So I am trying to Remove valve cover on my wife's 2008 HHR SS 2.0 Turbo. There is a line on the back passenger side of the vavle cover. It looks like those quick connects on a fuel line except there is no room for the special tool to go into it. How do you go about removing this line? I get to change the timing chain over the christmas holidays. Also if someone has a list of torque for all bolts involved in timing chain and balance chain replacement.

Remove the line at the turbo. It's a 10mm socket head bolt (if I remember correctly). The end of that hose has an o ring. Wiggle and pull out.

You do not remove that line from the valve cover

I removed 10mm bolt on turbo and have been wigglying and pulling but it is not coming out. Sure I am not missing something?

It will come out.
Use WD40 on the area and a small pry bar.
Take an old flat head screwdriver and bend the tip 90* to make it.
P.S. Don't worry about torque values with this small of a bolt.
Murphy's Law. If you broke it, you tightened it too much.
When you tightened it back up, make it wrist tight, and you'll be OK.

Yup the wd40 did the trick. Wow that o-ring is old and HARD. thanks

I bought the cam sprocket bolts since the are TTY. Based on rock Auto they are Cloyes 9-5496. I can assure you this is incorrect, those bolts are short, mine are about 3-4inches long. Anyone know a part number for camshaft sprocket bolts for a 2008 SS 2.0 Turbo? I checked Cloyes website and it does not even look like they make them for VVT.

Most people reuse the OEM bolts , 11588844 which are discontinued

Well Holy Mother of God!! I got the timing chain changed out on me wife's SS. Not an incredibly difficult job, but this was my first go at it and I think it took about 9 hours over the course of two days. Above all else, I know it is done correctly. Everything has been properly torqued. I ended up going to the dealership and buying a crank-damper bolt and two camshaft - gear bolts, about $5 each. Those damn TTY bolts, I aint taking a chance in snapping one of those by reusing it. I bought timing cover gasket felpro TCS46079 $21, Timing chain kit cloyes 9-4201SA $101, Balance Shaft Chain kit Cloyes 9-4202S $99, Cam cover felpro gasket $26 and a new belt. So about $300 worth parts! Cloyes has a lifetime guarantee. And the original plastic chain guides are stamped cloyes. When I do it again, I think I can do it in half the time. I spent an hour trying to disconnect the valve cover hose from the turbo (Thanks Cat Man HHR). I also removed the old timing chain tensioner and had to go look up a youtube video explaining how to reset it. I absolutely had to understand how this thing worked. After all this work and then they say whack it with a screwdriver to actuate it, aint good enough for me! BTW before removing the chain,we turned the crank several times to get top dead center and all chain links to align, I noticed that the engine crank sprocket had skipped one link, that was a close call.

Root Cause analysis - The black plastic timing chain guide had broken where the top bolt goes thru it. This could have destroyed the engine and probably has destroyed thousands already! What a piss poor material to make something so important out of on an interference engine. I know that we use plastic guides to prevent noise, I guess Delrin would have been to costly.

I repaired cars where parts wore in a short life time that shouldn't have.
Back in those days the term was "Planned obsolescent" from the manufacturer.
Built it cheap and sell it high. Make that profit.
