Crankshaft front seal replacement on N52
The [front] crankshaft seal seems to be leaking on my '06 530i with 130K miles. After wiping everything clean, after couple of weeks of driving, I see oil on the front portion of the lower pan and on the bottom of the pan.
I don't believe the full flow body (oil filter housing) gasket is leaking. I've looked very closely with a flashlight. Everything above crank pulley is very dry.
Valve cover gasket is new and I am absolutely positive it's not leaking.
I also don't believe the lower pan gasket is contributing to this oil leak based on what I see on/around the pan gasket.
That leaves me with front main seal. Has anyone replaced front main seal on N52? Amazon and others sell a tools kit for around $130 (with shipping) to replace the seal and the seal is around $30. TIS states that we need to use loctite/glue after inserting the new seal. I am contemplating with DIY or give the car to dealer. Your thoughts please....
