A: The core, depending on what size you purchased, can hold anywhere from .25 to nearly 1 qt of oil on its own. Simply "topping off" may not bring the oil up to level when considering the core's volume.

2. Oil level was adjusted.
Q: Was the oil low after initial start up? Where on the dipstick was it reading?

3. Lines are routed exactly as by the instructions AFAIK
A: Double check the best you can around the crash beam and into the wheel well. That bit of the routing was tight. If a line is kinked, it may cause a pressure issue.

4. There are no leaks.

Cheers mate, appreciate you taking the time.
