I got a 87 D250 with the 5.9 need a new set of lifters they are hyd flat tappet
I don't know if i should just go with off the shelf melling lifters or ?

 

That should work fine...

 

Are you changing the cam ? Get a kit !!

 

well ran into bigger problems :/

 

What might that be....

 

Let me guess, flat cam?

 

looks like maybe at one time a pushrod went through a rocker arm found a piece of the metal laying next to a valve sping also found a carter pin from the carb linkage sitting in lifter valley. I pulled engine out and apart no timing cover gasket just silicone bearing look to be wearing unevenly? Some left a frost plug in between the cooling jackets of 2 cylinder walls. Short story i just picked up a 360 from a 74 sportsman camper with 61k on it

 

Was the cam flat? Or was a lifter the problem?
Glad you got something to stuff in it for now...

 

cam looked good numbers checked out as a replacement cam and well ran into some more problems with the other motor now :|

 

What was all wrong with the original motor? Is there a chance you could freshen it up?

 

Dang, That sucks... So How are you going to get it up and running?

 

well what i thought was wrong with other motor isn't as bad as i thought has a burnt exh valve and rear manifold stud is broke off in head from previous owner.
I'm installing a new full engine gasket set/double roller timing chain/oil pump/water pump and running it lol.
