I would check the exhaust manifolds real quick before I took the valve covers off. you could have a loose manifold. maybe when you go around a curve your truck twist makes it leak a little more my v-8 s-10 leaks like you said all the time I am constantly tightening the headers on it. I may be wrong but its worth a shot.
