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.

that sounds like rod knock. stop running the car and remove the oil pan and check for rod bearing play before you cause anymore harm to your motor. If it is rod knock and you continue to run the car the bearing shavings will destroy everything oil touches including the turbo, cams, oil pump, oil cooler, and the list just goes on and on.

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

Well, it sounds like a lifter to me.

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.

Good Luck, hope it's not something bad.

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

I know the sound quality on the video is bad but thats what it sounds like fast rapid clicking coming from the valves. I had the car running today for couple minutes and tried to listen in the bottom end and I really dont think its a bearing. Im going to take out the lifters tomorrow or saturday and bleed them and hope it goes away. If not ill drain my oil and look for shavings. However it is october and starting to get cold in Connecticut. I know these motors are notorious for noise and never really experienced it in the cold with 272s, and supertech valve springs and retainers. So im hoping thats why they are ticking. Wish me luck lol.

almost 100 percent its a lifter. i had same exact noise. and to fix it i put in jam non-ticking lifters :) lol sound like a bunch of bs but deff worth every penny

Thanks for the less stressful opinion lol. Are these them right here?

I have a similar prob right now. Put in a 2.3 stroker and the noise started like a month after....so obviously I pulled the pan and the rod bearings were beautiful...looked just the way they did when installed. The noise is definitely coming from the head but upon inspection, nothing is visibly wrong including rollers..I'm at a loss. Replaced the lifters with 1g lifters on the number 1 cylinder which is where I pinpointed the noise and no help. the noise is coming from the front timing belt side of the head...:confused: Whatever just drive it til it breaks. thats my theory ever since I figured out it wasn't the bottom end.

yup those are it..id say give it a shot. it worked for me, just follow the instructions and you should be tick free.

make another video reving it higher quicker and letting off.. ill tell you if its a lash adjuster or a rod knock. if you didnt let the motor run low on oil its not likely rod knock.

Here is the scoop, finally got working on the car today with a buddy, it is definitely not a spun bearing. We took everything off, took out the lifters and bleed all 16. When we started up the car seemed like every single one was ticking so it sounded like a gatling gun. After letting it idle and what not seemed like most of them filled back up. There is still ticking, so I assume it is 1 or maybe 2 lifters that have seized and/or busted. Im guessing ill order the new lifters and try those out. Thanks for all the inquires and comments. Ill keep everyone updated.

i bet you're happy it wasnt the rod bearing.

as for the ticking like crazy its normal. start the car up let it get to running temp and then rev it and hold the rpm to 3500 rpm for 15 seconds then let off.. and repeat this about 10-15 times until the ticks are all gone :thumbup: this is documented in the service bulletins and this is how you fill the lash adjusters back up.


ADD:

btw if you bled them all and didnt notice anything weird with any, then chances are they are all fine. just do what i mentioned above and you should be tick free.

Identical problem, I've replaced lifters, swapped out injectors, undid the vacuum line to the pcv and that wasn't it. Haven't pulled pan yet but its quiet under the car really sounds like its on top. Hopefully I can figure something out, let me know how things go for you.

Thats exactly what mine sounded like, my phone took a crappy video audio wise so it sounded a lot worse.

Crckhead and tjsapoo....did you ever figure out the noise? Mine has the exact same noise which started after a 2nd gear pull....What was wrong with yours?? Yes I know it's an old thread sorry but better than making a new one

well if its still making ticking noises and goes up with rpms somewhat, yet its not a lifter or spun bearings, id be more inclined to look at your serp belt tensioner, or possibly one of the pullies as a suggestion. Sometimes a pulley going bad can make some ticking style noises, which under right load can make it sound similar to a lifter tick.
