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.
