How to do timing chain and guides replacement?
The procedure assumes that the transmission, clutch, flywheel, upper intake manifold and other small parts (coilpack, TB, airbox …) have been removed from the car and that other steps necessary to remove these have also been performed (front end of car raised, battery disconnected, etc).
What is the tensioner on a VR6 timing chain?
Each timing chain has a guide rail (curved on the upper chain, straight on the lower chain) and tensioner rail to keep them tight. The lower tensioner rail is a one-piece, spring-driven unit, while the upper tensioner is a two-piece design consisting of a tensioner rail and a separate tensioner bolt.
Where can I get 12 point timing chain?
If you need triple square bits (like Torx bits but with 12 points instead of 6 – also called serrated or 12-point bits) in order to remove things like a flywheel or axle bolts, you can buy K-D bits from your local Napa Auto Parts store (can also buy them on-line).
What kind of noise does timing chain make?
This sound has been described most often as “marbles in a can” or like a sewing machine (see below for sound clip of noise). When the timing chain parts are in good working order, the chains are under considerable tension and NOTHING should be loose enough to rattle.

Can a bent timing chain guide bolt be replaced?
Replace bent, broken, or stripped timing chain upper guide bolt on 2.2L and 2.4L Ecotec. Replaced bent and stripped guide bolt in my 2.2L Ecotec engine. Perfect fit and works as advertised.
Where can I buy a Dorman timing chain guide bolt?
Bought this to replace the known failure of a timing chain fixed guide bolt on the top through the plug in the head. Fit right in. 6000 miles later no issues. This will fit the 2.2 ecotec. Dorman was to correct their application list.
