Engine flush?

[Lubener]

I already posted about my new to me 2014 crv with the 2.4; it consumes a lot of oil between changes and I was curious if maybe an engine flush would help with the sticky rings? I’m assuming that’s the issue since I’ve changed the pcv valve. Which flush would work?

A quart every 1k isn't a disaster. I might try the next heavier weight oil. I would stay away from engine flushes. All you need is a chunk of debris breaking loose and plug an oil passage to a bearing.

Just changing the PCV doesn't mean too much witout checking the breather and verifying the PCV lines are clear with sufficient vacuum.
