  1. 2015 chevy silverado 1500 LT 5.3, 6 speed. Leveled 2.5 on 305s 97k miles Recently started to get a lifter tick noise, took it upon myself to pop the valve covers off and see if any rocker arms have any play(none have any play). Fried it up with valve covers off all valvetrain works and looks really good. Truck runs great, no check engine light, no misfires, idles amazing. My only idea now is to pull the rocker arms from the passenger side and inspect the push rods. That's the side I'm hearing the tick. Gonna buy a couple just to have in case I'm right. Any insight or should I just keep driving till I get a check engine light? Lol
  2. Has anyone installed a water/methanol inject kit on any of the small blocks (2014-2018)? I personally have the LV3 4.3L V6. Looking to eliminate the carbon build up, caused by direct injection, on the intake valves. Right now I'm trusting that Sea Foam is doing the job every 30k miles. EDIT* I'm also interested in the increased performance after tuning. I am aware that a catch can would eliminate the majority of carbon build up on the valves.
  3. OK, so I've tried searching here and the interwebs for this, but only get stuff related to the transmission clunks. A little back story.... I live on top of a hill, so every morning, to go ANYWHERE, I have to go down said hill. Rather than use up my brakes, I let the engine "help" me slow down by manually down shifting. What I'm noticing lately is, if I down shift to 3rd gear, and the RPMs jump up to say, 3K, I hear a quick "thrash" from the engine, almost like its trying to adjust the variable valve timing or something..... Then, POOF, its gone, and all is well. It will repeat, however. My question is, is this a sign of a bad lifter, or something else? It's not just ONE lifter tick, and I would think it would do it all the time if it was a bad lifter..... I plan on bringing it into the dealer shortly, but I'm figuring they will say what they normally say, "Normal operating noises"..... Truck has 84K on it, and has had Mobil 1 oil changes every time the oil life interval said to change it, short of the very first one I did early.... And the oil life has no bearing on the noise....
