Edit: deleted pics of vehicles not in your shop. Looking forward to seeing some more of the trucks coming through your shop. If the two you posted are any indication this is going to be a killer thread!
Thanks to Marshall and Greg, took the wife's 4runner in on monday and had the valve cover gaskets and spark plug gaskets replaced and the brakes done. Drives like a new vehicle and has a lot less rattles. Has 228000 on the odo and the top end looks great, no sludge so hopefully I'll pull out another 228000 out of her. Thanks again guys!
