amount of coolant probably small but =
consistant is migrating from water jacket via faulty rubber head gasket =
into combustion chamber. This builds up and fouls the mixture causing =
misfire, discharge of moisture (whitish exhaust) and unspent fuel (rich =
odor). Haven't as yet experienced the dashboard sound and light sound =
show you experienced, then again I haven't been driving much =
either.
This, unfortunately is starting to make sense to me or =
maybe it's fortunate because a head job will afford me yet another =
opportunity to become even more at one with my vehicle. Does this make =
sense to you? Thanks for asking.
