Valve tick?
 

Can someone please direct me to a thread where I can find something that is related to my issue?
The issue is when I'm driving on the freeway and no music and windows are closed, I could hear the valves ticking kind of like on the passenger side and they get loud when the rpm rises. I'm assuming it's the valve and it sounds like it is low on oil but just had a oil change in the same month. Mileage right now is 20K and it wasnt tickihg like that before. Should I use a heavier oil?

Did you change the oil yourself? If not, make sure the shop put in enough oil. Could also be an exhaust leak.

Done by the dealer. I even checked and the oil is new

If the oil is low, the oil indicator on the cluster should come up right?

Take it in and have it checked!
There are many threads on the subject here but not every sound means the same thing.
This may help you a bit.

Never ever rely on the light!

That oil light should be called the "you've just blown your engine" light. By the time it comes on the damage is done.

Attachment 102024this is the dipstick right now. I guess the oil is too thin, you can barely see where the level is at.

Wipe and dip again. But, if its making new noises I would take it in.

I did. That is actually the 3rd time to make sure what I was looking at. Yea I may have to do that tomorrow.. The tick noise is kind of similar to the miata HLA noise. I used to drive one that's why I'm familiar with the noise.

It's not injector noise is it?
These things make sounds that would have had me cringing in terror with my old V8s!

No not the injector. The tick noise is rapid. I'll try to take a video in a bit.

Listen to my ticking noise...and compare it to mine.

I have that tick too.. Lol.. So actually there are 3 kind of noises I'm hearing and that's one of them. The others are the chirp and the other is somewhere around the passenger but inside under the hood.. Can hear more when you're actually driving and inside the car is quiet.

Yours sounds like a single noisy lifter. I'll say that's my "final answer."

Mine sounds a need to tear the engine down (not joking).

Oh, I'm with you. Following your thread. Thanks for sharing that.

Just trying to bring awareness!

Knowledge is power. We are all the beta testers. That's the way it's been since the first one rolled off of Henry Ford's line. At least we have the interweb.

(well before Ford but you get my drift...)

You hunch was right about a noisy lifter. It was a rocker arm. Scarred the engine.

Damn. Here's what I was thinking when I heard your clip. Apparently it's a quality control thing. Not sure if exactly the same but they did tell you it was the rocker. Hmmm...

OP - use a piece of scotch brite on your dipstick. It will make it a lot easier to read. I can't say why, but it worked great for me.

This picture scares me.

can you get a picture of the bad rocker?

Those were modified deliberately.

:lol:

I'll try to get pictures of it.

Guess I could have been clearer!
The top is stock the bottom was modified to correct the off center issue.

The pair were purchased, one for engine repair, one for testing.
@Element Tuning is showing us the inconsistency in the swaging process. The top one takes less force to back out over the corner where the die struck offcenter.

edit: Upon closer examination of the photo after discovering it was a high-resolution image, (duh), the assembly/joining process appears more complicated than I first concluded. I'm not sure what was smushed into what but the top one doesn't look smushed properly.

I totally misread it then!
The top one is a mess though.
Be interested in seeing N1rve's fail one.

Right?

:popcorn:

An easy way to locate a ticking sound like a rocker is to get a stethoscope from an auto store. unlike the Dr. type it will have a rod on the end (about 12in.) that you can place against different parts of the engine. A single loud rocker is easy to find. The same for an injector.

Especially if he's Ted Nugent.

I've been inspecting and listening very careful, even driving around with no music and looks like we have the same issue. "Tapping" is the best way to describe it and like what you said it gets loud when you drive it and somewhere around the passenger side. The thing is idk what my warranty type is.. From what I know, my free maintenance is 20K only and they said something about warranty up to 35K.. My current miles is 21K and I just had my last service and according to them, the noise is "normal"

Scion provides this...

Maintenance (Oil Change/Tire Rotation) - 24 months or 25k miles, whichever comes first.

Bumper to Bumper (Everything except wear and tear) - 36 months or 36,000 miles, whichever comes from.

Power Train (Engine & Transmission Only) - 60 months or 60,000 miles, whichever comes first.

What dealer did you take it too?

Puente Hills Toyota/Scion. Did you get yours fixed?

Currently in the progress. Toyota Engineer will be here tomorrow to inspect the engine and begin reinstalling the engine along with performing tests on it.

Take it to Longo Toyota. Let them know of your concerns and replicate it to them. Record it if you can.

Ok.. Cool! Thank you!
