After I've been driving and the engine is warm, my oil pressure gauge at idle registers at 21 psi when driving it goes up to 60 psi. I have a slow oil leak in oil pan gasket.

My question is, 21psi at idle to low and should I replace gasket now, I would like to wait till first of the year before doing that. I had a garage look at it and they thought it would be ok.

20 psi at idle isn't a big deal. As for the leak if it isn't that bad you might get away with simply torquing the pan bolts. At least it's a 2WD, those are much easier than the 4X4 rigs.
