white smoke from ym 1993 Jeep Cherokee 4.0L
 

i just bought this 93 cherokee and it will not pass emmissions testing
that northern virginia has. i tried the stop smoke goo that you pour
in. i replaces the plugs and changed the air filter. im a a loss of
ideas. the smoke is like a white/clear look to it. not the type of
smoke that a dump truck puts out.

any suggestions??

What did the emissions report say? What were the readings?

Three things can cause light colored smoke.

Un burned fuel.
Oil burning.
Coolant from a leaking head gasket or something.

The first should smell like gas and I suspect you would know by how it's
running if that were your problem. The second would smell like burned oil
and your plugs would be oil fouled. Could be caused by a clogged crank case
breather. I've never smelled the latter. Also condensation on a cool morning
and cold engine can cause vapor like steam.
Post your test readings and maybe others can be more helpful,

Take it to a shop? As in, ask before dumping crap into the oil?

What's the oil on the dipstick look like? Just the usual black or is it
medium gray with some froth to it? A cracked block or blown head gasket
will let coolant into the oil and cause it to look milky. Likewise, when
the engine's cool, remove the radiator cap and look at the coolant. If it's
not the usual green (or rust) colored then the same thing applies. But if
the oil and coolant look normal then it's probably oil being burned.
Various reasons, none with cheap solutions; valve job, piston rings, etc.
