Robert Schmidt: Wondering if all this work was in vain. Like he said everything looked good and clean. This is why you need to check the sparkplugs first because 99% of the time this noise is just a simple loose spark plug and normally it is the exact one where he is having the noise on the drivers side front.
james dean: Before anyone freaks with anything regarding lifter tick CHECK TO SEE IF YOUR EXHAUST MANIFOLD BOLTS ARE BROKEN!!!!!!!!!!!!!!! and make sure the exhaust manifold is flat to the head and there are 6 bolt heads on each side. I don't believe all the lifter tick stuff for the most part though iam sure it can happen. Mine had the same thing going on especially on start up and my bolts were broke. Everybody was telling me lifter tick it's lifter tick !! but it never sounded like metal on metal contact to me but more like air being pushed out. Sound goes away as the aluminium heads expand from heat thus closing the gap with the exhaust manifold. if you get lucky like i did, you can back out the remaining bolt with vise grips. If the bolt broke flush with the head you'll have to use an extractor for broken bolts but their is a product that makes it easier by just clamping the manifold down in a completely different location using unused pre threaded hole's higher up on the hea
Thomas Russell: Diesel gas? Lmao
Scoobydoo 39: had a knocking from passanger side valve cover was pretty bad came out of no where. from cold start was loud within 5 mins slowly and slowly kinda went away. then threw out the day no issue only when sat over night. was doing this for few days. i put seafoam in crankcase drove around a hundred miles or so. changed oil an for now it starts like new truck. hopefully will be good. 2004 gmc sierra 238,488. so far an i kno she is going to go over 300,000. everyone knocks seafoam. but seems to have worked on my issue. well for now
jorge ulloa: instead of taking the rocker arm part can i pour the b12 true the little hole at top
gary mathews: on gm based ls motors ,also check any pushrod for straightness ,by rolling them on a flat surface .check the rocker arm trunion bearing for any looseness ,they wear out ,or the needle bearings come out . check out Texas Speed for parts for ls motors ,great price ,fast shipping .ls1 tech is a good source for ls engine information .
Arland Barnes: hey I seen this video I really like it I did it and a little bit later within a couple of weeks it's slowly came back do you got any suggestions besides trying it again
Jzjesse1: How do you put the rocker arms back on?? Tighten by hand or torque wrench?
Jason Wells: And now ls maintenance, with John Malcovich! lmao... just kidding. Nice video! I learned things.
StingRayNet: My 2006 Trailblazer had a slight "ticking" noise on start-up that quickly dissipated after a few seconds. It was my thinking that one of the lifters was clogged. I introduced 6 oz of the Seafoam as per directions directly to crankcase thru the oil filler tube. I immediately started the engine and ran for a few minutes. The "ticking noise" has completely disappeared. My plans are to put less than 500 miles on the Trailblazer before changing the oil. Hopefully this is all that was needed.
Brian Kent: So what actually CAUSES the ticking noise? Is it a flat spot on the roller? Or is the rocker sticking and popping back down? Just wondering how to think about fixing my 05 Suburban with the same noise, vs. hiding the problem. I noticed the ticking went away for a bit with my last oil change, but it comes back after a short while.
jose oriol sanchez sanchez: hola, mi chevy silverado 2003 posee ruido semejante, al parecer el ruido proviene del area de engranajes, tensor o cadena de tiempo, podria enviar un video guia para saber
Sbmf66: 2006 Envoy, same exact cylinder as your video. I did exactly as you suggested, except I didn't have to pull the rockers. I could easily see that the lifter was low and allowing the pushrod to be loose. I was able to put the straw straight through the rocker into the pushrod. Replaced the valve cover, flushed the engine with motor medic by Gunk. Fifteen seconds into starting the engine it quit tapping. oil change and it's all good. Thanks for the video, I'm actually kinda stunned that it was this easy.
Paul Sosa: I'm getting this ticking/taping noise but only under load/acceleration. I've done oil change and additives but still there any ideas what's going on?
Sean Hunter: I have 03 avalanche with same issue...you recommend using seafoam or the motor flush for this issue ? thanks
Shawn Szentmiklosy: Question: my 2005 chevy suburban 5.3 makes same exact noise. Fist start sometimes quiet then gets louder. Then oil pressure drops sometimes. After it warms up sound disappears oil pressure stays up. stopping to get gas or what not you hear it again then disappears. So what is it same thing? Oil sensor where is that located?
patchreefs: Brian didn't realize it was you talking forget the oil change idea.
patchreefs: Could be caused by dirty oil. Do you change every 3000 miles
Orlando Alcantara: its the same problem i have on my 02 chevy avalanche ..5.3.....
