2008 Tacoma possible oil leak?

I noticed some buildup on the engine below the MAF sensor. Is this anything to be concerned about? I am at about 178k miles. Sorry for the crappy lighting.

 

For me personally, yes I would look for the source of the leak and fix it. Some people like to forego maintenance and just let the truck rot into oblivion though. You do you!

Impossible for us to tell where it's coming from though but it could be the valve cover which isn't a very difficult job if you have ever turned wrenches before.

 

looks like your valve cover. simple job. but make sure to clean up your engine afterwards. spray on some degreaser and pressure wash it off.

 

Valve Cover seepage / leak. I also have it.
Don't lose sleep on it, it isn't a painful process to fix yourself or have a garage to do it.
Or leave it and just clean / fill her up once a while.

 

Is an oil leak something to fix? Yes.

did you do the VCG's yet
