2011 hhr 2.2 80000 miles put it in the shop for engine noise so far they have found 1 missing and 2 broken chain guides been using 5w30 napa full synthetic oil change 6000 miles they dropped the oil pan looking for the missing guide parts.

 

Oftentimes, it is the bolt for the guide that goes first. There is an upgraded bolt available. Rockauto, ZZP, many other sources.

 

Timing chain has the front guide , the one that breaks at the top bolt, and the tensioner guide.
I use the Cloyes kits
9-4201SA timing chain kit, you don’t need to change the VVT gears in the cam shafts
9-4202S. Balance shaft chain kit
and the Melling 5499GMB front tensioner upper bolt replacement bolt

 

I got the napa timing kits its what the shop who is doing the work for me asked for.both kits and Valve / timing cover gsk.came to $248.

 

Get the bolt too. You don't have to delay the job for it, it can easily be replaced later.

 

And are they replacing the crankshaft/harmonic balancer seal?
if they want to be through, use the AC Delco seal , I’ve had Felpro and a Durlast seal fail after a year or so.
Are they replacing the camshaft and the crankshaft bolts? GM recommends they be replaced.

This explains the upper front guide bolt issue

 

Got my car fixed the misding guide was in the oil pan labor cost $757.85 including tax Patts $248.00

 

It’s fixed, enjoy the ride! Keep it clean and drive it often!

 

Thanks we plan to

 

Inquiring minds want to know. Did you get the upgraded bolt mentioned above ? Or do you plan to get it ?
