Question about valves adjastment

I am moving this thread from another forum.

Sorry if you have read it already.

This past weekend I adjusted valves on my son's 95 Accord LX.

The mileage on the car is around 160,000 (speedometer does not work)

A weird thing is that all exhaust valves were within specifications: 0.011 - 0.013.

So only intake side had to be done.

Does it mean something or is it just how things work here?

My daughter in law bought it at 55,000. I doubt somebody did anything to the car before that.

Nobody adjusted their valves!!?

I am surprised!

Thanks, Kenny!

The link you provided takes my back to the same forum. What page did you want me to go to?

Crap, I'm very sorry about that. I meant this page:

It's Honda Society under the 5th Gen Section (94-97 Accords).

I know I should check them but my theory on valve adjustment is if it runs good and I can't hear them, it's all good.

I don't know but I suspect the intake valves may wear more just by virtue of the fact that the exhaust valves have more coolant flow dedicated to their area, so the stems may actually run cooler than the intake valves...and if the motor has any amount of foreward pitch the way it sits under the hood the oil runs away from the intake side, but towards the exhaust side...

just guessing though...

PS was just thinking...the exhaust valves may heat up quicker and come into a zero lash condition faster than the intake side....that would mean less time banging around with a cold lash gap between them...so the intakes probably take more beating over the life of the motor...

Actually that makes more sense than anything else I came up with...I'm going with that...final answer;)

Jeff, I think it is better to have noisy valves then valves too tight. A valve that is too tight will not completely close and will have hot gas leakage causing an errosion of the face and burnt valves. On the other hand, if they are too loose, the cam rocker will slam down on the valve stem and hammer the stem.
