The Hump

the_humpPart of your Duramax® diesel engine’s dirty secret is that it’s got a HUMP. The hump adds volume, so you can have more oil in your engine, but because 2 cups of oil are trapped in the HUMP, the oil gets filthy really quickly. Within minutes of running your engine after a fresh oil change, the oil will look black again.

The ONLY way to get rid of that filthy oil is to get a new oil pan without the HUMP.

FAQs

Why do I need a banana pan for my Duramax?

The Stock lower Oil Pan was a compromised design and the “Hump” made by the transverse frame member traps over two cups (two-thirds of a QUART!) of un-drainable, used, contaminated oil in the crankcase at service time.

If you like the idea of making your truck the best machine it can be, then the banana pan is a sensible one-time up-grade for you.

Can I install the banana pan myself?

If you’re reasonably handy around machinery and enjoy working on your own vehicles, this is the perfect project for you. It’s very straight-forward, using a dozen or so mechanic’s tools and following the directions ( with a little common sense) the actual work time is three hours tops, but you need to take at least TWELVE HOURS to let the sealant cure so there will be no leaks (the $16+ AC Delco factory sealant is included free in the kit).

The best way is to drain the OEM pan, remove it and let the Duramax© drain overnight. The next day, install the banana pan and let the sealant cure for twenty-four hours before putting fresh oil in the engine. If you’ve ever changed a water pump or an exhaust manifold, this will be about the same degree of difficulty. You just need to be patient and careful with the factory sealant. It’s amazing stuff, but IT NEEDS A DAY TO CURE! Check out the installation video below for a detailed step-by-step, or download the printed instructions from the “Videos & Downloads” section below.

How much Oil Capacity will I loose?

The banana pan eliminates the “Hump” and facilitates complete sump draining. The 2+ Cups that were trapped in the sump will be gone and you will effectively loose about one cup of volume. If you install a remote oil filter you will regain that capacity and then some. The space around the Duramax’s lower oil pan is very restricted and there is really no space to expand the lower oil pan to gain volume.

What Options are there? Can I get a special color?

The Basic “banana pan” comes powder-coated in yellow, that’s it. If you want one you can paint yourself, and want one before it goes to the Powder-Coater, just ask. We will be offering a 110volt “Heating Pad” Option and/or a 3/4″ NPT Hole for a bolt-in heating element soon.

How can I tell which Series of Duramax© I have?

Check the EIGHTH DIGIT in the VIN Code, and refer to this list:

  • VIN Code “1” is a 2001 – 2004 LB7 (17-Hole)
  • VIN Code “2” is a 2004.5 – 2006 LLY (17-Hole)
  • VIN Code “D” is a 2006 – 2007 LBZ (17-Hole)
  • VIN Code “6” is a 2007.5 – 2010 LMM (17-Hole)
  • VIN Code “8” is a 2011 – 2015 LML or LGH (18-Hole)

Will installing the banana pan void my Warranty?

Probably, although it does not effect anything on the truck and makes the Lubrication System BETTER it will still be a fight especially if a claim is oil or lubrication related. There is a “Low Oil Sensor” on the Duramax© Diesel that re-installs when you switch to the “banana pan” so you still have the same level of protection for your engine.

I lifted my truck 9 inches, did a wild paint job ( $5600 ), swamper tires and wheels ($2400 ), an expensive sound system, and suspension work -- I’m out of money, but if I tell my friends about your cool banana pan can I have one for free?

No.

Why do I have to wait so long for the sealant to cure?

It’s just the way it is. The AC Delco sealant which we include for free with the kit, is awesome stuff, but it needs a day to cure so that it will be oil-tight for the life of your truck – just the way the factory does it. Trust me.
