Known to gm injector problems with chevy silverado vehicles. My injector cracked or failed and diesel went in to my engine oil, causing an over fill of 2 gallons. Oil was leaking out all over from my truck while I was driving. There are many other post about this problem and gm is aware but hasn't issued a recall.
