well when i spun my bearings on my D16z6. I opened the filler cap. And there was like oil vapor/steam coming out of it. You think i might have to replace the rings on the pistons?


Not necessarily. At operating tempature, there will usually be some steam/vapor coming out from your oil filler cap hole when you pull the cap. Perform a compression test or leakdown test to see if you need new rings.
