What is the recommended mileage i should change my cam belt on my 2002 honda civic type R?

I would change the timing belt approximately every 80,000 mi. This is a guideline only that I have used on my 1979 Honda, and it still seems to be the right mileage for changing the timing belt on newer Hondas such as yours.

its best to change cam and crack sensors at the same time, but as for removing engine to change belts thats a no there is a plate in the wheel arch that needs removing to gain access. removing the wheel and you will see the plate that needs removing. belt change is not hard to do. if the cam sensor has failed and replaced and still a fault then its not this at all that is the problem. you can get a false code, and resetting it and running engine to see if it comes up again. also if the garage is using the right equipment it will be able to diagnose a run test this will tell you the full state of the problem so you don't waste money replacing every single part. a failed Maf sensor on some models can make a cam sensor fail as its linked, and that usually just needs a clean with MAF cleaner, this people change the air filter and forget about the sensor. the muck ats on the air filter can get thought to the sensor and give a false reading. also when a part is replaced the ecu needs to be reset or it will say engine faults any were up 60 starts of the engine. so i would have this done. hope this helps. plus if belts lose you would know while running the engine it will squil or make strange sounds. i would recommend another garage if you are going to this one. use a recommended garage, or a garage specialised to you vehicle. changing parts as they think will cost you more money in the long run. good luck with your repair.

The service book will tell you the answer you want but if you havent got it then its between 50,000 and 70.000 miles ..

It's actaully a timing belt, not a chain. But the mileage recommendation i believe is 60,000 or 90,000 miles.

Not at all unusual for the timing belt to break and cause major mechanical problems inside of your engine. A failed timing belt can totally destroy your engine due to the extremely close clearences. That's why the strongly recommend a preventative replacement of the timing belts in all Hondas and Toyotas at specified mileage frequencies between 70,000 and 120,000 miles. Change the timing belt before it destroys the engine. You may now be at a point where only the Honda Dealer or authorized garage may be able to help diagnose the problem.

With Vtech motors, if the timing belt jumps to much yes you will get valve/piston damage. This type of damage is usually very noticable (knocking, loud head noise, no start) Best thing to do if no damage is noticed have the belt adjusted back into timing. jumping one rib maybe 2 might not have enough to cause damage my prelude jumped and didn't have a problem

If you have never changed a cambelt (timing belt) then it is not recommended that you attempt it. It is a job for a mechanic, as getting the cam timing wrong on reassembly is easy to do and can have disastrous consequences. It is easy enough once you know how, and if you are reasonably mechanically able, I'd suggest getting a repair manual for your vehicle that has a step by step procedure for timing belt replacement. Companies like Haynes produce very good repair manuals.

90000 Miles on the Timing Belt. Do not let this go! A timing belt failure can cause internal engine problems.

Should cost around 200 or so, depending upon your local labor rates.

Good Luck!
