Hello! I just replaced the PCV valves on my 2011 LR4, a job that was definitely needed (both diaphragms were torn). Unfortunately, when taking the old valves off, one of the tabs on each of the valve covers broke.

5 tabs on each of the two covers remain intact and I was able to clip the new valves in fine. Do I have to replace the entire cover or am I OK to drive?

 

Positive Crankcase Ventilation. and you may have a leak.
Personally, I’d get a solution in place.
