That's also a big'n. Had mine blow very close to home about 13-14 years ago. Fixed it on the spot (there but for the grace of God, I had been planning to do it within the next few weeks so already had the supplies) and haven't had a problem there ever since.X2 check oil galley or gallery how ever it is worded check it asp!
@LCnAZ I'm very leery about using a pressure washer on my engine unless you can dial it WAY back and keep all electrical components protected. I like the idea of wetting it down with diluted Dawn though before any cleaning, and I've been looking for a decent steam cleaner I can really get in there with. I need to do some preventative maintenance and it'd be nice to get the bulk of the nasty stuff cleaned up first.
