spark plugs/ ticking noise
I have a 2002 tacoma ext cab with the v6. I think there is a slight miss in the motor. I checked the plugs just to look at them and noticed that i have denso on the driver side and ngk on the passenger side. Is this normal for toyota to do this or what? Any knowledge of this would be helpfull. 2nd question when i start the truck after it has been cold, i here a ticking noise for about 4 seconds. Seems to me that once the oil gets circulated it stops. Icalled dealer they told me wasnt anything to worry about probaley a lifter bleeding down. I thought that over head cam motors had no lifters. Not sure if dealer was blowing me off. Any comments will be appreciated thanks scott.

as far as i know... ngk and denso are the exact same plug.
at least... thats true as far as honda's go. i'm pretty sure that applies to all ngk and denso...
(i'm a honda guy too, please dont hurt me! **ducks**)

ngk and Denso
Yes, I noticed the same, I was pissed...I thought previous owner had decided not to replace the difficult to reach ones. Now i see it probly came that way from the factory? I don't understand, this logic?

Ticking noise...
Well, I can tell you that in my previous world of mitsubishi's, we called that "lifter tick" and was really a product of the hydrolic valves not getting enough oil on startup, and was usually much more pronounced in cars that ran either a light weight oil, or synthetic oil. The problem was simply that the oil pumps did not flow a high enough rate to keep oil up on the head quick enough. Our simple cure was to run 20/50, which is a bit thicker and allows the oil to stay up on the head/valvetrain. I have no idea if toyota is the same way or not, but that should solve it if it is.

Well, that dealer sure sounds impressive. He clearly does not know that the 3.4 as well as most all Toyota engines use solid lifters so there is no way they can "leak down".
Would you trust these guys to open up your engine and change the head gaskets??

My brother had the same problem when he used Mobil and it went away when he started using AMSOIL.
Of course if you need a valve adjustment, changing oil brands is not going to change that, you will still need a valve adjustment. Mine where all in spec, but it sounded terrible for some reason with Mobil 1 in it. I am sure others have had just the oposite result, but it is worth a shot, right?
