ok, im sick and tired of the clanking noise when i turn on my car, sometimes it goes away and sometimes it doesnt. If i don't adjust my valves and let this go on will it get any worse? will it lead to instanses causing danger to the motor? Has anyone gotten their valves adjusted? if so how much will it run me?
Thanks in advance
Speed kills; get a honda, u'll live forever.
well is there anything i can do about clanking valves? this only happens when the car is cold, and the whole oil not getting to the valves is bullshit. I dont see new cars starting their engines and hearing the valves destroy themselves (its that loud). The moment i start the car i can hear the noise with all doors closed and music playin. It goes away after about 10 min of drivin but even then the engine doesnt sound right (still a little clankin). I have heard people with altimas doin valve adjustements....if not than what can i do?
Even with hydraulic lifters you still have to adjust them.

Everyone who is serious about having a "fast" KA is either FI or N20 equipped.SHAWN is the exception to that though.

WRONG !! We do NOT have Hydraulic lifters ... KA24DE uses a shim type valve adjustment , Cost wise its about $90 to check them , if any need adjustment then it gets expensive .... I would say the average is around $200 ..... But from what is stated , it does sound more like an upper tchain guide noise , Nissan has a bulletin that says to remove both upper chain chain guides ..... I would say have a good shop remove your upper chain guides, then check the valve clearances while the valve cover is off .... If they are close , leave them be , but if any are way off , then you will want to have them done .....

Um, No you dont know what you are talking about , how many KA24DE heads have you had appart ? Believe me , I have done reshims on mine about 10 times , with the TopEnd Performance regrind cams , and a fresh head, you have to reshim alot to get it just perfect !!
They should be done only if noisy or every 60K or so ... they dont wear , so they dont go out of spec very often ......
KA24DE's have no sort of Hydraulic lash adjustment , the SR20DE does ( and even those have a valve adjust procedure ) , but the KA is a full solid lifter engine ...
thats just what i was told by a mechanic, he said both ka and sr20 have hydraulic lifters, guess he didnt know. i dont get much noise when the car is warm but it really rattles when cold. NO its not the timing guide that sound doesnt go away. This sounds like a chain getting pulled over a metal bar, it gets quiter and louder periodicly until it dissapears after tha car has warmed up. Why is it so expensive to adjust the valves?

To replace the shims you have to remove the cams , that takes time .. The adjustment requires you to check the clearance , if its off you replace the shim with a different thickness shim , the shims are like $8 ea. from Nissan , but the cams have to come out to replace them .... I will say if you do have the valves done , remove the guides anyways ... not to much more work after the valve cover is off You noise sounds like the guide issue ... But yea, usualy that gets most noticeable when warm ..
Not trying to hit up all these old threads. But i been searching and reading and they all have to do with each other. Shawn, you said that you should reshim the valves about every 60k or if excessive noise. Well my car is about 115k and i really doubt that they have been re-shimmed. I am planning on taking off those dam tc guides and i am wondering if i should go ahead and check the clearences on the valves. That and is there anything else i should do while i have the valve cover off.
