D16Z6 Block, Which head & Pistons model should be used?
Got a 1993 Civic EX ( D16Z6 ) Burns very little oil, Planned on taking out the engine and replacing all the bearings & seals. Getting new rods & pistons. I did research myself & found my suggested pistons & head.
Pistons:
I find P29 & PM7's to be most logical since their dome ( High compression ) pistons. P29 would be my first choice, their more common in choice it seems.
Head:
PM9 ( JDM D15B V-tec head ) I hear is the same as the P08 ( D16Z6 ) head just has a more aggressive cam. Also I hear theirs few different styles of the PM9 ( ?1stage - 3stages of vtech? ) Which with the D15B 3 Stage V-tech head is supposed to be like 30+ hp. Hence the car its from ( EK3 ) has 150HP so I hear.
I cannot be sure, I would like your help. What is the best set up for a D16Z6 block?

first of all if the car is still running i would do a leak down test to make sure what causes burning oil
its not a hard thing to do so figure that out before tearing it down. could be worn rings, or bad valve seals, or bent valves or bad valve guides so u might want to replace all that too.
the d15b head does have a better cam but for pistons it would depend on which route you wanna go
all motor or force induction (turbo)
so when you figure it out then good uck

You have a cracked head or a blown head gasket. Oil in the coolant comes from the passages ni the head seperating oil gallies from coolant gallies. If your rings where bad it would be sucking tons of oil into your cylinder and burning a lot of blue smoke and then fouling out your plugs quickly. So you will need to determine which head is faulty. Even if it just a head gasket blown, you have the head off and it is proactive to have the head pressure tested and look at valve facings while you have it off. Simply pulling plugs will not always work. Because the crack or the blown head gasket mainly cross over from gally to gally and do not leak into the cylinder. If it was leaking into a cylinder you would be getting white smoke which is indicative of coolant being burnt in the engine.
