Or how about the guys with the 2LTEs I know they have the same shim sizes. I'm wanting to do this quite soon here as the ticking is getting pretty good when cold and my mileage I've noticed is down just a bit. And just to let you guys know this slight ticking on warmup has been very very very slowly getting louder since mid winter so it is nothing new. Its exactly as what a valve that needs shimming would need and my motor does not go through any fluids at all or smoke or miss. Except one miss on startup on first crank which may be from the valve being out a good bit. If any of you guys know I'd really appreciate even a guess or a point in the right direction.
