Hate em! Small leak behind my PS/Vacuum Pump right where the timing cover meets the block (93 in sig). Anyone have a blowup diagram of this area? I've tried Permatex, Seal All, and now JB Weld. It's so small when I have the area all clean (I can virtually see the first drops), but I cannot get the thing to stop. Do I really have to pull the timing gear assembly (which entails removing the cam etc.) to properly stop this thing?


Update: Fixed! Last application of JB weld in just the right placed did it. Engine oil leaking right where the gear case gasket ends on drivers side. My 91 did it on the opposite side couple years ago, so I figured it must be a weak link on these gaskets.

 

Have you been inside your case to tighten the case bolts? Could be where your oil is getting by.

 

I did tighten the ones I could get to when I did the KDP repair, but that didn't seem to help. Seems like the lower drivers side half of the case gasket. It's sooo small but, after time and highway driving, it makes a mess. A blow up schematic of the area might help my blind feeling with my hand. Doing a long trip soon and don't really want to tear into it now, but if I can stem the mess just a little...

 

Is it engine oil or power steering fluid? You have to remove the timing cover and the bolt to the gear housing to remove the pump.
