Hello, my name is mike I'm new to the forum posting and diesel owning. I wrenched on diesel locomotives for about a year and a half but my 2001 silverado dmax is my first. I'm just looking for insight, problem solving and hopefully good upgrades. I hope to be able to return the insight to others after I learn to work on my own. She is completely stock and I already have a problem lost compression in cylinder two so here goes the fun.....
