Valve Adjustment

I have a 2000 OBW, 2.5, auto, it has 99k on it and I'm wondering how important is getting the valves adjusted? It runs fine, except for a little pinging under load, even with premium.

It's Important

Get the valves adjusted per the owner's manual recommendation. Otherwise, you might wind up burning some of them. Then you have a costly repair on your hands.

because of the "shims" which maintain valve openings will "tighten up" the valve opening over time...unlike the "screw and nut" method of maintaining valve adjustment for solid lifters which in most cases will loosen the valve clearance

you have the screw type, it's pretty easy check out the end of this thread.

the wear factor on overhead cam engines is generally due to either the valves hammering the seat [tight] or wear on the cam or follower , the part that rides the cam [loose] in general it shouldn't matter if it's shim and bucket or screw.

no idea on the price, i'm sure someone here has had it done.

realize that the dohc is much more labor intensive and requires parts. checking the clearance shouldn't cost any more, adjustment is where the extra labor comes in.

also if the valve cover gaskets are original or just old they may need to be replaced also.

Generally you would have the valve clearance check&adjust done when the timing belt is done. That is a logical time to do it. Yes the '00obw has the set screw type adjustment and is actually easy to do.

Right that '98 would be the dohc, requiring that special fancy tool thingy and an assortment of shims etc, the procedure is on endwrench.com

If the price is right, I'd be willing to do it, but if it isn't, then I'm down with just leaving it be.

strange philosophy if you read the whole thread but .......

how many miles on the car ?

has the timing belt been done ?

why i said it's strange is, like was said earlier, if the valves are run out of adjustment for too long it will damage either the valve or seat and that turns a relatively inexpensive adjustment in to a very expensive valve job.

if the timing belt has yet to be done, most shops will check the clearances for free or a very small charge since you are getting the other work done.

if it has a lot of miles on it and it's never been done and the timing belt was replaced, it should be checked.

if you have decent mech skills and a 10 mm wrench and a set of feeler gauges, the cost is a little of your time to check them. then you can make an educated choice of whether you want to pay someone to adjust it or to drive it until it breaks.
