This is a pretty tough timing belt job to do if you have never done one before. There is also a kit of tools that are essential to getting the timing right on this engine. The cams are numbered 1-2-3-4 from left to right if you are facing the cam sprockets. If the tensioner was broken and the engine came out of time you are probably looking at at least a few bent valves. Could be time well spent to perform a leakdown test before you spend too much time on installing a timing belt.

Valve slash and clearance adjustments should only be performed by certified mechanics and is not a job for the garage or novice hands on type.
If you still decide to proceed, I suggest you get your hands on a maintenance manual which will list the procedure step by step, including proper torque values.

Hello DTC P0341 & P0133 very common saturn Codes.You need to check condition of Plugs & wires,If not New Replace All Plugs & Wires,also I would replace the #1#4 Coil for the P0341.For the P0133 Reaplce your front O2 sensor with an OEM sensor,not an aftermarket.

SOURCE: changed timing chain and need to align to cam with the crang

Align the chain with the colored links on the chain over the marks on the cams.Twin cams Have a small hole on the cam gears that will align with a hole in the front of head.Crank Gear has a pip mark that goes straight up.colored links on crank go to the 5 & 7 Oclock position on the lower crank gear with pip mark on crank gear at 12:00.Hope this helps
