1. I have new rebuilt engine done less than 300miles
2. I lifted car way up and look after filling oil and i know exactly where oil is coming from. I can see 2-3 min after pouring oils to engine how its start to leak. I can took video if you want

3. I put it 25nm with special tool (new plug & seal ring) leaks badly.
4. Then i put copper washer and turned it pretty tight i say something like 70nm and it holds almost =)
