Re: Smoking at HIGH RPMS?
Look closely at the tailpipe for any signs of condensation,
oil deposits etc. Run your finger in it.
Look at the smoke - white and dissipates quickly?
Most likely water/coolant - often the condensation appears
greenish and sticky. Head gasket etc
White but does not dissapate fast - reddish deposit?
Auto tranny? -- Vacuum modulator? Look at vacuum hose
at tranny, fluid inside?
Blue - hangs around a long time, doesn't dissipate fast?
Oil smoke - tailpipe may feel greasy. PCV clogged or
sucking oil out valve cover (no baffle,) oil rings,
oil leak into intake on Vee configurations (ie: V6, V8 etc.)
Blue smoke, greasy feel, - on hard acceleration, but more
on hard deceleration (high vacuum,) and at cold startup makes
a big puff, then stops - valve seals.
Have a look-see at the plugs to see if it's coming through
Also check for external oil leaks onto exhaust - more that
one engine has been rebuilt because of a simple leak or
