Washing down a Camry engine?

Am I running some sort of risk hosing down my Camry engine after degreasing it?

As long as the engine isn't hothot you should be fine. If you go to a commercial car wash place, let the engine cool 5-10 minutes first before hitting it with the water lance. Try to avoid directing it at the distributor, the wiring harnesses, connectors, and fuse boxes.
