    Re: The engine has developed a knock

    Sorry haven't got back to this. been pretty busy. To answer a few comments. The MAF delete is because of the SD tune. The CEL was not on when I bought the car. I had the clutch replaced and when they hooked the battery back up, it was there. It was scanned and found out to be the MAF. I picked up the car and was told it need to be re-flashed with the tune to have it Permanently turned off. I do not have the knowledge to do that nor the balls to reflash it without thinking I would mess it up. The more I here it and think about it, I think the header gaskets may be leaking. Hope this helps. I will butt out of this conversation so others don't think I am trying to make excuses.

    OP, give me a call if you need anything from me.

    Are you saying the tune was deleted? The engine has been running without a tune!

    No, I am saying the MAF needed to be turned off. The easiest way to do that was with the tune. You would definitely know if it didn't have the tune.

    ApacheDriver,
    Did you get the car tuned when you had it or were you running the tune from the previous owner? just curious.

    Re: The engine has developed a knock

    what city was the car tuned in, and what city is the car in now? (I'm curious about the altitude difference)

    ...just, assuming the car is in the same running condition as when you picked it up, and no one's integrity is in question (nor is the integrity of the car).

    easily ruled out if there was a gain in altitude, or no change. (no harm in asking, right? at the worst I'm wrong, and I'm ok with that).


    robojesus: the subs comment, also the first time I knew of you. ...so I assumed robojesus was a troll account, and that you were game.

    Tuned by previous owner. I did not change it. The tune is on the flash drive with the EFI live

    oh, no... this isn't a troll account. I just think you're an idiot.

    welp, looks like it's not the altitude thing, and I don't have to quit the internet

    this thread is a LOT of fun. I think we should all take a dance break.

    yesthankyou robojesus, I am now aware that you are dead serial, and I will not disturb you henceforthwith. promise, girl scout's honor. (but in my defense, I don't think I'm a lot dumber than you thought that I think that I thought I was once.)

    amen.

    Efilive is on the CPU, just need to find time to play, put it in the air and have a good look around as well.

    Re: The engine has developed a knock

    I got it to the shop Saturday, he pulled the valve cover today. Says it's a collapsed lifter and has to pull the head. Is it necessary to pull the head to replace the lifter?

    Yes its the design of the LS motor. Glad he found something. Hopefully it didn't beat anything up!
