1G Engine oil on slave cylinder

[AWD-Tony]

After I drive the car, there’s ENGINE oil on my slave cylinder. I don’t/can’t see where it’s coming from. The turbo oil feed from the head is blocked off and not leaking so I assume it’s coming from here.

Just want to know if anyone has experienced this leak. I did not check this after I got it back from the machine shop.

So you didn’t install the plug yourself? ( no judgement, just confirming) definitely seems like it should have sealant. Also, as I recall from browsing parts pages, the threads on these plugs are similar to but not the same as npt. A shop might make that mixup.

I would think if oil could seep down from there onto the slave, it might could also get into the clutch, which would be more than a nuisance. But maybe not. That’s not the easiest location to investigate when everything is in the car ( though these cars that’s more often the case than not).

Yeah I did not double check it which is my fault. There is a possibility that oil could get on the back of the flywheel wheel but not the clutch unless it gets out of control. The starter plate is between the two so I’m not too worried about that for now at least. Plus the leak isn’t too bad. Doesn’t even drip onto the floor.

What goes here?

The OEM replacement plugs come with thread sealant on them.

I doubt the machine shop put thread sealant. Thanks for the info Brian!

That would explain a small leak, for sure, oil pressure being what it is. Really simple fix, but not necessarily easy with the location.

I know. Have to drop the trans for this
