It appears my oil guide housing is leaking (2008 Cayenne TT).  From reading others' experiences, it is a painful repair.  It appears to leak more when the car has been sitting; if driven daily, the leak appears minimal.

 

Are there any strategies that have worked besides dropping the subframe and resealing it?  There were comments of poor bolt choice for 08 and possibly other years - might bolt tightening or replacement help?

 

I may try a different oil weight; currently using Mobil OW-40.

 

Any advice would be greatly appreciated!  Pretty frustrated with this one.

Generally tightening (torque evenly) the bolts can either reduce or stop leaks or make it worse, bit of a gamble. 

You could try a thicker oil depending on your climate? Most climates don't need a 0w oil. 15w40 can work in warmer climates, even a 10w40 is fine down to -10 or lower. 

These stop leak products are not advisable IMHO. Unless the car isn't a "keeper". 

You may be putting off the inevitable mate, need to be dropped and resealed properly?

It may be inevitable, just hoping to reduce the leak a bit.  Slightly thicker oil is something I will try.

 

Anyone had success tightening the bolts? 

 

Or anyone had success doing this repair without a lift?
