Updated 911 oil pump chain tensioner kit. In 1984, Porsche began using chain tensioners that rely on oil supplied by the engine's oil pump.  These new tensioners do not fail like the older chain tensioners often do. The nice thing is that this kit is a bolt on upgrade for the older engines. This kit includes all hardware and gaskets, a must upgrade for all 911s up to 1983 or 930s. The OEM part number is 930105911912 (interchangeable with 93010591199). This has been a very popular item for us; if you are shopping around, take a look where it says how many of these we've sold and compare to our competitors. We've sent these kits to every continent except Antarctica. 

Comes with a full 1-year, unlimited mileage warranty against defects.

Note: Some early cars require 93010500001 oil line fitting. Also some early cars require 2x 93010551300 tensioner spacers.
