Bad lifter? Something else?
So today I was driving my car how I normally drive it and I heard this ticking noise. Doesn't really tick as bad at idle as it does at higher rpm. Around 2k rpms you can hear a fast rapid clicking noise. It really sounds like its only 1 but not even sure if that is what im hearing. Tomorrow I dont have work so im planning to pop the valve cover off and take a look. Can anyone help me out in what to look for etc. What else may be causing the ticking problem? Thanks alot, really appreciate it guys.

theres a way to fill the lifters back up if they ran dry somehow. its in the mitsu manual. basically sit the car at idle and hold the rpm to 3000rpm for 15 seconds and let off, then repeat 10-15 times and if it goes away its the lifter, if not then something else is loose in there. how bad does it sound? its not super loud is it?
|
Mmm, alright I can try that.. and no its not super loud at all but is noticeable.

If you have a downpipe, you might want to check it for clearance issues. I had a bad ticking metal on metal noise a while back and found out it was my downpipe hitting the case. I banged up the dp and no hittin now :)
|
take a peep under the valve cover to see if there is anything thereout of place
|
Here is a video, taking the cover off soon, just wanted to get some more opinions.

http://www.youtube.com/watch?v=ldx5DfanUlg drain the oil first, but as you're draining it look for gold shavings/ flakes if you see them you spun a rod bearing. i hope you didn't, but it sounds like you did. pull the pan, make sure you take it off carefully with a pry bar, don't bend the edges if you can avoid it. then if its not rod knock put it back on using RTV gray silicone. |
make another video and put the camera to the valve cover and then down to the pan.. if it gets louder at the pan in the video its rod knock.

I dont plan on starting the car again if thats the news, ill drain the oil and see if there are shavings in it :( ugh

sounded like a collapsed lifter even tho i couldnt really hear it well
|
Well I guess what im going to do bleed the lifters to see if it still happens. If not then the next step.

I had the same valvetrain noise in my Evo about 4 months ago...I ended up using Justice Brothers engine treatment and the noise went away.

sounds too high pitched & fast to be in the bottom end, most likely just a bad lifter.
when you pull the VC to check the lifters check for any binding, wear or looseness of the roller bearing on the rockers, had a customer car once that had a bad (stuck) roller on one rocker & it sounded identical to a bad lifter |
