I'm quite certain that the lifters and the rocker arms are one piece on the KA24e engine. At least they are on my 90 model. I tried to buy lifters only and you cannot, because they come pressed into the rocker arm.
lifters are sold with the rocker arms (on the KA) there are 4 different styles in the that engine, so unless your going to replace them all you'll have to determine which style you need (should be a "E" or "I" and a number stamped on it) here are some numbers...
13257-40F06 intake/frt (4)
13257-40F07 intake/rr (4)
13257-40F16 exhaust (2)
13257-40F17 exhaust (2)
see if that helps....
Thanks, I would like to just replace all of them. I still have yet to find a place that seems to carry all of them. I don't want to order from the dealership, since I think they may be quite expensive.
