Photo #11. To remove the holding sleeve just use some standard pliers and squeeze the holding clamp so that it can be pulled out. I then sprayed degreaser down the drain tube to make sure nothing was blocking it. After it drained I blew air though it for a while to completely evaporate the degreaser.

Photo #12 Here is the new check valve and holding sleeve installed. To install it. The nipple on the check valve MUST BE DOWN. While holding the clamping sleeve with your pliers place the check valve on the sleeve with the check valve nipple down. Position the combination in the hole and press it in. The clamping sleeve has a beveled edge and a non beveled edge. I placed the beveled edge at the top to assist in inserting the sleeve. I could only get the sleeve started using the pliers. I then drove the combination all the way using the brass punch and the hammer. Tap it lightly this is not a wheel bearing or such. You will know when it is seated by the change in sound while tapping as well as it not moving any further. Note the amount of exposed sleeve in the pictures.

Photo # 13. All the parts have been cleaned and are gathered together to reassemble. Notice the new oil pan gasket. Make sure you completely remove all of the old gasket from the matting surface. Photo # 12 shows the clean surface of the upper oil pan.

Photo # 14. The completely assembled oil pan with new gasket and check valve. I now have to degrease and pressure wash the engine and under carriage. This leak has made a mess.

Photo # 15. My personal reward.

I will let everyone know how the repair has gone and let you know if the has solved the problem.
