I have a 2013 GMC 3500 HD Dualie. The motor is blowing smoke out the back. I was told that one cylinder is low pressure. It has 300,000 miles on it. Any recommendations where I could buy a good quality long block mptor?

hello, looking for anyone that may have experience with this. I have a 2013 Silverado 2500 HD that had a duramax, the head gasket went on it so I found a replacement powertrain out of a 2015 duramax instead of repairing the head. mechanic got the motor swapped but can't get the engine running ...

I just did an engine swap on my 2006 LBZ I replaced everything that turns and supports the engine in any way shape or form I have a horrible whining sound coming from the front of the engine I suspect it's either the new CP3 pump or the new water pump gears it sounds just like a gear drive cam...

I need to know what i would need to do in order to get a common rail 5.9l cummins engine to work in a 2003 silverado 2500hd. i only really need to know about the electronics and computers. Or if anybody knows a place that does these conversions.
