Do you hear a lot of rocker chatter?

Does everyone else hear a lot of chatter coming from their engine? It makes way way more noise than my 66 stang!

I just purchased a 2001 Bullitt and at a stop the idle seems a little rough, but not surging or anything... the engine only seems smooth and happy when i really push it. I'll do it's 60k tune up soon and see if it smooths out. But the main concern is when I get it over 3k rpms the chatter from the engine is pretty loud... I end up turning up the radio so i don't have to hear it and worry.

I think i need to find one for sale locally i can drive and listen to... then compare it to my car.

Comments or thoughts???

What should I do for the 60k tune up besides what is mentioned in the manual. I plan on tracking this car 1 or 2 weekends a month (open road courses) Laguna Seca, Buttonwillow. So far I have MM cc plates, mm Panhard bar, CHE LCA... i'm slowly collect parts and will install everything all at once. I want to run totally stock for a bit, learn the car then see what a difference upgrading everything at once will have.

my car seems pretty smooth 99 gt with 165,000 miles. I bought it off the original owner and it was maintained VERY well. the only problem with it is at idle it sqeaks a lil, but nothing new belts cant fix.

I'd look more into it man

You shouldn't hear any rocker arm chatter.... These cars don't have them.

Now that my unhelpful and otherwise smart ass comment is out of the way, the noise you are hearing is likely from the lash adjusters. Not always, but running oil heavier than 5/30 can cause them to be a little bit noisy, but based on the severity you described they may need to be replaced. Could also be valvetrain noise.

I said rockers not rocker arms... And the SOHC DOES have rockers. I was using that to give you a clue of the sound i'm hearing. If you're familiar with a pushrod engine you know what rocker chatter sounds like.

I'm using the required weight oil. I really need to find another one and compare. How often do lash adjusters go bad? how do I check? If i end up having to take everything apart and get into the heads i'll probably just get some modular head shop stage 2 heads and install them while i'm at it.
