additional infos. on the 1.25 rocker arms.
we got them installed with a preload 1.5 turn after contact. About 3k miles
later the lifters became noisy when the engine is warm.
Bring it to the mechanic, he inspect them and tell me this. The set of 1.25
rocker arms came with valve lash caps, after about 3K miles the valves lash
cap settle down and the preload became *LESS* than 1.5 turn. So... we
should give them 1.75 to 2.00 turn when after contact on preload to prevent
this. In conclusion the 1.75 or 2.00 preload will be 1.5 later.... It's not
a defect, it's normal, similar as you do a break in on a rebuilt engine.
