Can anyone tell me if not reinstalling the upper manifold brackets on a 2013 jeep wrangler could cause severe issues? I have been having some issues at the dealership last time I had work done they never reattached the upper manifold brackets. The dealership replaced oilcooler and the next day oil was just pouring out of the jeep. I had it towed back to dealership. They had said the bolts stripped out of the head gasket and had to put helicoils in. Oil leak never fully went away and progressively got worse. I decided to bring it back to dealership and they said now it was rear main seal and wouldn't cover repairs after I asked to have them replace the bolts and brackets that they forgot to put back on I get jeep back still no upper manifold bolts or brackets. So I am really curious if that could cause some major problems with the engine and if they should be liable for the repairs.
