The owner's manual on my 06 SE Outie calls for adjusting the vlaves at around 30k miles or whenever is necessary. I have had the car for almost 2 years now, and have always changed the oil on a regular basis, 6k miles Mobil 1 Full syn 5w30, and OEM oil filter. (I know this is prob. too frequent) The car is not driven hard, and most of the miles are highway miles.

I pulled the rocker cover and went to check the valves. I found that all of them where within specs. My question is: When does this need to be done? The dealer told me it must be done every 2 years and they charge about 120 for the check. But when I checked them they didnt need it. I have not owned a car that needed this in over 10 years, as most modern cars have hydraulic valve lifters, but the 4G69 dosnt.

Does anyone have a 4G69 with high milege? How often do the valves even need to be checked? If at all?


Thanks in advance!

I have 125000Kms on my MIVEC I think you should just touch the valve train if you ear a valve clicking or an abnormal sound. Mine just recently has started to click when cold but that should be normal for a 125000Kms vehicle and I know it is not dangerous just annoying. I have noticed that if you bring the rev's up over 5000rpm for a few seconds that this clicking disapearses for a few weeks. I don't know why but it works for me. Maybe crude gathers or something.
