Thanks, is it possible to clean the filter/screen on a 1nz? I'll have to clean the oil around it and see if it comes back again or stays clean. I may be in the same boat at the op.

The filter only costs a couple of dollars, but if you remove it you can easily clean it with degreaser. The filter is very fine mesh with a plastic support frame.

And I'm assuming it is accessible to remove once the OCV is removed, or would one need to remove the valve cover?
