Got the old front diff cover pulled,
drained off smelly fluid, no water in it, looked ok,
Inspected gears, ok,
Check magnet, nothing much, no worries,
Mounted my new BTF diff cover with Black RTV.
Waited 2 hours,,,, drinking coofee and gave my both front seats a Good Meguiars 2 step threatment.
RTV seemed quite dry by now, refilled with Redline 75W-140, got about 1.7-1.8qts in it with the new BTF cover,
and i noticed the filler Hole sits about 1/2" higher than the stock.
Drove 2 km home, recheck, no leak
