Timing Chain out of Position
Started the car on thursday, rough idle, drove it home, drove it to and from school the next day. still idling rough. Sat in the garage all weekend and just ran the codes. Timing chain out of position and various cylinder misfires showed up. Any help or advice about what to do about the timing chain would be greatly appreciated.

How did you determine the cam(s) are out of position (what diagnostic tool), and what codes did you pull?
Year and model would be helpful.

Meanwhile , start hunting for cam lock tools or making a diy tool.Buy some green cam plugs. Then you'll be ready for the advice others will give -and not tempted to try without the essential cam lock tool.
You should probably ask if it is wise to run the engine with a cam timing issue ? If it has jumped time, it could jump again and that could be very expensive !
There are some great diy tutorials available to re-set the timing but we need to figure out why/if it jumped first. There is quite a list of possible causes - have you done any related work recently- IMSB?, Solenoids?Chain-Guides/pads? I see a 24mm socket in your future.......

Sounds like the chain adjuster is failing. Get some diagnostics on it before you go mechanically inside. If the timing is 25* out, the adjuster has failed. The other possibility is severely worn chain wear pads on the chain adjuster.
This is if its a 5 chain engine.

Have you checked the cam deviation values?

Let me know if you want a hand wrenching on it. I don't mind coming over and helping tear apart a boxster.

Smart move, but I still wish I lived near you so I could try to convince you to let me help you tear it down and fix it as a DIY!

Thanks for your interest! At this point, its worth the money to pay someone to diagnose and fix the problems. If I attempted a DIY, I'd be out of a car for a longgg time as I can only work on it on weekends.
