    Do you have to remove the heads when changing the valve lifters?

    No, you can take off the valve covers and take off the rocker arms, then the pushrods, then take off the intake, and the valley pan and you should be able to get them out easily.

    Valley pan?6.2 diesel that was in pieces in our garage last year didn't have valley pan.If I'm not completely wrong,you have to take off the heads in order to change lifters.

    I'm too lazy to stick shift,that's why I prefer autotranny.

    I just doublechecked and according to the Haynes manual you dont need to remove the heads, just the rockers, pushrods, etc. To be honest ive never done this before on a 6.2, but I figured that there is a valley pan because you have the intake with the injector pump below it so I figured there is a valley pan to seal the lifter area. Now, I assume that if you take of the manifold and the injector pump and then whatever covers the lifter area after having taken the rockers and pushrods out you should be able to take the lifters out just like a gas motor. Im hoping some of the guys who have done this i.e. dieseldan could elaborate on this a bit more. Sorry if I have given any misinformation, Ill try not to let it happen again.

    On the heads there is holes where the pushrods come trough,but the hole is small,so the lifter don't fit there.Also,lifters are hold in place with retainer that is bolted to block,and bolts are under the head.I once tried to change couple of bad lifters,but then realized that I have to remove heads.Injector pump can stay in place,though.

    OK, I just looked at another pic and it looks like you describe, but then there is another pic that looks like a gas motor setup. Sorry for any confusion I have caused.
