Timing chain . where is it located and is it a motor tear down to fix?

I assume you're talking about the 2.7L V6. As you're probably aware (having had it apart before), the timing is properly set by aligning the colored links on the primary timing chain with the marks on the crank sprocket and cam sprockets. The only way I know of to see all these at the same time is to remove the timing cover, and you have to tear the engine apart to remove the timing cover.

It is a timing chain and it is located on the front of the engine behind the timing cover. It connects the crankshaft and camshaft. There are sprockets on each shaft that the chain rides on. I find it unlikely that the chain slipped but the only way to know for sure is to check the timing marks. You can usually pick up a manual at most parts stores and that will help identify timing marks as well as some basic diagnostics you can run to help narrow down possible causes.

If the timing belt were broken, the car would not be driving at all. If those codes weren't confused with another symptom it could be the car needs a tune up. You should think of when the last time plugs, wires, air filter were replaced. If they're pretty new, it could mean a cracked cam shaft sprocket has the engine out of time. Honestly, a full tune up would be cheaper than paying a mechanic to tear down and close up the engine. Good luck!

The 22re engine was infamous for having timing chain problems where the timing chain guide and tensioner would rub on the back of the waterpump. Check your timing chain to make sure all components are operating correctly and check the back side of the water pump. If it succeeds in tearing up that water pump cover you will coolant rush into engine and water lock the motor. More damage than checking and or replacing the timing chain and components.

The valve timing marks are inside the timing chain cover. There is a location dot punched into the camshaft and crankshaft timing gears. The two dots face each other when number one cylinder is at top dead center.

I doubt you machine has a timing chain, it will be a belt. To replace a timing chain means just about a full engine tear down. To replace the distributor. Place the engine at TDC and mark the position of the distributor rotor, also line a fixed mark on the old distributor with a position on the engine. Do not turn the engine at all. Remove the old distributor and install the new one aligning the body marks and ensuring that the rotor is pointing in exactly the same position. Once all the wires are back and the cap is replaced it should hardly be necessary to re-time the engine.

You need a pro that has the proper tools, dont try this yourself. 4 chains. no you dont take the motor out. you will need to replace all chains/ guides. Get your wallet out. could run $1500 or more

You may have to tear in, but plan on replaceing EVERYTHING timing chain related.

First make sure timing marks on crank and timing gear are pointing towards each other and in alignment. Next make sure that the camshaft gear pins are pointing down and at 90 degrees to heads. Put chains back on. Thats it. Make sure all the marks are exactly like I wrote or you will be tearing the motor back apart and doing it again.
