KE Motor

[graham7773]

I just bought a 1989 KE 1.6l laser needing a motor for $100. I have also bought another 1.6l motor which looks identical in most respects except that when I looked under the rocker cover it is so clean it looks brand new. my question to anybody who knows is this. when did the 1.6 laser motor get hydraulic lifters? my dead motor has adjustable tappets and the extra one I bought has the hydraulic lifter/lash adjusters. Anybody?
