I need help I have a 97 f-150 with a 4.6 in and whenever I take it on a longer drive like 45 minutes maybe sometimes just driving it for awhile it will do it, it starts to smoke not like alot but you can deffinitly see it coming out around the cracks on the hood, and when I pop the hood it smells warm, but the gauges read normal, and it looks like the smoke might be coming from the top of the engine, got any advice on what it might be and how to fix it, thanks.

 

did you spill oil on the engine at all or anything else that might be burning off when it gets hot?

If the answer is no then I would check your coolant level and if it's low start checking the rad hoses for pinhole leaks. When the truck is smoking it would be a good idea for you and a buddy to get under the hood and under the truck and look around for the source of the smoke

 

no there is no oil spilt on the engine, I thought that at first, it looks like it is coming from the top back by the firewall, by the intake manifold, and on the intake manifold there is 2 spots of soot like they have something burning next to them,, so I really dont know what to do
