I notice a week or so ago that when my car hasnt been running for a while that it has a clicking noise coming from what sounds like the motor. Its a Blacktop sr20det. After my car has been idleing for maybe 1 minute it goes away. Any ideas on what it might be? Sound kinda sounds like its coming from the head.

 

my KA makes a clicking noise and it is the lifters i dont no if it affects the performance i bought it like that

 

kinda sounds like lifters since it goes away. just a guess but mabey your oil isnt getting to the head fast enough. slowly dieing pump? i dunno

 

yea sounds like lifters to me also. you may want to check you oil pressure. consult with your SR manual, it will tell you what range you have to be in etc.

 

it shouldn't affect anything but since the ka is an interference engine (i think) if the lifters stick and are not compressed you could bend a valve.

 

lol was that even close about the bad pump guess? im more book smart and dont have much "hands on" experience except from shop class and my car. id kinda like to know if i was somewhat right.

 

it is probably your lifters as mentioned, basically when you let your car sit for an extended period of time they flatten out, sag, a tiny bit. once the car/oil is warmed up the sound should go away.

 

sag?

don't you mean that the lifters don't retain the oil anymore hence the tapping?
