Hey guys, I’m looking for a good affordable shop that can do a basic in frame on my Cummins X 15. also I’m not very familiar with any of this. Does anyone know a good aftermarket kit that is reliable for these motors? The truck has 495,000 miles on it but I’m pushing exhaust gas into the coolant reservoir. We’ve looked over the EGR cooler and really couldn’t find anything so I was told it probably needs a new head gasket but if I’m gonna do that, I may as well just get everything else done. any information would be very much appreciated.
