Just got off phone with mechanic that installed engine. For the PVC, he said there should be a breathing baffle there, but I need to check on this.
Here is some more info, he told me this when I picked up the car, but I didn’t remember the details:
When the engine was first started, it had decent oil pressure (60-65psi). He locked down timing and kept RPM at 2000, seemed like everything was doing ok. Once everything was warm oil pressure stabilized at 50 PSI. Engine sounded fine.
He took it for a ride after 20+ min break-in, and oil pressure went up to 55-60psi @ 3500 RPMs. As soon as he let of throttle, oil pressure tanked down to 0. He was right by the shop, and coasted back.
He let engine cool down, pulled release spring out, and put in a stronger spring w/ correct seal. Started car back up, oil pressure was at 100 psi. As it warmed up, the oil pressure started to drop down to 80, then 60, then 40 when engine was idling and warmed up.
He said this was just a patch, and needed to be addressed. When I took the car, oil pressure was around 80-90 w/ throttle down, but then was dropping down to 35 PSI on deceleration.
