I have a 1998 oldsmobile Achieva LS and the valves are beginning to tick. The mileage on my car is 89,000 the oil is changed every 2,000 to 2,500 miles. I put one quart of synthetic oil to 4 quarts of high mileage oil. My monthly mileage for my job is 1,400 per month. So is there any thing I can do to prolong the use of this car.

If it is in fact your valves ticking, DO NOT USE A THICKER OIL. I have seen many GM motors start ticking when the wrong oil was used. Try this, I have done it many times to fix this problem. Get a bottle of Rislone. The thin stuff that comes in a yellow bottle. Not the black bottle. Mobil 1 5W-30, and a new filter. Warm up your engine and change your oil while it's hot. Add the bottle of Rislone. Drive 2 blocks. Your welcome. The reason this happens is because oil that has a viscosity that is too high (too thick), will not be able to pass through the small passages that fill the lifters. Your car has hydraulic lifters and if they don't get enough oil, tick tick tick tick tick.

i think of the various different posts must be straightforward on you - in spite of everything, little engine ricers positioned 3" cat decrease back exhausts and f@rt can resonators on their rides each and every of the time, and that they don't have sufficient engine to warrant that! bypass onto eBay and seem for pretend BOV's. they are 20-30 greenbacks. some will bolt into the exhaust on an identical time as some are digital. None thoroughly mirror the sound of a real rapid, however the three" civic exhausts do not precisely sound like a muscle vehicle.... And as a observe - my SS/TC is rapid'ed, and that i'm intentionally retaining the BOV as quiet as obtainable. It does not make sense to sell, and it certainly does not make sense to sell once you're actually not packin'....

Not to sure about valve train noise but a possible Valve adjustment may help. I'm not totally sure on what fluid to use to quiet it down any. I've heard good things about lucas products.

sounds like the bottom part is being maintained well...possibly an intake cleaning where they let a cleaner get sucked in by your vacuum into the intake to clean the valves and the chamber would remove any hard carbon deposits

Run a little thicker oil like 20/50 or add a viscosity thickener like STP oil treatment.

What motor do you have in your olds, It's tough to diagonis valve train noise if you don't know if tou have a push-rod motor or an overhead cam motor

A little valve tick won't hurt. If it bothers you a valve adjustment is in order. There are no additives that will help.

you could try getting a higher octane gas in your car and try putting marvel mystery oil in with your gas
