going to pull the vavle cover off and try changing out the pedistal i know the push rods will rubb on the factory one but its for test only to see if i can touque it and get oil flow if it dosnt fix it i am going to return the 1.9 zzp rockers . maby the heads wear milled down some time in the engines life who knows ..
i always thought the standard mod'd 1.9's were for an L67 motor....i know all the rockers and pushrods are the same, but i dont know why they would sell these if there wasnt a reason...
on zzp's site they sell an "ER" rocker set- http://shop.zzperformance.com/store/p/251-ER-Ratio-Rockers.aspx
there is something that is different but i'm not sure what...

ok i tryed the stock pedistal wont work 
push rods hit the pedistal
so then i tryed stock rocker arm bolt
same problem no oil.
so one last thing to try was to try switching push rods
so i pulled all the push rods out and found the one that was not pumping oil looked newer then the rest so i lined them all up and pick the shortedst one and put that with the rocker that wasnt pumping oil and yes it pumped oil
looks like the push rod was slightly longer and wold not work with that lifter for what ever reason so now they all are working as should... makes no sence becuse i didnt pull out push rods when i put new rockers on ..........
yes there is slight tapping noise i can live with that
i just want to say
thank you to every one for there help

are you running the motor with the VC'ers off checking for oil flow or are you looking for oil to flow as the plunger gets compressed?
oilflow through the pushrod is controlled by the metering disc which only liftsto allow flow as the lifter/valve closes towards the lobe base circle, so the only way to know for sure that you have oil flow is running without the valvecovers or pulling them imediatly after running for 2-5 minutes
the only reason you saw "oilflow" was cause you left the pushrods in and hey probabl didnt completly drain where the one may have drained out, the inside of the pushrod holds a pretty good amount of oil...enough that emptying the whole lifter plunger bore/valve into would probably be just barely enough to fill it up.
pushrods have uper and lower wear patterns, the bottom with have a polished ring from the lifter cup and the top will often have striations from the arc of travel of the rocker cup, do not flip em upside down as this will not let the bottom seal..if your worried about how worn some of the upper ends an become then buy a new set of oem
all 3800 pushrods are the same length (when new, worn one's can vary quite a bit) except for the SI motors which are 1 inch longer
that said lifter accumulate quite a bit of soot/carbon over the lives that can settle onto the checkball and oil metering disc, if they are in good shape its ot a bad idea to pull em apart and clean em out with solvent and blow em dry to ressemble.
its also a good idea to point the oil inlet hole towards the pass side for bank two rear) and the drivers side for bank 1 (front bank) as thats where the oil flow comes from as it travels down the bank2 alley through the rear cover towards the front galley
