got the valve cover off..... doing the top timing chain cover gasket and the VC gasket. like to check for good oil flow. what do you look at? what do you poke down what to check for any clogged passages etc. cam lobes look nice and bright save for one that is a bit discolored but no wear signs. any advice will be appreciated!!!!!

Make sure you double check the tightness on the screws holding it down. I cleaned it out with carb cleaner and found the screws were loose before & after and just added a drop of loctite to make sure. Good luck
