2001 x5 4.4 oil dip stick o ring

[milesz]

Hi All,

I just replaced the timing guides and chains (big job) and had an oil leak (I damaged the upper oil pan gasket). I had to replace upper oil pan gasket. A friend of mine help and he took out the dip stick tube. I saw an o ring on the floor but I did not put the o ring on the floor with the o ring from the dip stick tube. Last night I finally got it all back together, add oil and it's leaking. Its coming from the dip stick tube there is no o ring oil.

Any instructions on how to replace this o ring?

Thanks in advance
