Have 2 problems. Have 2 trucks both with 3126 CAT engines. 1st problem a 1999 Chevy C6500 Flatbed that is going thru oil but its not leaking anywhere. Where is it going? Not in the fuel or in the filters or anywhere that I can find.
2nd problem a 2000 GMC C6500 MD Wrecker that smokes like a freight train when it is first started. Thinking of changing the injectors. Any suggestions before I start?
