Volvo B21

Oil leaks at the valve cover, worn piston rings or a tired motor mounting are classic issues on the B21 – the 2.1-litre four-cylinder OHC engine that came with the 240/260 right from the start. The parts differ between the naturally aspirated engine and the turbocharged B21ET/FT, where the oil cooler, among other things, is a separate part to keep an eye on.
