My journey into the old Volvo rabbit hole began with purchasing a 1985 240 wagon as an inexpensive daily transport. Over time I began to really appreciate the uncomplicated, robust and high quality engineering put into these cars. I owned a few more over the years and eventually purchased a 1979 242. It unsurprisingly has been very reliable and fun, however, a bit underpowered.
My current plan is to replace the 2.1L 4-cylinder with a later model version of the same engine. In this case a 1994 B230FT 2.3L turbocharged 4-cylinder. I will upgrade the power output and durability of this engine with aftermarket engine management and stronger internals.
Part of this engine build process involves smaller, but important details to achieve my goals. In particular, the oil transfer tube between the engine block and the oil pump. The stock oil tube is adequate but the seals on either end of the tube tend to harden, crack and leak over time.
My solution is to redesign the oil tube with more reliable seals and to solve a secondary problem of interference with the aftermarket crankshaft's main studs. I've iterated several versions and methods of manufacture. Eventually settling on a stock-style tube but with improved clearance, better materials and longer lasting seals.
