You need to have the right seals in there, or it will leak, or restrict the oil flow. There are 2 different oil coolers, and 2 different cases. The early coolers and cases had 8mm oil passages, and the late coolers and cases have 10mm passages. Early cooler and case takes the thick seals and the thick spacers. Later coolers and cases take the thin seals and NO spacers. If you have a mix of case and cooler, then you need the adapter seals. Last of these that I saw were green. To tell if you have a late oil cooler, is there a part number stamped into the cooler near the oil sender. This is the late cooler with 10mm passages. If there are no number stamped there, then you have an early cooler. The case is harder to determine, but generally, if it has 2 oil pressure relief valves, it is a late case. -- Russ Wolfe '66 FB MT '71 FB AT '65 Bug (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
