Anybody wondering what different types of lubrication have on torque values have a look at this basic explanation

It does not matter whether the torque is 10lbs ft or 1000lbs ft, the true torque value will be affected. There is a reason why so many people strip the thread in their sumps or crack the sump.When people put the sump bolt back in, even if they have cleaned the thread on the bolt, there is still oil on the thread in the sump.

That's strange because there's another guide I've posted on here before that says engine oil is one of the few things that won't affect torque settings?


That aside I still think the main reason is just over tightening from being a bit over zealous due to people not being able to use a standard torque wrench on that bolt.


The wall of the sump plate is much longer than i realised after searching for a photo, and it shows that every thread of the OEM bolt gets used up.
Kind of strange why the newer magnetic ones were made half the size, and explains why they strip the fine threads too.


It does also explain that if a new OEM bolt was used it could highly likely solve the leaking as the deeper threads may still be intact.
