Replying to: p53mustang (Feb 24, 2005 6:40 pm) Thanks for the advice with the locksmith alteration(which I may be reproducing as well). The dealer informed me that the transponder and master key codes could be reprogrammed, thus eliminating the use of the stolen valet key. So in theory even though the valet key will still engage the driver door and trunk cylinder, the doors will still remain locked due to mismatched code signal. So I had this done at a cost of $230.00 including new valet key. I'm still a little dubious about it to say the least..and may have the keys physically altered ultimately. Cheers and thanks again |

Replying to: markjenn (Feb 28, 2005 8:41 am) The noise does last for a couple of minutes. Pitch is hard to describe, but it's lower than a "tick" but not a "boom." Definitely metallic. Think of the sound an older diesel engine makes...."clattering"....only this sounds like only one cylinder, rather than multiple....Does this description make sense? Does anyone know if these engines have aluminum pistons? If they do, and that is the cause of this noise, I would expect it to sound more like my 6.0L GM that clatters with all 8 pistons slapping when cold. This sounds just like that, but with a singular sound source, not multiple. BTW, I agree with you on wanting a car fresh off the truck. All owners manuals say to avoid "full throttle acceleration" for the first 1,000 miles, but who test drives a vehicle without doing exactly that? I don't even want to buy a vehicle that I test drive! LOL Thanks, Tom |

I hear the same noise on my 2003 V8. Sounds like piston slap to me.

I have a 99 4runner limited. It has the electonic air controls and auto climate control. The past two months it has acted Sporadic. I dont ever use the auto climate. I cant even change it from fresh to circulate sometimes. The buttons will just not respond and I am not able to turn the ac on sometimes or even put on the front defroster. I know that you cant do some functions while other are on but this unit is just acting wierd. Sometimes I will get stuck in circulate mode when it is raining and my windows will fog up, I just cant go into fresh mode. Any ideas or do you think I might need a whole new unit? I imagine that a new air control unit is atleast $200-400 bucks. Do you think the clamp in the back is loose or the wires are to crimped or something? Thanks for the ideas!

Replying to: nedzel (Feb 28, 2005 11:48 am) I just need to know if this is a common problem with this V8, or very unusual. If it's common, I am not too concerned about it....don't like it, but lived with a GM with the same problem with no apparent long term damage. I would still appreciate hearing from others with the 4.7L V8 to see how common this is. Thanks, Tom

Replying to: polartoy (Feb 28, 2005 7:53 pm) I read this entire topic before posting my question and there was not one reference to this noise with regard to the V8. Therefore, I thought I might have an unusual situation that was cause for concern. My experience with piston slap is that it is not as bad as it sounds. And, I agree with you that synthetic or dino makes no difference....seems to be totally temperature related. I'll relax about what I'm dealing with, but it bothers me that my service department acted like they have never heard of the noise. Tom |

| Don't get me wrong.. I absolutely LOVE my 4Runner. I've had it a year now, and it's an awesome piece of work.. haven't had a single problem with it, not one! But while up in Colorado recently, I had problems several times with it automatically doing the slippage thing on me. What I mean is, if I'm in a small bank of snow or mud, or on any ground that is slippery, instead of being able to power up and kinda spin the tires and work the vehicle up and out of the area.. it does that clicking sound, as (I'm guessing) the differential gives way until you regain traction. I believe they put that in place to detect and account for things like hydroplaning. But when you're in a vehicle like this (and you're using it to it's capabilities), you're going to find yourself in less than desirable off-road conditions from time to time. I live in Dallas, so I didn't really feel like I needed a 4WD.. and a 2WD would be fine if it just didn't give way when I'm trying to power up when the wheels can't catch traction. So my question is.. is there a way I can disable this function? If so, would I just lose out on that auto-detection of slippage, or would I be sacrificing some other major functionality? I found it pretty embarrassing when I was stuck in a small amount of snow, and I can't generate the HP to rock it back and forth and up and out of a hole or small snowbank. And the sound it makes inside the car always gets a "Whoa, what is that? That sounds terrible." comment out of any passenger. Thanks for any help on this! | |

I've had my LTD/V-8/4WD for about 2 1/2 years (it's out of overall warranty; has 45K miles on it), and a month or so ago noticed an undercarriage rattle. Today the dealer told me it was a leaking front shock, and that the X-REAS system won't let you replace just one shock...YOU HAVE TO REPLACE THE WHOLE SYSTEM! It was going to cost over $2,000! Fortunately, the distributor is going to cover it for me...but, damn! Word...if you get the X-REAS suspension, get the extended warranty. Your dealer and/or distributor may not be so customer focused. |

I just recently had my header gasket replaced, thinking that would stop the ticking. Found out that it did not. I understand that there maybe a slight ticking from the injector's, but I am just scared that it could be a busted head gasket or a push-rod. If it is a push-rod can you adjust the rocker arms. To stop the problem. Any help would be welcomed...
