Hi
I'm in the middle of fixing an oil leak from my filter housing. I've stripped it all down and I'm ready to put it back together with a new oil seal.
However....
My workshop manual says that the torque settings for the filter housing is 45Nm and the housing cap is 25Nm, but on the cap itself it says 15Nm. So now I'm unsure as to how tight the housing itself should be. :(
I don't want to overtighten as that probably caused the leak in the first place. Any advice??
Thanks in advance! :)

I tightened mine to that and all is well!! :y :y :y Any tighter and the light alloy could crack. :'( :'(

The 'O' ring is on the side of the housing, and all you're doing when tightening it is stopping it from vibrating loose. Ever increasing amounts of torque has no effect on the housing's ability to retain its oil. :y

Oil filter casing to cylinder block 45nm
Oil filter cap 15nm. DO NOT use a 3/8" drive in the square hole in the cap, use the external hex.

That is ok to do if you use a torque wrench drive shaft. :D ;)
........and the hex "nut" is about 21.5mm so unless you use an adjustable spanner you have to estimate the torque being applied unless you use the torque wrench drive shaft! ;)

As an Engineer I just dont like the idea of a a steel square drive inside of an aluminium recess, have seen them with cracks radiating from the square hole.

I take your point completely Pete, but if somebody is very careful, using a 3/8ths Torque drive as I suggest it should be ok. ::) ::) ::) :D ;)
As I state in my post above, the hex is about a 21.5mm, neither 21mm or 22mm, so unless you have a socket of 21.5 you either use an adjustable spanner and estimate the torque, or use the torque wrench itself as I do. ;)

Thinking about your comment Andy I must say I agree as on standard cannister oil filters, fitted to most of my previous cars, I NEVER used a oil filter wrench to either take one off or in particul put one on!! :D ;) ;) :y
Good hand tight pressure was always enough to create a seal that viabration never loosened in my experience. ;)

Thanks for all the replies and advice. Its all back together now and it looks like I've cure the oil leak!! The old seal was very brittle and broke when I prised it out, so hopefully thats sorted!!
Many Thanks
Steve :y
