Cycle oil leak

In general, oil travels down and back. Oil leaks can be relatively easy to locate, but I've had two that were very hard to find the source of on both my Mopars. I ended up buying some florescent leak detection dye and a black light flashlight from Amazon.


I was surprised when the leak was not in the area I thought it was coming from. Without the tell tale luminescence leading me forward of where I was suspecting, I never would have found it unaided.

If it is found to be leaking between your cases, it will have to come apart. Then using emery cloth and a flat piece of glass. make sure both sides are dead flat. Then clean everything and reassemble using Permatex Ultra Seal. Make sure you massage it into the metal well.

Are you using a torque wrench to tighten your case bolts? Another location oil can get out is from under the bolt heads that hold the case together. You may be able to remove one at a time, check and dress any burrs, clean the face of the bottom of the bolt head and it's matching seat on the case and put a dab of sealant there. I had oil pan bolts leak at that spot until I pulled them and sealed them.

Good luck.
