Torque for vacuum pump bolts
I have an oil leak that I was told the vacuum pump, 6422300165. Visual confirmation seems to make sense that's where it's coming from. i have the part but need to know how tight to torque the bolts holding it on. Can anyone provide this or a place to find it?
This is on my 2012 GL350.

Cleaned everything up and it seems to be resolved except a slight leak at the hard piping on the top/front of the engine where the hard pipes come together. Need to figure out if I'm missing a piece or o-ring or if it's just in need of a new o-ring.
I did a new gasket at the oil filter housing. That seems to have solved it but everyone I talked to said it was most likely the diaphragm inside the vacuum pump. Should have tried the gasket first, oh well.
