Order the Wehrli Custom Fab WCF100131-RED Aluminum Oil Pan - WCFab Red from GAP for your GM 6.6L Duramax LB7/LLY/LBZ/LMM today. WCFab X PPE's Duramax High-Capacity Cast Aluminum Engine Oil Pan replaces the poorly draining stock steel oil pan with this flat bottom high-capacity oil pan. The stock pan has a valley in the design that sucks in nearly a quart of your dirtiest oil and immediately contaminates fresh oil after a fresh fill. This deep pan has been engineered with a flat bottom to ensure all oil is drained properly during a service.
The stock engine oil pan is made of stamped steel, which offers very poor heat dissipation. This upgraded pan is made from cast A356.0-T6 aluminum for added strength and optimum heat management. The extra quart of capacity provided by this product helps reduce oil temperatures, increase oil pressure, and provide better lubrication to your engine's vital components. Unshrouded oil pickup results in less restriction near the pump than OEM, resulting in higher oil pressure and better lubrication.
Includes:
Fasteners
Pan
NPT Plug
Billet Stainless Steel Neodymium Drain Plug

Works great
Be careful NOT to get it on painted surfaces it will remove the paint. It does exactly what they say it does and if you follow the directions to the letter you won't have any problems

Worth the time and effort.
Perfect solution to my faded out, sun damaged gel coat. Follow the instructions to the letter for a factory-like shine. One bottle was barely enough for our 22' Winnebago, another bottle for our 29' Cabin Cruiser. Many compliments on the shine.

A quality product which will clean an oxidized fiberglass trailer in preparation for the application of Poli Glow
I used this to remove the Poli Glow previously applied about two years ago to my fiberglass trailer. It seems to do a slightly better job of removing the PG than the other Prep solution, but I didn't do a side-to-side comparison. And the surface never achieved a completely uniform appearance after the stripping, although this may not be possible because of differences in the remaining gel coat surfaces. I also completely washed the trailer with soap & water after using this stripping product. I didn't do this the previous time and thought some of the prep compound may have been left on the surface resulting in a shorter life. Time will tell. Note: it is still "work" to strip the trailer, this is not a "magic" solution, thus the 4-star rating. But it, along with the Poli Glow, was the only way to get my oxidized trailer to look shiny. All the other products tried failed to bring a glow. I will purchase it again when redoing the trailer.
