I'm still trying to chase down this oil leak on my Accord. I had it up on ramps, poking around with a flashlight and saw this. The area I'm referring to is that spiderweb looking "cracking" right above the oil filter mounting area (you can see the oil pooling up right below it). Is this in fact cracking or is it just cheap aluminum casting? Is this a removable part or is the the engine block? What's the possibility of this being cracks, causing the oil leak? I see no oil seepage from that spiderwebbing though. What would this repair entail,if in fact it does need repairing?
