exhaust smell ?\'s Well I've been driving the K5 some lately, and wondering why I smell like I've been working in the shop all day when I get out. The hardtop is on, no seals to speak of. but the floor in the back does have a few small rust holes (no bigger than a figer can stick thru) probably about 9-10 or so, in the corners. Think I need to adjust the timing some but otherwise, what gives? there's guys that have these with full restos and they don't smell when they get out do they? The floor is bare right now, no carpet, liner or matt.
