Lifter tick or something more now?

I noticed around a month ago that the "tick" noise got more prominent. Right around when it got colder outside. My oil pressure has been fine and i haven't had any lights come on. But the 20w50 and lucas trick isn't keeping her quite anymore. Are my lifters just that bad now or do i have a bigger issue? I have two videos (sorry for the quality) one is just with her idling and the other is with some gas.

Sounds more like rod knock to me.

Well is it going away after some time?

I started my car today and the lifter tick was bad. I just turned the car off and then back on again and the noise was gone. I really do think lifter tick gets louder as it gets colder outside. BTW, I never rev my engine just in case its something else. Just let it warm up and does it go away?

Rod Knock doesnt go away. Lifter tick does.

It seems to come and go and gets quieter while driving. If i am sitting at a light i can hear it, go to the next light and it will be gone. So i still feel its lifters but not a 100% sure anymore. Might see if Tim has some free time and have him take a look at it.

Stop running it and open it up... That's a bag of hammers. Have you done a compression test or leakdown? I would guess a min of one cyl is under 100. :Doh:

how many miles on it?

I am at 132k But the noise seems to come and go. This morning i started it and nothing. Then it slowly came back but faint and then went away.

also sounds like rod knock to me. pull the pan and check it before you need a new crank.. 20-50 ??

Hard to tell with that crappy sound clip. Could be rod knock, could be a loud lifter. Get a better clip.

Not sure what everyone is saying. Correct me if I am wrong but a rod knock doesn't come and go.

Just curious. How does a rod knock come and go? Doesn't make sense.

if you do not want to drop the pan get a steth from autozone and listen to it. its only a couple bucks. if you dont feel its necessary keep driving it and you will find the cause. we had one the previous owner also said it only made a noise once in a while. tore the engine down and bearings were not spun but wore bad enough the crank was bent .030 and a new crank is about $800. hopefully if you have rod knock the bearing is only worn and not yet spun. take time to check it out

The oil takes up the slack in the bearing.

So i just got my car back from having the lifters and VSS replaced. The original noise is definitely gone, but its been replaced by a new noise. The noise only happens when it falls under 1k rpms (only while stopping, doesn't do it at idle.) But its like a little metallic drum roll. I was told this will go away once they have had time to adjust. But i just want to make sure this inst something i should worry about, or is out of the ordinary.

New lifters usually don't make any noise after 30 minutes of run time. Even with new lifters, you could still get lifter tick if you have bad oil pressure. I would drain your oil and see if there are any metallic flakes in it. Those videos sounded horrible.

After the lifters where put in, it was drove around for a we bit. The the oil was changed and he said it looked fine. But i dont think i am at 30 minutes of drive time yet. I have a few places to go tonight so i will get the time in and see if it goes away.

Keep us posted.

Well i ran all my errands and i stopped hearing the noise. But tomorrow is another day, so i will post more tomorrow.

Started it this morning, it gave a noise for about 3 seconds (faint) and haven't heard it since. I think i am in the clear. Thanks everyone for your support.

Good to hear.
