They Only Lasted 1,050 Miles... What A JOKE ! Thanks PRW For Trash Parts
Rocker Arm Kit That Saved Her - www.michiganmotorsports.com/l... - Auta a dopravní prostředky
Soundin real good now👍🏼
Thanks for posting this, gonna get this kit for my 2002 Trans Am!
Good thing man !
Damn it, just installed the kit for my rebuilt ls3 headed 6.0, an hour ago. Glad it’s still on the stand. Thanks 👍
Just in time !
@@KidKevi absolutely. Thanks again. Ordered a BTR v2 needle bearing kit. After measuring the prw modified trunnions & bushings, gonna pick up a set of BTR replacement needle bearings (sn105) & clips. Then run them in 5.3 I have.
Yep , you'll get one two or three bad lifters out of 16... And you'll get one two or three bad roller rockers out of 16... Expect to go back down elbow deep twice... If you're lucky, it's a cross about every brand...
Thank you
Nice job
Thats a knock!
I’m lucky it wasn’t
How did you open the valves for lift when you tighten them. Did you spin the back tires in gear.
No, I used a socket and break over bar, spun the motor over by hand via the harmonic balancer bolt
I have a tick on my driver side that sounds very much like this. I have an all new valvetrain, minus the rocker arms. I’ve even tried three different sets of lifters so I’m starting to think it’s a rocker arm issue. I have factory LS3 rocker arms with CHE trunnions. Pretty much all of them have lateral movement when the valve is closed, which I though was normal, but my isolated tick is on cylinder 1. I think I’m gonna do BTR rockers with their V2 trunnion upgrade
Definitely go with an encapsulated needle bearing kit , the bronze bushings are garbage man !
@@KidKevi yep apparently so. I have gold glitter in my oil so obviously the brass trunnions are already wearing down. I’m pretty sure the BTR v2 kit is a needle bearing kit. Idk if my lateral movement is normal or not and it’s on several rockers but the ticking noise I have is only on cylinder 1. Makes no sense at all!
@@bwill03z76 key word is bushing vs bearing , the rockers eat the soft bushings ha ! Understandably so , I guess it was a good concept but in real world high performance engines it doesn’t take the cake 👎🏼
Get a pushrod length checking tool and measure for correct pushrod length.
@@wally7856 yes , every engine , no matter what
I believe I got this problem still have the stock press in roller bearings checked the rockers they all except two have side to side slope but very little
Seen a similar issue with a vehicle that the cam bolt had backed off a tad and threw the timing off , hopefully it is the rockers but keep that in mind !
Definitely will be taking another look at it and I’ve noticed if I rev it up it’ll tick and when rpm’s come back down or I left my foot off I hear it in the valve train I thought maybe it’s the valve clearance between the valve and rocker
@@josephmontes815 i would definitely check your cam bolt / bolts and TDC before buying rocker arms just in case
What kit you use? My g8 has the same tick. Think it has the smith brothers trunnions
I had ordered and used this kit www.michiganmotorsports.com/ls-rocker-arms-trunion-kits/ls1-rocker-arm-with-upgraded-trunions-installed-and-support-stands-fits-4-8-5-3-5-7-6-0-ls2-ls6-lq4-lq9-ly5-lm7-l33/
I decided to order an entire set due to multiple rockers being toasted
Do you rotate motor to torque rocker arms? Or just torque 22lbs all the way down
I would always follow the proper sequence of torquing them down each at the proper time as you rotate the crankshaft and open/shut the valves. Always listen to GM 👍🏼
Hey just curious is your Camaro with the ls engine automatic or manual cause I’m wanting to put ls in mine
Automatic
I have a 98 Formula that makes a knocking/ticking noise seconds after start up, when the engine is cold. Once it makes noise for a few minutes, it settles down and is quiet again... any ideas if this is lifter or something else?
That sounds to me like piston slap , very common issue for Ls engines , especially the earlier renditions. Typically piston slap is not harmful and means your engine has more hp than a tighter one ;)
My 96 LT1 had the same issue. Motor outlasted the car(Roadmaster Wagon)@@KidKevi
When people tell me the bushings are a good aftermarket option I always say "not when bearings exist"
A lot of people say CHE are worthy but with the way I drive , I believe I’ll stick to what is tried and true. The bronze experiment has came to an end for me 👍🏼
@@KidKevi Amen.
