goto auto 1 or somethin like that and buy some oil cleaner, somthing that cleans all the gunk out of your motor, i done this a year back when my ef was doing that and it was fine for awhile, but they it turned out to be one of my lifters was buggered and i had to get them replaced.
too right there a better design!
on the old ea set, between the rocker and pedestal there is about 2mm of wear and thus making the lifter sitting halfway off the valve stem!!
i paid $100 for the ef set, 3 weeks later nearly and i havent heard i single tap!
With going from ea - ef style the blocks that hole the whole shebang up (theres 7 of them I dont know theright name for them) have a fifferent suystem for holding the rocker cover down. EA has a pole that comes up with a thread that the dome top nuts screw on to. EF doesnt have this - it has a long bolt that screws into the blocks. If you get some EF rocker cover bolts im pretty sure that wouldwork. Otherwise you have to either disassemble the whole setup and swap the blocks over OR get 2 nuts on the poles and screw them on a bit then lock them together and this will give you a way to unscrew themn and screw them into the ef set.
Also if its rattling while driving and still rattles after a new set then its either a vorn valve guide like on my car :( or a broken timing chain guide also like on my car :(
all i did to hold the rocker cover down was to take the studs out of the ea pedastals and put them into the ef set. worked fine.
im now thinking of getting a ef rocker cover and polishing it up nice mmmmm.
