I have check engine light and codes P2189 and P2187 on my LR4. I searched and determined that one fix may be to replace the PCV Valve. I went to change the valve and there is a huge rubber gasket squished out the side of the valve cover that is blocking my ability to remove the existing PCV Cap. I could probably pry it out, but think I would have trouble getting the new one in. This engine was a replacement after my original seized from the coolant crossover leak issue. See photo and chunky rubber squished on the PCV. Can I just cut the excess? Any advice is much appreciated. Thank you.
