The oil trap needs maintenance when there is NO vacuum at the oil filler hole or dipstick tube.

The maintenance interval is quite variable and depends on driving habits, type of oil, oil change intervals, turbo or NA, etc. It was worse with the 5 cyl than the 6 cyl.

So long as your system creates a small amount of crankcase vacuum, you are OK. Once the pressure in the crankcase goes positive, you are at risk of pushing out the cam seals or engine seals.

To check for vacuum, remove the oil cap, wrap a latex glove over the filler tube and secure it with a rubber band, and start the engine. If the glove inflates, you have a problem as it should be slowly drawn into the hole.

Keeping it running is better than buying new
