Re: Ticking only at idle Sign In

You probably have a weak lifter that doesn't pump up at idle. There are a couple things you can try.

Get a quart of ATF and add it to the engine oil. Run the engine for about 10 minutes and drain the oil and refill with 5W30.

If that doesn't help. you may have to change the lifter.

Now if this noise gets louder when the A/C is turned on, then it could be something entirely different. They have a lot of problems with Harmonic Balancers separating and making a noise like that.

No, it won't hurt for that little time. If you want to play it safe, just use half a quart and don't work the engine too hard. The detergent in the fluid will get to places regular oil can't.

You can bring the RPMs up to get better circulation. Just don't get over aggressive with it.

Don't worry about adjusting them. That's not the issue here. As I said in the first post, you still need to confirm that it is actually a lifter making the noise

I don't know. I'm not there to hear it. There's only so much I can tell you from here.
