Frequently Asked Questions
What Is An Oil Recovery Pouch?
The oil pan's recovery pouch extends the right side of the pan out away from the crankshaft, creating an open pocket for oil coming off the rotating assembly to collect and drain into the sump. This thins out the heavy atmosphere of oil in the crankcase allowing the crank to spin easier thus freeing up horsepower.
What Is Baffling?
The baffling systems in Canton's oil pans are the result of extensive testing on all types of tracks and engine configurations. We use a combination of precisely positioned trap door baffles, oil runners, and slosh baffles to control the oil in the sump and direct it to the pickup. Trap door baffles are designed and positioned to open and allow oil to easily flow towards the pickup and close to prevent oil from flowing away from the pickup. When motion causes oil movement the oil runners direct oil toward the trap door baffles.
What Is A Crank Scraper?
The crank scraper extends out away from the pan mounting rail toward the crankshaft. The crank scraper is designed to catch oil spray coming off the crankshaft. Like the oil recovery pouch the crank scraper thins out the atmosphere of oil around the crankshaft and frees up horsepower.
What Is A Windage Tray?
Windage is the flow of air within the crankcase. Each time a piston comes down in the cylinder bore the air under it is pushed into the crank area and each time the piston goes up the air is being pulled behind it. At the same time the rotating assembly is spinning and churning the air and adding oil into the mix. The windage tray keeps the windage around the crank from the oil in the sump area. It allows the oil coming off the crank to easily enter the sump without the windage affecting the scavenging of oil already in the sump. The windage tray also keeps any oil in the sump from getting into the rotating assembly during vehicle motion.
What Is The Proper Clearance Needed Between The Oil Pickup And Oil Pan?
You can calculate the clearance by measuring the internal pan depth and measuring the distance from the block's pan rails to pickup bottom. The difference between the two measurements will provide the pickup to pan clearance. Gaskets will add some additional clearance. Here are some recommended pickup to pan clearances: Ford Pans- 5/16-3/8 inch (.312-.375) Chevy Pans- 5/16-3/8 inch (.312-.375) All Others 5/16-3/8 inch (.312-.375). Deep sump pan pickups are submerged deeper into the oil are less sensitive to clearances. Deep sumps may have clearance up to a 1/2 inch.
Should I Use A Mini Or Offset Starter?
These starters use a smaller and faster motor combined with gear reduction to produce increased cranking power in a package that is lighter than a conventional starter or OEM starter. In addition, they are offset to provide more clearance for the horsepower saving oil recovery pouch on our power pans. To determine what starter is best for your application consider the needs of your engine and your oil pan. Our oil pan descriptions call out starter requirements when necessary.
