SOURCE: how to replace a timing chain 2000 chevy cavalier

I am familiar with that vehicle but generally with timing chain replacement, the engine needs full access for pulley and cover removal and in some cases the cylinder head requires removal.
Generally timing chains last so that they only need replacement at engine overhaul and it is not an economic proposition to have to replace a chain unless some relative degree of engine work is also required at that time. 

Engine timing chains generally have a tensioner on them which maintains tension, but some chains can wear significantly and cause timing cover to be "ground away" because of "slop".

If the engine is making the noisy rattle of the timing chain against the cover etc, I would schedule a top overhaul (head, machine, test and valve grind) with the chain replacement dependent on mileage with the degree of action.

Some simple simplex timing chains (type of chain similar to motor bike chain) may be replaced without dismantling the engines but I would expect your chain would be a "duplex" dual sprocket type, these are most common. 
These chains are not generally expensive but replacing them can involve a fair amount of work. 

Good Luck and hope this helps, Others will have different ideas.

SOURCE: timing chain noise 2005 cavalier 2.2 ecotec

Just the guide is probably making the noise. So either a new guide or a new chain. I would start with guide first, unless chain looks loose or cruddy

SOURCE: 2004 Cavalier Wiper Motor

hi, im not sure if they would have a separate motor each because most vehicles have a linkage bar that connects the two wipers to keep them in time with each other. without the wipers on, try manually rotating the paasenger side wiper (be gentle) if that moves easily and the drivers side does not even flinch, then it could be a broken linkage. hope i helped!

EGR Code

I had simular problem on 1996 Mercury Marque. Mine was stopped up exhaust port under engine heads = remove heads, clean, replace head gaskets. Also possible that you have a problem with EGR controls, that is due to bad control or vacuum hose off. What does engine analyzer say? Mine was very confusing, listed all kinds of EGR control faults.
Thanks and Good Luck,

1993 accord has dead cylinder

I have seen many of those years Accords with a burnt intake valve, from too much EGR gas entering only one cylinder, overheating and eventually burning and breaking that valve. This causes the valve to not be able to seal the combustion chamber, resulting in no compression and no power from that cylinder. You will have to remove the head and change out the broken valve. When done replacing the valve, clean out the EGR ports in the intake or the valve will be damaged once soon. Those blocked EGR passages are what cause the burnt valve problem in the first place.

2005 Grand Caravan bad EGR

The second Code 404 is for a problem in the same area. It is about the performance of the EGR valve circuit.

Cleaning the ports is a good start. Also checking for a clogged EGR passage beneath any mounting gasket would be a prime place to look.

I deal mostly wth Ford products and this is similar to their problems. Apparently the sensors on both brands are installed downflow of the EGR and triggering sensor. On the Ford products, when airflow through the EGR is measured and found to be weak or non-existent; it blames the EGR and sensor for not opening to provide flow. The actual problem is there is a clogged flow passage. The parts are often fine. You can not have flow at the ending, when you do not have flow to begin with.

So many parts are replaced needlessly because of this misengineered system. Now it is debateable that a sticking EGR could cause the passages to be blocked. It becomes an argument of which causes which in the first place, so you did not hurt anything by replacing the parts. You are just not finished with prepping the area for the repair.

I hope my explanation is helpful.

Changed all the coils and spark plugs but still getting misfire

That is because spark plugs and coils are not the only things that can cause a misfire. Misfires can be caused by all kinds of things including vacuum leaks, burned valves, bad fuel injectors, blown head gaskets, clogged EGR ports, sticking EGR valves, broken valve springs, broken piston rings, fauly coil or injector wiring, etc. etc...
Trying to diagnose a misfire by randomly replacing parts is the EXPENSIVE way to do it...As I see you are finding out....

EGR is dirty. how to clean one? is it best to clean an EGR or replace it?

Is the EGR valve dirty or are the EGR ports clogged? EGR valve failures are EXTREMELY RARE (although the parts retailers sell MILLIONS of them to people who nothing about EGR systems, but are trying to fix EGR codes).
Depending on which engine your RAV4 is equipped with, the intake plenum may have to be removed or partially disassembled to clean the ports out.
As for the valve itself, you can use a little carb cleaner and an old tooth brush to clean the pintle area if it is caked with carbon deposits. If the pintle lifts when vacuum is applied to the valve and the valve holds vacuum, there is no need to replace the valve. This can be tested with a hand-powered vacuum pump with a gauge like a "MightyVac". (see picture)

Egr cooler repalced to get us passed warranty - oil cooler was not replaced prior to 160k warranty exipred- on vacation 2000kms away (only 11000kms after egr cooler fixed) from home towing a trailer...

If the dealer put an egr cooler on and didnt replace oil cooler, it can blow out egr cooler again , restriced oil cooler causes egr cooler to blow out , which in turn can cause overheat and blown headgasket also, if you are seeing white smoke now it is possible for the egr to be blown out again as wel as the oil ooler and/or headgasket
