Outer Limits 4x4 Board

Ey guys i have found a oil leak underneth the alternator on my sd33 had a look under and cant see exactly where its leaking from but its not leaking from the block and its not leaking from above the alternator just from under it and leaking onto the engine mounts, my oil pressure is ok untill i get up to about 60km 70km and then it starts to drop nearly to 0 any help would be great guys
cheers benny

I'm no SD33 guru, But I would take a guess that your leak is from
the vacuum pump on the rear of the alternator.
Age & klms chew the seal and / or alt shaft. Can result in leaking into
alternator.
get it sorted before it kills the ALT.
cheers

Also quickly get a accurate test guage on it to confirm if pressure drop is correct?
