That guy is right. I believe that your problem is more the value seals need changing and you'll need to grind the valves. This is the main cause for the white smoke. Oh and make sure your air filter is good it could need changing too

The alternator is used to charge the battery. There is no reason to believe the replacement has caused the fuel utilization problem, or smoke from the tail pipe, or rough running engine. A good mechanic should be able to examine your engine and find the problem. White smoke could be valves or piston rings worn out. There are many things that cause rough running engine. Fuel mixture controls, fuel leak, faulty timing, there is a long list. Good luck.

SOURCE: White Smoke that smells liek fuel, but not overheating

It sounds like the rings are washed out for some reason. any chance you filled up at a gas station with water in there gas ? if it was me I would do a compression test and see if it is low , and it sounds like it might be then leave the plugs out and put oil in each cly turn engine over a few times and let sit over night or at least serveral hours , this will free the rings up , fuel and miss fires will wash the rings out and running will get you white smoke , after oil has set in cyl now you have to clean it out if you have qa air compressor you can shoot air into each keeping a rag over so you dont make a mess, and you can keeping one end in hand send a rag down to soak it up, you will most likely have to pull the plugs out and clean them with break clean a few times till the engine will stay running once it stays running it will smoke until the oil is gone but the compression should be back to normal and cleared up it might smoke for over an hour once you get it running you can hold throttle to 2000 rpm as well this helps a bunch. but find out where compression should be and check it . I think some how either the missfire or bad gas. did you replace any coils or coil pack ? is the miss fire gone?

My 1998 Dodge caravan (3.0 v6 with 3 speed trans) was running fine until one morning I start the van and put it in reverse...nothing, put in drive, 2 and 1 and nothing. It can be pushed in every gear...

With the van in park or neutral with e-brake on, and engine running, pull the transmission fluid dipstick, notice there's no fluid on the dipstick. Put a quart of transmission fluid in the dipstick tube, with e-brake still on, put the van in gear. R or D, and see does the van try to move against the brake. If it tries to move, engine speed drops, put it back in neutral or park and check the fluid level again. If it's still low, put in a little more till it's to the full mark.. Done. Check under the van and find the area where fluid is dripping out and fix it. If it's the pan gasket, replace it. Replace the filter while the pan is down.

My inside light will not work on my 1999 dodge grand caravan and i need to know which fuse to replace so that htey will work again?

The fuse is located in the engine compartment buy the battery. Under the fuse box cover is the information you need to look for which fuse you should pay attention to, keep in mind that the fuse box in the engine compartment is know for corrosion so pay attention to the fuse box it self for corrosion. The fuse may be fine but the terminals that the fuse goes in to may be damaged by corrosion. Good luck and hope this helps, keep me posted. Be glad to help you get your van running with lights again.
