Oil fill and pressure check, it all went great.
Rick, thanks for the oil filter info, first start will use the 51061 filter without drainback. That's ok because it will get oil system primed before startup and I have 51060 filters with drainback for further changes. The 51061 will only be used at first 20 min run.
I used a 40 psi gauge I had in the drawer, it would be fine for indicating if there was oil pressure build or not. I prefilled filter and as soon as it fully filled, I got immediate oil pressure that pegged the gauge.
I didn't run the drill at full speed to allow air to work out of any passages but had no problem getting oil up to each rocker. Naturally the rear rockers got oil first , followed by others towards the front. Both sides oiled almost simultaneously. I've primed engines before and this one "felt" really good on how quickly and thoroughly oil was supplied.
I rotated the engine several times during the process to be sure everything shifted around for oiling. Everything went fine, I'm very happy.
Tentative schedule is within the next couple of weeks to get the engine back into the car. Still lots to do then for the first start.
Edit - one aspect of this engine install is that I won't be driving car for a while after the engine is run. My concern was about the rings seating or at least getting a good jump at seating. I think the roller stuff and bearings will be fine regardless. I contacted Perfect Circle/Mahle to ask what break in oil they recommended for the Plasma Moly rings I installed, related to my delayed driving situation. They recommended a non-synth oil. I asked about Valvoline VR1 10w30 and they said that should work fine. I'll use VR1 again after first start and at first drive. After some drive time I can check leak down and if its ok I'll go then to the QSFS.
This engine/oil pan combo takes 7 qts, including almost a 1 qt filter. I'll drain the pan of the QSFS oil and verify it's about 6 qts. No big deal as I use it in our other vehicles. I go back and forth on whether to just leave the filter alone with QSFS or swap it out for one I fill with VR1. Personally I didn't think the small amount of full synth will affect ring seating, but I don't want to goof it up at this point.
