WHEN MOTOR IS RUNNING ITS BURNING GREY SMOKE FROM TAIL PIPE

Re: 89 JEEP COMMANCHE
 

Black or Grey Smoke results from incomplete fuel combustion caused by a
clogged air filter; carburetor, choke, fuel injection or emission system
malfunction; ignition timing off; or a blocked manifold. A vehicle with a
cold engine may also emit black or gray smoke, but not after the vehicle is
warmed up.

Grey smoke can also indicate a blown head gasket.
Check the antifreeze and the oil dipstick for signs of
the other.

Re: 89 JEEP COMMANCHE
 

This illustrates one of the problems making any sort of diagnosis over
the phone, email, or a newsgroup. His "grey" could be my "black",
"blue", "white", or "grey".

Other things to look for would be smoke coming out of the oil fill cap
when removed, bubbles in the radiator (Do not remove the cap when
hot!), unusual smells, or unusually rapid loss or consumption of fuel,
oil, or coolant.

What else is different about this engine?
