Hi all,
I'm looking at buying a private party 2005 V6 Highlander with 125k miles. Two owners with long history of regular maintenance including regular oil changes, fluids, etc. since new. A lot of maintenance at dealers, and some at independents as well as a few oil changes at quick lube places. Everything looked pretty good until I opened the engine oil cap and on the "baffle plate" (sorry it that's not the right word) was a rather thick layer of black hard carbon deposit. It wasn't completely hard and could be dislodged but definitely hard and not slimy sludge. My corolla I eventually sold at 260k didn't have any of this present. Just wondering if this is normal or sign of something concerning.
