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

Plausible it's a push rod noise but the more common thing is just the lifter being noisy. I haven't owned a GM LS/LT engine that doesn't have some sort of minor lifter tick noise. And pair that with the really loud direct injectors, these engine always make noise.

Check your vacuum pump the 15's and 16's had faulty vacuum pumps which sounds just like a lifter or rod tick. May not be the case but you tube it. These motors aren't quiet on good day though lol.

Thanks guys, yea I replaced my vaccum pump with the new updated one, I was wanting to delete it but I'm to lazy to go that hardcore on this truck, I added a extra quart of oil yesterday just to try, and oddly is running alot more quiet. This is my first winter in reno so maybe just needed extra? Lol I'm just gonna keep running it.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thanks @newdude, guess I'll keep looking.  Test driving so many trucks that have obvious things broken, I'm thinking "if they couldn't even be bothered to fix the power seat," what else is broken".   Just drove a 2021 where the power seat motor was grinding/binding and wouldn't do anything but make a terrible sound.   An owner that puts dents on the bumper, doesn't fix a seat motor, and had spotty service intervals (along with missing major services) doesn't give me the best of confidence.   Amazed at the number of people that will finance a $60k+ truck, run it into the ground, then trade with a loan balance (every single one had "loan/lien reported" on the CARFAX at the last year of registration).

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.
