I thought the sides of the adaptor block were just flat, so I don't know how a washer could have gotten embedded in there. It's certainly possible that it's stuck there, but I'd expect it to get caught up in the threads of the banjo bolt so that it would come loose as soon as the bolt was removed. But anything's possible. > Whatever, I got another copper washer. this one was exactly the right > diameter, but slightly thicker than the original, going by Russ's > measurements. I put this in and the leak stopped. If there are actually 2 washers in there now, then this increases the odds of a leak somewhat, since there is now one extra interface, but if it's sealed, it's sealed. One other possible problem might be that if you have 2 washers in there then there is 1 washers thickness less of thread engagement, which makes it somewhat more possible to strip out the threads. > Is there any way to test that the air cooler is working?

It will work unless it is plugged by an out-of- place seal or by internal dirt or bypassed by an oil control piston that is stuck. It can be rendered ineffective by dirt in its fins, or by the lack of the foam "seal" that keeps air from just bypassing the cooler. BTW, this is the oil COOLER, but I suppose you could think of it as an air heater. ;-) -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
