Do i need to check all 16 when using johnsons lifters? And when checking for exhaust valve do i turn the motor clock wise also until the intake rocker goes down??
I'm doing a head gasket job on an 07 Yukon Denali 6.2l. I got the heads on and now I'm doing the Rocker arms. I noticed when I'm torquing the arms some of the rockers slide from the center of the valve stem and moves closer to the edge of the spring. My valve springs are slightly compressed also when I finish torquing to 22 ft lbs. Can you tell me what can be the problem? I'm stumped
1st time measuring pushrod length here, but I have a question see if anyone could give me advice, I basically did everything like he did on the video even the math but with my measurements, so my intake is 7.2875 rounded it to 7.300 and my exhaust is 7.325, should I buy all the pushrods 7.325 or should I buy half and half?
Thanks for the info building a 6O in a C5 Texas Speed heads has been a nightmare 7.4 push rods but dont think the mechanic did the math or put the pushrods on the small lobe of the cam going to a performance shop today......
Extremely informational on this, I did my first cam on a gen 4 6.0L and the pushrods were doing my head in with the ticking and not knowing the base circle had changed. Big thank you from a dumb ass trying to get his engine right, and extra points on background tracks!
Yes you add it to whatever preload you need. Most lifters such as Johnson lifters will have a specific preload on the box. GM lifters have a much broader range and are more forgiving
yes. for the first method you have to add it. the second method (the turn method) accounts for the pre-load. I second what @Brandon Ouzts said - GM lifters have a really broad range. as long as you're in that range you're good. hope that helps!
Big thanks for taking the time to clearly explain this process. The other videos I’ve watched have been confusing.
This is the best tutorial I have found for this procedure

When checking measurement do you tighten all the way down or just finger tight

Hopefully I can figure this out now
About to build my LS swap and appreciate the video!
I always torque the Fastner to spec then check for zero lash
Great stuff Brother!!!! Thanks!!!
Thanks,some good info.
Great video, I like that you described it clearly in both methods.
Thank you!
Really helpful video 👌
Glad it was helpful!
did you add pre load to you length or did i miss it?
