    this lovely sound

    last drove the car 3 months ago, sounded fine.

    went to drive it today. got this loud ticking sound. checked oil, sucker was low. i put oil back in, subsided. at idle its not there (sometimes.)

    i did notice one of the ac bearing bolts was loose and i tightened that, had no affect on the sound what so ever. comes only from the drivers side.

    i suspect rocker arm's but cant be sure.

    wasnt sure if someone else had the same issues before?

    Can't hurt to check the valve clearances. How much oil did you have to add?

    Pull the valve covers and turn it by hand, see if any valves are stuck.

    2 quarts is a lot but since it holds 6 that should not have caused any problems. Why was it so low? Either you never check it or you have some large leaks. Don't over-fill. Check when cold, like first thing in the morning before you start it up. Make sure it is level. I like to keep mine in the middle between low and full. Check valve clearances. Fix any leaks.

    Agree with this physical inspection. I believe Rich_NYS had a similar problem, that I think was caused by a blocked oil hole in the rocker area?

    Not saying your problem is the same, but the noise warrants close up inspection.

    thanks for your reply's, guys!

    so I took the car out last night for about 20 minutes. oil pressure is good, drives fine. the sound gets louder when giving it gas and esp at higher RPM's

    im going to flush the system this weekend and put in all fresh oil with new filter.

    I checked the oil this morning without running it and its at full.

    I wouldn’t keep driving it in hopes that the noise will just go away. Depending on what it is, simply parking it and investigating the noise will save you hundreds or even thousands of dollars in repairs, instead of revving it up which might tear it up more.
