What are you torquing to and how much off are we talking? Intake or exhaust? Always same valves?

im following the proper specs. and im not sure if its the same valves that are messing up. I will make sure to note which ones the next time i do an adjustment. which is probably very soon.

How do you know that you need the valves adjusted every six months ?, are they out of adjustment every time you check them at the 6 month interval ?. This does not sound plausible. Your issues are elsewhere.

There are many other things that can cause your symptoms besides valve clearances - MAP sensor, bent valves, burnt valves, spark plugs, coils, injectors........

yeah the valves are too tight when i check them. and like i said, my car drives like brand new once i do get valve adjustment.

and im thinkig it is a bent valve...

subwayasian

and i remember researching about the map sensor. but the map sensor would not make tight valve clearances right?

Are the same valves out-of-spec, each time you check? Could be the adjusting screws or nuts for these rocker arms are stretched or cross-threaded.

Are you tightening the locking bolts separately after adjusting the valve? It is possible for movement to occur during tightening or locking. Do you use the nifty tool that combines the screwdriver with nut tool?

I suspect the problems lies there. Either it is not tight enough and moves on its own or you inadvertently throw it out of adjustment.

From what I've read this happens quite often. Always best to recheck the gap after torquing the locking bolt.

Also, that tool makes a world of a difference. I couldn't imagine doing a valve adjustment without one; especially solo.

Yeah my procedure is using the tool to tighten the jam nut, check clearance. Use a torque wrench to torque to spec, check clearance. If I don't adjust the valve I still torque to spec, check clearance. Do this on all 4 valves then move to the next cylinder.

yeah ive always been using that screwdriver turning thing. the symptoms are getting really bad now. lol. really have to do one but im scared because ive always had some kind of supervision when i did it myself.
