if there's air in the cyl, wouldn't that keep postive pressure, opposite of sucking oil up thru the rings?
I'll have to take your word for it. I have a nice bore scope but I'm not going to pull fresh plugs just to look at the cyl haha. honestly I think they would look fine thou, I ha oem plugs in mine when I got it at 135k of active afm, also the hybrids run in 4cyl mode much more often because of the electric assist. it doesn't need to switch to v8 to get moving. especially interstate cruise, it can handle the small elevation changes by battery not switching out of 4cyl. from the settings I see in hp tuners under dod, looks to be limited mostly by time to oil foaming. but anyways, point being all 8 plugs looked the same, no extra white crude on the afm cyl from burning extra oil.
the windage tray has a nice cut out right at the bypass valve.
to be fair, I alway thought the bypass valve sprayed oil straight up out of the hole on the top on the back cyl wall. but this Pic it looks like there's some holes around the bottom. so I don't know for sure. so eh? my truck has a crazy high oil pressure variable displacement pump. like 60 plus almost all the time. so I have a feeling it's bypassing constantly, especially with afm turned off. no sign of choked up rings or low compression to me.
I mean I get it, it's a junk system. but the details just feel off to me.
