I would think that someone has been in that motor before. They probably tighten down the rocker assy when it wasn't centered on the LMAs.

looks like they were overtightened the rockers and did that.

just curious, he orderd new ones already but it just dosent seem normal.

wow I've never seen the LMA's look like that and my head has been in and out atleast 5+ times. I would get new ones just to be safe. :up:

I have been into a bunch of A2/Z3 heads and have never seen a set of LMA's look like that.

And unless the rockers had their pins engaged and the assembly locked together, i cant see any tightening sequence doing that, nor having the tappets too tight.

My best guess would be that the LMA's had the pad wear enough to where the LMA came partiually out of the bore while running, but that too is a stretch.

would smacking the rev limiter to many times and over revving through mishifts do it? I know typically that will affect valves, but can it have any effect on that. I never seen that happen, didnt realize that those could be damaged like that, didnt know it was possible, wow.

 

[Sab]

im still shocked too, the motor ran like a champ

geeze i dont even know what would do that .. ive never seen anything like that
