Lash IS set.

Is it normal to have a little side play on the rocker ONLY when it is fully closed?



When they open even a little the side play is gone.

these are full roller rockers.
lash was set to .035 per gatermen. I did use a dial gauge to set it.

Also I set each cylinder while at TDC verified by both pushrods being as short as possible. I know most guys will do one at a time per EOIC

 

Yes, although the definition of "little" can vary....

 

It also depends if the lifter has been deflated of oil due to sitting over on the nose of a cam load putting full open spring pressure on it vs another lifter not seeing that same load or being slightly pumped up still. If the lifter is pumped out of oil you will only feel the lifter internal spring pressure due to the preload you set. Your guideplate is mostly in control for this wiggle room. In a setup like above you are adding so much mass to the system I'd prefer to just run stock rockers whenever possible, I suppose you can compensate with more spring, but the beauty of LS pushrod engines are the simple and light valvetrain that is very stable for a hydraulic pushrod system.

 

You’re using the term lash, in the place of preload…am I correct? This is a hydraulic camshaft? A little side to side rocker play is normal in that regard.

 

Thank you !
I did mean Preload.
It is hydro.

 

I thought i uploaded the video

 

I opened a can of worms with bronze guides. I’d prefer the stock rockers myself I already had BTR upgrade kit on my shelf but sprung for some heads from Texas speed and the whole bronze guides thing. TSP says stock rockers are fine but I have my doubts. Just a giant can of worms I never intended on opening.

 

That play is normal at rest. You have roller rockers in the video…are you changing to stockers? I’d 100% stay with the roller tip rockers ESPECIALLY with bronze guides.

 

If you are wanting roller tip rockers look at TSP or Yella Terra.

 

I mean, I appreciate you saying that I guess, literally I already have rockers. They’re made by comp cams and have a lifetime warranty. If anything wrong with them it’s certainly not aluminum which on one hand would be nice. I’ve seen a lot of threats about those breaking too.

 

thank you for the clarification that it is normal. I am 100% staying with the roller rockers because of the Bronx dies. You know how it goes one thing leads to another lol. Less ladies roller rockers popped up for sale on marketplace so I got a really good deal on them.
