Installation Instructions

  1. The 2.7L guide stop block is over-sized and made to trim to fit. This is done for variations in chain size that are made possible due to the stretching of, or installation of, new chains and gears.

  2. The guide stop block installs directly under the main primary tensioner. To install remove the right-hand valve cover (viewing from rear of engine) and tensioner, Keep pressure on the guide to prevent the chain from moving.

  3. Simply remove the two small front head bolts. Bolt the guide stop block to the head using the two new bolts supplied in your kit.

Engine with Stop block

When the tensioner fails the stop block is there to hold enough tension on the pad to keep the chain from slipping off.

Engine Without Stop Block

When the tensioner fails the slack in the chain will cause the timing chain to eventually fall off the gears.
