Škoda OHV is family of aluminium-block OHV engines developed by Škoda in 1964 for 1000MB and with various modifications manufactured for range of models until 2003. All versions were four-cylinders with aluminium block, three-bearing crankshaft and wet liners, which were made in various bores to allow variety of displacements. Until 1987, all engines used iron cast five port cylinder head, after that year, 135 and 136 versions for Škoda Favorit and all subsequent variants used Aluminium eight port head.

For 1987 Favorit, Škoda has made major modifications to 130 engine to meet new emission standards. New engine had bimetallic pistons to lower oil consumption and new 8-port cylinder head, which improved power output and allowed engine to run on unleaded fuel. To fit new cylinder head, engine block had to be modified. In 1993, engine was available with Bosch single-point injection system with catalytic converter. In 1996 engine was further modified to meet EURO2 emission standard, modifications included multipoint injection system, larger camshaft bearings and larger intake/exhaust valves, which further improved power output and efficiency of engine.
In 1999 engine received last major modification. Engine block was reinforced and modified to fit larger 78mm crankshaft, valvetrain and lubrication system was modified to fit hydraulic tappets. As there was no need for distributor (MPI used ignition module mounted to cylinder head), valvetrain cover (in previous engines unchanged since 1964) could be made narrower, moving accessory belt closer to engine, so engine could be fitted to VW Lupo. Injection system was upgraded, now using two lambda probes and drive-by-wire throttle valve. These modifications allowed to meet Euro 4 emission standards, before production ended in 2003
