But there have been LOTS of examples where it didn't come apart and did indeed keep the oil contained. Just like a roll bar won't save everyone one from every wreck, but it doesn't mean they don't help often times. I had a buddy that killed a 440. Windowed the block /killed the pan. Not one drop off oil under the tires. Diaper stayed together.

The diaper has a big depends pad in it to absorb any fluid that spills. The hole for the oil level is a plastic window that is sealed. The drag link holes are open and there is a chance that fluid may escape from that location if the block or pan is windowed in that area, but a majority of the block/pan is covered and the hole is high enough to contain the contents of the pan/block. Some people run a bellows on the drag link that seals to the diaper, but I have not explored that option. 2012 422 Allstars NSS Champion 2013 422 Allstars NSS Champion 2014 422 Allstars NSS Champion

I built it big enough to go from in front of the damper to behind the bell housing area. It goes outside rail to outside rail, sides match the contour of the frame rails and it goes around the lower control arms. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Two to the front header bolts, but the rear two were too close to the tubes, so I drilled and tapped the flange between 6&8 and 5&7 to use studs so the bracket can be pulled up and slipped over the stud. To change the oil I have to drop the drag link (I use the bushings from Mike Roth so it slips off easily) and drop the back of the diaper. It's a pain, but DRE didn't want to put a flap in the bottom for fear it may leak. Having the diaper on and off about 40 times over the years; you learn a few tricks to make it easier. Also, we never start a fresh engine with the diaper on to check for leaks, so the drag link comes off again. The bushings are the cats meow. So that is a DRE diaper...Do you have to send them the pan I am assuming?

They will make the diaper anyway you want it
