How to check hyhunda tuscon 2008 hydrolic tappet manually

They are Hydrolic and need no adjustment if You have noise
then it is time for them to be replaced.

Check the repair manual for the setting in the specifications table in the engine setting. You can also call the dealership and ask the parts department for the proper setting.

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check. These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

ur car uses hydrolic lifters instead of tappets but they sound the same when faulty. most likely a 'sticky' lifter. very expensive to change.

rev engine upto 3500 and hold it for 20 secs or so the hydrolic tappets should then reset...

Let me know if this worked.

Mits are well know for top end noisedue to hydrolic tappets. Note we are talking about a tapping or clicking sound here not a knock. You can try using an engine flush product if the noise is bad and then changing your oil. Follow manufactures instructions on the engine flush product. I have also used Marvel Mystery Oil (available at Walmart and most auto parts houses) with some success on this. Generally if the oil is not changed regularily eventually the tapping noise starts happening. FYI: hydrolic tappet can and do fail but generally the noise is associated with not maintaing oil changes

it depends on the oil your friend used, fords DONT like castrol or duchams.. you are better using the 5w/15 fords own brand as the hydrolic tappets need almost water like oil... its a ford and mazda thing..

First thing to do is change oil and filter. Hopefully it has not done this long and has hard faced the shims. Good luck and have a good day.

the oil has dried in the lifters, because it hasnt been changed regularly, it sounds to me you have to replace the lifters
