I'm referring to the nut that has the Allen head screw in the middle. The one used for lash adjustment. I had monkied around with that two years ago, and now it's leaking quite a bit of fluid.

 

Yes, It's a washer with rubber insert formed in it.....

 

Thanks. Any idea where one would find that?

 

Remove it then take it to your local auto parts supplier, some foreign cars use a washer such as that on the caliper banjo bolts. If for some reason you can't find one with the rubber, you can try a brass or aluminum "crush" washer that size.....

 

looks like a washer from an ac line fitting at the compressor

 

You can get a seal kit from Napa

 

It's more like an oil drain plug washer. You can prolly find one of those that will fix it without having to buy the whole paper-&-rubber set.

 

I just removed the nut and nothing was under it. That's peculiar because it just started leaking a few days ago and I've never removed it. Only loosened once. A few years ago

 

Looks like good ol' Teflon tape around the shaft screw worked. According to the parts list, there is no gasketed washer on the factory unit. I think there was a seal on the nut, but since I made adjustments I probably pooched it. Anyway, seems to be working now.
