For years, ipd has been machining used crankshaft housings to accept a more modern and leak resistant silicon seal. In the beginning, used housings seemed to grow on trees. Times have changed since then and now scarcity seems to best describe our current supply of used housings. While aftermarket housings are currently available elsewhere, ipd has found the more modern castings to be of poor quality with threads that can be easily stripped. Ipd only offers OE Volvo housings, precision machined to exacting tolerances for years of reliable leak protection. Fits all B18 and B20 Engines.
