banjo housing drips oil
My banjo housing drips a small amount of oil even when not used for awhile. I have removed and sealed all the bolts ,and they are the proper type for this installation. I removed all the oil and checked the housing for cracks, but could not find any. Is there a colored fluid that I could use to find the crack ,? Or is there an additive to the oil that might take up the gap. This is more of a nuisance than a problem, unless there is a crack that could progress, then a banjo change would be needed, a bigger job that I want to take on right now. This small amount of oil loss has not changed in the last 2000 miles.

Re: banjo housing drips oil
If you have removed all the oil.........tray a quart of acetone or alcohol. if there is a leak you'll see it fast. After locating the spot its a matter of choosing the best way to plug it up.
Just remember to re-install the lube before testing. |

Re: banjo housing drips oil
Mine had a small persistent leak similar to what you describe.
I tried sealing all the bolts with Permatex#2 but that didn't stop it from leaking. I was doing some brake work anyway so I separated the left axle housing and found just fragments of gasket material. I cleaned it up and used "The Right Stuff" gasket maker and no more leaks... It's a big job just for a drip, but if you happen to take it apart for another reason it's not too bad...

Your A is merely marking its spot!

Re: banjo housing drips oil
I have one that does the same. I suspect the PO chased the bolt holes with an ordinary tap.

Re: banjo housing drips oil
Ours leaves a little oil to. Check, it might be coming back from the transmission or rear main. Also mixing STP with the 600 w oil could help. I have heard some folks use 50/50, some say straight STP. We use 50/50. The last 600w oil I purchased from Mac's looks and feels like STP. Enjoy.

Re: banjo housing drips oil
Mine had a seep not a leak. Clean it very well and give it several coats of rustolum. Rustolum is an oil base paint. Dry as a bone

Re: banjo housing drips oil
I had a persistent slow leak from the bolt area in a 7 tooth steering column. I used 600W oil and tried to seal the bolts well with Permatex sealer - twice. Nothing worked. I then had an idea of using some heavy cotton thread and wrapping it around many times just under the bolts heads. It worked great to stop the leak! I am thinking of doing the same things on at least the lower bolts of the differential when I get to it.

Re: banjo housing drips oil
We've had good success with the Permatex thread sealer with PTFE on the bolt threads and heads

Re: banjo housing drips oil
Don't use straight STP, it is not a lubricant.
