I know this has been discussed but I haven't found a definitive answer for the torque requirements of the camshaft oil feed banjo bolts.

I have replaced mine with longer ones and thicker copper sealing washers - bank A I could probably have opened with fingers, wasn't tight at all.

Anyhow I have the new ones in but they're just snugged up - came to look for a torque setting in the repair manual - since I'm posting here you can guess how successful that was.

I've read a few posts about these things and 'just snug enough' with my luck is letting Murphy into the room - if something simple and stupid can mess up my day it absolutely will (would be the year in this case if they strip out).

Does anyone have the official Jaguar numbers for these things ?

I have just consulted the Jaguar Repair Operation Manual. NO torque figures are given for this operation, not even in the detailed description of how to do it, nor in the Torque spec section.
I reckon 15 ft llbs would be plenty, with no real chnace of thread striping with your longer bolts, and I would use some Loctite too. If possible, maybe weld up a convoluted-lever special tool that in extremis you could use, engine in the car, to nip them up? See where the flats of the bolt are and make the tool so you know you can engage it? It is the A bank ne that is the problem, engine in car.

 

Well I've nipped them up, 15ft lbs, if they leak I'll be gutted. I also scoured all the service and repair stuff - even the Google garage - came up empty.

 

Ben,

I've had a look through the facelift manual and found the following for 5.3 engine camshaft oil feed pipes:

Banjo bolt (cylinder block) 32-36 Nm
Banjo bolts (cylinder heads) 23-27 Nm

So, at 17-20 ft lbs on the head, you're not too far off at 15ft lbs

This is from the late model factory workshop manual. Torque figures are in Nm.

I've filed that image away for sure. Thanks. Definitely not in my service books.

 

jal1234,

Those are the torque settings for the banjo bolts relating to the oil cooler, but those are different to the ones that I had quoted for the camshaft oil feed banjo bolts, aren't they?

Paul

 

Oiul cooler comes off the filter housing on mine, those in the image sure look like carnshaft oil feeds to me - you can see the oil cooler lines right at the top of the image. I've gone with 23Nm anyhow. I'm hoping I don't need to pinch them any tighter - even 23NM had me in a sweat ....

 

Ben,

Here's the page from the manual on the cam oil feeds, with the figures that I had quoted

Paul

 

Any chance of it growing a bit - pretty please ... my eyes ain't that good these days

 

The whole page also has the oil cooler on it. I only copied the part with the cam oil feed banjos. Note that there are two different specs, depending on whether its the banjo on the side of the block/oil pressure sender pedestal, or the cam feed banjos.
