white/grey smoke?
Past few days ive noticed my car throwing thick grey smoke when i get on it. Also, my coolant level low light has come on? Any ideas what this could be before i get to the dealer?
. Only real mod is a 172 pulley.
TIA

Ouch... does not sound good....
If it was a one off I would say some carbon breaking off, but often I would say it sounds like gasket.
Open your oil filler cap and see if your oil is the right colour and not mustard.

So, cant get a service app till next week. Did some poking around, car was 1.5 qts low. Filled it up, no milky residue on cap. Looked around the engine, and saw there was oil on the under belly pan. Looked under the car, and there is oil sprayed on my exhaust pipes. Now im guessing theres been an oil leak which is getting on the exhaust. When i get on the car, the exhaust is heating up the oil on the pipes producing the smoke out the back.. could it be from the last person that changed the oil re-using the drain plug? so frustrated with this..

Walter, Sorry to hear about your troubles... Usually thick grey smoke and a blown head gasket are not related. Sounds strange 
Keep all the fluids topped off. Hope you figure it out bud.

Well, turned out to be a plug/bushing in the trans. Fluid leaked out, hit the exhaust, burned, and sent smoke from underneath the car.. Whheeew..
