test/remove/replace battery; oil change; transmission fluid; power steering fluid; replace serpentine belt; fuel injection service

In mid-October, my truck wouldn't start and I had it towed to Wayne's. He'd done work on it in the past and always seemed fair and good. The truck was looked over and I was given an estimate for numerous items that needed attention. Service was prompt and seemed alright on the surface. The truck was not leaking oil prior to being serviced in October. Since then, I have a huge oil stain on my garage floor, and even smelled burning oil while driving about a week after having the services done... $520 later. Today I returned to have it checked out. I'm now being told the valve cover gaskets are leaking, and the transfer case is leaking heavily. They were unable to provide me an estimate while there, instead telling me I need to return another time to have an accurate estimate done (across town, mind you). I'm not clearly understanding the attempted explanation as to why this wasn't occurring before they performed the work and oil change, and/or why it wasn't noticed when they did diagnostics on the truck to begin with. Bottom line, I no longer feel they stand behind their work and truly feel like I'm being taken advantage of... seems they just want MORE money! I will not be returning to Wayne's ever, and I don't recommend them to anyone else at this point!
