OK first off its not the famous 4g63 tick trust me.

i started to here this slight tick i thought nothing of it since the 4g always ticks but then it started to get worse really bad almost like a rod knock. at idle its fine but then at like 3k its really load. i was thinking camshaft broke or worn, rod knock, skipped timing, bent valve, i don't know. also when i try and drive it it some times just dies out of know where in the middle of a turn and its really laggy i have to slam the peddle to the floor for it to go anywhere crazy help me out.

 

did you get a check engine light? try to pull some codes with a scan tool or something

 

yea thats what i was going to do it come on then went off

 

help me out guys

 

check engine light came on and it was the o2?

i took off the valve cover and there is no visible damage

any ideas

 

Sounds like to me it's a rod bearing going bad does your motor burn oil and did you drive it when it was low on oil?

 

i was thinking that to but it sounds like its coming from the top end more then the bottom. and i had some work done at the shop i never take my car to shops but i did this time and i got it back with 1qt low?

 

If the sound is coming from the top it might be a rocker from the cams are you sure it coming from the top not from the bottom because the sound and rpm you mentioned is usally the symptom of a rod bearing lso one quart low wouldn't cause a problem unless your abusing the **** out of it.How many miles on the motor.boost setting,mods and is it the mivec motor?

 

i think its coming from the top.

i haven't really abused the car. there's 43k on the motor boost is 25, just basic bolt on's for mods nothing crazy and its not a mivec motor.

 

thanks for the help everyone it was a worn cam.

 

runs like a champ now
