Engine cleaning advice needed

[Chad300tdt]

I have my wagon off the road and ready for a series of fairly involved repairs.

The oil pan leaks, the spot where the oil pressure gauge meets the filter housing is crusty and may be leaking (but it may be the gasket behind that housing), and the turbo drain is leaking at the top under the turbo and at the bushing where it enters the oil pan.

My question is this:

What should I use to clean all the crud off. I was considering climbing underneath and spraying everything with Simple Green Degreaser and then wiping it off.

I don't want to risk pressure washing it since I don't want any chance of water getting in the oil pan through the almost non existent grommet at the turbo drain to oil pan intersection.


Any thoughts or advice??
I know this isn't going to make it perfectly clean, but I'm hoping to get it clean enough to see what I'm doing with these oil leak repairs and then take it to pressure wash the remainder of the engine once that stuff is sealed up.
