M116 V8 Timing Chain Upper Guide Rail Replacement Kit

Save your V8 regardless of mileage - DO this job if it has not been done in the last 15 years

For all 3.5, 3.8, and 4.2 liter V8 engines from 1969 to 1991 280SE 3.5, 300SEL 3.5, 380SE, 380SEC, 380SEL, 380SL and 420SEL. These THREE are the upper (and easily accessible) plastic guide rails that most often break due to age and heat. When they break they can cause the timing chain to "jump" the sprocket which will allow the pistons to come up and hit and bend the valves or WORSE if it happens at high speed!!!  As seen on Cherry.