Did it affect the performance of the car or just make the tick noise?
Not really sure but it drove me crazy because I could tell she was hurting !
Can you jiggle the rockers to test for play in any engine position or do the valves need to be in a certain part of their cycle? I know when torqueing the rocker arms, the valve has to be down/seated before you torque the rocker arm, but wasn't sure if giving them a wiggle was the same way.
A rocker will only wiggle at 0 lash , whenever you check pushrod length you go through this process man , always be sure to double check length in any engine build
@@KidKeviI'm a little lost then. I have an LS3 making some valvetrain noise and I've never done this before. This weekend I'll have the valve covers off to replace the gasket and while they are off, I want to inspect the rockers and springs. Basically anything I can see without taking anything apart. Do you have any recommendations or materials I can read to get a better idea of what to look for and how to look for it?
Following just in case he comments with the answers
@@dudeman0248 what answers ?
@@KidKevi what was the problem oh the video was it rod knock or lifters
Do you spin the engine over when torquing the rocker arms?
Yes you have to torque them in a specific manner , always follow the GM engineers procedures
I have that same issue with my ls3 it has drove me nuts with the ticking i also have movement in mine unfortunately way more then you
I will be changing mine very soon
Factory rocker arms ? Or bronze bushing ?
Which bronze bushing kit was that??
I have the CHE kit now I’m concerned….
I went with the encapsulated 8620 steel rocker arm upgrade. Many people have told me that CHE is the best. I wouldn’t worry about it man , the kit in the video is PRW and they are no longer available on summit , not sure about other places though.
You can also check wear at 500 mile intervals to see if the rocker fulcrum has dug down through the bronze like in this video. Good thing I got them pulled out in time !
@@KidKevi yeah I’m glad you caught it. I’ve never heard of PRW, they must have used cheaper quality stuff for that to have happened. I had the CHE kit out in a few thousand miles ago and the car is in the shop right now getting a cam and the builder said he would check the trunnions so hopefully they’re holding up good 👍
@@bwill03z76 good man , yeah I bought that kit a long time ago before CHE was a thing and they sat until I got that engine built and I threw them in , big mistake !
@@KidKevi well at least you caught it before it did any serious damage! LS motors naturally tick but I cannot stand any excessive ticking. I have a video on my page of my bone stock 2011 C6 ticking excessively and was driving me nuts. Lifters and rockers were fine but ended having to have a valve job done. Somehow the seating area was too wide or something
@@bwill03z76 yes I’d say I caught it last minute , for awhile I thought it was a bad exhaust leak and I continued to drive it . Got it in time tho and I ran 2 flushes , ( 1/2 trans fluid, 1/2 Conventional Oil ) at idle for 15 minutes to try and clean out the bronze !
I have an issue on my c6 it’s a LS3 it make it ticking or knock when cold not at idle but when driving in gear you can hear it goes away once oil temp is about 150 would that be the same issue or piston slap?
Sounds more like piston slap to me , this rocker tick didn’t go away with temperature. Can always pull the valve cover and check !
@@KidKevi will do thank you
@@JoseGomez-fy4sh also that noise could be due to an exhaust leak that seals up once things heat up and expand
@@KidKevi thanks for the info I’ll have it checked out
@@JoseGomez-fy4sh Did you ever find the cause? I have a similar sound exactly as you describe in my LS3 C6.
Even on brand new rocker arms? Melling rocker arm mr-1341
As soon as it starts I hear it.
Do they have a brass bushing trunnion kit ?
@@KidKevi man I’m not sure I’m not finding anything that says there is or isn’t
@@dawson_performance well why don’t you pull the valve cover and check ?
@@KidKevi when I make it home I will. And will give update Been at the hospital since yesterday
Sounds like an LS1 not LSX
LSX as in, parts from every LS engine produced haha. Frankenstein of an Engine
Michigan motorsports bronze bushings do the same crap, just avoid them, use che or GM original rockers or btr tk001 or 002 units
I suggest not using bronze at all , any brand. I would suggest using the 8620 caged style and that’s it !
@@KidKeviafter seeing the review on the Michigan Motorsports bronze bushings, I'm going with the GM Original Rockers for LS 1, 6, 2, 3 for now then later take the bronze bushings out of the other rockers and put in btr v2 tk002 bearings.
Should have bought a ford😅😅😂😂😂
