    OK here is what happened...I was in the Jack in the Box drive thru and was moving up to the window...well I put it in 2nd and forgot about it and ended up getting on the highway and driving 70-ish for 10 miles or so. When I came to the light It was pinging damn bad. I got to work ( yeah Sunday night at 10:20pm ) and parked leaving it at idle and reving it there was some bad pinging going on. So I turned it off and left it for about 5 minutes. When I came back out and turned it on I left it at idle for approx. 2 minutes and it slowly went away. Now when I rev it up it doesn't ping. I haven't drivin it yet but what coud I have done to her? Later

    You probably over pumped the lifters. There are special lifters for high reving. They are anti pump up lifters so that doesnt happen. If dont have them they fill up with too much oil and make the valves go out of adjustment. Thats why it was making noise. I am assuming it was a chattering noise. I would change the oil. Being at that many rpms for 10 minutes brakse down the oil pretty bad. When I race the firebird I change the oil every other week. It breaks down real easy at igh rpms. I would also adjust the valves.

    A friend of mine did that to a somewhat tired 350...and spun a bearing.
    Hopefully that didn't happen to your motor!

    One thing also to note is that I have had lifter problems in the past because I was misinformed and using a 20W 50 oil type. I had my local shop do a "Cleansing of the system" and it fixed the problem alltogether. I really hope I didn't spin a bearing. I have financial woes coming out of my ass right now. Hell it might be time to learn how to rebuild an engine! hehe...I bet my boy ARQ doesn't want to hear this right now! hehe...

    Sounds like you over pumped the lifters. I have done that one in the firebird even woth anti pump up lifters. I let the line and spun the tires so bad that it went straight to redline, tried to shift to the next gear to help out and kept spinning the tires through 2nd and 3rd. When I circled around to the pits I heard the same thing. I drove it home and it went away.
