Hello guys this is my first post and first duramax. I own a 2004 lb7 with Allison. Truck is a peach with out a spec of rust or body damage. Currently has 200,000 miles. I'm going to soon find and make a post about an issue I'm having with injectors. It starts to smoke after it warms up so I assume I have an injector leak. What leaks? Is the cup bad or is it the injector it self?

I'm trying to figure out if it's a sticking injector i bought a bottle of Lucas and diesel injector cleaner. Dumped 3/4 of it in my tank and I'll see if it helps. I know it smokes like Cheech and Chong when it gets to operating temperature

Injectors are probably leaking.

Is that something I can just rebuild when I pull them out or would you just recommend buying new ones. Also what do you think of this
