Best to do engine cleaning with the cover up/off, but with engine running so you can back off if the water starts givings you misfires. With a high pressure car wash wand, with high pressure water should clean up zip-sip, get the area behind the power steering reservoir so that later you can check if the seepage there is from oil fills dripping down from the oil fill cap, or if you have seepage from a leaking o-ring on the power steering reservoir.
