I think I have a ticking coming from my timing chain. Its an 05 base coupe with 86,000 mi. Is there a recommended service and how do I do it?

First, figure out where the noise is coming from it could also be the other chain. Changing the tensionner is not a bad idea though.

That sure sounds like timing chain is flopping around. Don't wait until it jumps a cog. If your not sure about doing this, take it to your friendly neighbourhood mechanic. This would be a good preventive maintenance. Check if you have the new version of chain tensioner or still have the old. New one has a bump in the middle of the bolt head.

Nothing if you do it yourself, maybe $50 at a shop plus purchase price of the tensioner.

Looks like it's time to change that tensioner. An ounce of prevention is worth a pound of cure.

I just removed the valve cover, tie-wrapped chain to both cam sprocket, then removed old tensioner and installed new one. Tapped the guide from inside the head to release the tensioner and cut the ties and re-installed the valve cover. It cured my initial morning start noise and I sleep better when my daughters take the car.

I'm having a tough time visualizing it since I've never seen inside a valve cover before. Would I need a new gasket?

What do you mean by tapping the guide? Tapping the tip of the new tensioner?

Will my oil filter socket work? The head of the tensioner looks kind of shallow

No you can salvage the gasket, it's just rubber.

And yes you tap the guide that leans on the tensioner to release it. I just used a long flat blade screw driver.

The oil cap socket is perfect for this job.

Once I open the cover I'm hoping it's pretty obvious what part you mean to tap. Wise idea to use pb blaster on the head?

Is there a bolt pattern I should follow when tightening the valve cover? Unfortunately I don't have a torque wrench either.

Read carefully, don't touch the chain it says what I told you. reach diagonally to the guide and push,tap, jolt whatever. You will feel it releasing and tightening the chain.

You will figure it all out once you see how it's made in there. No rocket science.
