I have a 1997 ranger 4.0 ohv that is blowing white smoke from exhaust on start up. I checked for leaking head gasket using a block tester found it did not have a leak. Removed upper and lower intake found that the lower intake manifold was very worn rubber was coming apart around the coolant ports. Replaced lower manifold gasket and put everything back together thinking it would be good to go. I drove the truck until the coolant that had leaked in there before was burned off and smoke had gonna away. Parked the truck for the night and when I went to start it the next morning it started smoking again for a while then went away again. I’m not sure what to do next any help would be appreciated.

 

Did it cease "white smoking" quickly? Maybe you were just clearing the normal moisture created by combustion?
I'd mark my coolant level when hot and shut-down and in the morning when things have cooled/contracted.
Use removable tape to mark the reservoir as you'll quickly mark up the bottle with a bunch of squiggly lines from a marker.

 

No it took a while and some driving to clear out but I will definitely check out the coolant level tonight and see how much I'm losing

 

Checked reservoir, looks like it's dropping pretty good amount. Pulled spark plugs and cyl 1 and 3 are pretty clean and wet while cyl 2 looked dry and normal. Other bank cyl 4,5,6 all plugs were soaked in what smelled like coolant
