A must for your Toolkit, and cheaper than
a Valve Job! The over-head cam engines in our water-cooled
Porsche's require little more than regular maintenance to provide
outstanding performance.
One thing we do have to watch is the cam belt tension - in an "interference motor" such as ours, the valves must be
lifted up out of the way precisely at the moment the piston comes
up. A cam belt that jumps a tooth or slips will result in bent
valves and a very expensive repair.
Belt Tension is Easily Checked This
is a quality re-make of the original Porsche® tool - and it comes
with instructions that show step-by-step how to check the belt
tension on your 928. Similar instructions are in the workshop
manual for your 944 and 951. A quick check can provide the piece
of mind you are looking for, and help avoid unnecessary and expensive
major engine repair.
