It appears, despite the r/r recently of my valve cover gasket, Superblue is still having a bit of oil leakage somewheres. I can still once in awhile see smoke wafting from the area of the RF wheel arch while idling after the car has fully warmed up. I have now washed the engine bay are 3x, once with Gunk (a bit of a disaster, as posted earlier), then some Simple Green on the areas where oil build-up was clearly visible, and a 3rd time on those areas with brake cleaner spray. I thought the spotless cleaning would make it easy to see now where oil is coming from, but fresh oil is pretty much clear and if the leak is not that great is seems to be hard to spot on the engine.
Wondering if anyone is aware of any dye (or other substance) on the market that can be put into oil to make leaks more visible. The only other option would be to invest in some Royal Purple oil, although I hate the high $$ cost of that stuff (over 2x the amount of other name brand oils).
