Apparently, this 2016 Chevrolet 2500 LML Duramax decided the valves needed a closer relationship with the piston. 😬

It came into ZZ Diesel after making a metallic noise, locking up, and refusing to turn over. Pulled the cylinder head and found a collection of broken valves, snapped stems, and metal chunks that definitely weren’t listed as factory options.

The piston looks like it lost a fight with a garbage disposal. The valves have resigned from their positions. Everyone involved has stopped working.

For anyone wondering, no… a new battery and clearing the codes won’t fix this one. 😂

Cooler temps, colorful skies, and plenty of Power Strokes in the shop. Not a bad view from the office. 🤘

2020–2024 GM 3.0L Duramax (LM2 & LZ0)
The Forged Diesel Products Billet Fuel Cap is designed to seal the filler neck, helping keep dirt, dust, water, and other debris out of your fuel system while adding a premium, machined look under the fuel door.

🚨 Stop A/C Refrigerant Leaks Before They Start! ❄️🔧

Your factory plastic A/C caps only keep dirt out—they don't actually seal the system. A/C QuickCaps™ feature a high-pressure O-ring that seals directly at the valve opening, helping prevent refrigerant leaks and keeping your A/C system performing its best.

✅ High-pressure O-ring seal
✅ CNC-machined billet aluminum construction
✅ Quick, easy installation
✅ Universal fit for most R134a systems
✅ Perfect for Duramax, Cummins, Powerstroke, and more

Watch the video below to see how these patented caps add an extra layer of protection to your A/C system.
