hmm i have the same sound, only i thought it could be a lifter. only way to find out if its the injector is to swap it with another and see if the noise moves.

 

Yea, I might do that, but it's strange because all 8 do that, surely all 8 didn't just go out.....?

 

Probably one of the reasons they had insulation under the hood.

 

Injectors do that. I have one that clicks from time to time. Try dumping a bottle of Marvel Mystery in your gas tank. It should lubricate the injector as it passes. Nothing to worry about.

 

yeah thats pretty normal its the injector pulsing

 

Oh ok, didn't know if it was something that I should worry about fixing or not, this Marvel Mystery, does it work good?

 

Yes, and it goes great with coffee.

I use 1 ounce of 2 cycle oil meeting TC-W3 standards to 5 gallons of gas. Runs smoother, keeps fuel system clean, and maybe just a smidgen better mileage. I even use it in my John Deere mower, it helped the fuel consumption noticeably in it.

 

Hmm,, You guys ever hear of adding a quart of ATF to the fuel tank?
some guy told me it was a mechanic secret , and was same as marvel mystery oil , just not in a pretty can .

This true?
