Fix for leaking oil pan
IMHO
Most seal failures are user error.
Sone seals need sealer some do not.
Letting the sealer cure properly is very important
Most rtv says to apply, let cure for some amount of time, then install and TORQUE to an amount.
Most people apply and torque and then fill and run it wondering why it's leaking.
I replaced a front timing cover on a 96 318. I did it right and not a drop in 5 + years. I let it sit overnight before refilling the fluids
