On another note, how mush tension should the oil pump chain have?

Correction. "Why too much silicone shouldn't be used"

The chain shouldn't be overly tight tbh, but it's not loose if you understand me?

I will concede your correction
My chain feels fairly loose tbh. Around 12mm of slack

I found this in my old exclusive engine

factory fit half the time. Every single one has the white/beige stuff in the strainer. That's had a fair bit more than necessary used though

12mm movement on the oil pump chain okay before I pop another sump on?
