I aquired a D16Z6 Head in great condition with an OBX intake manifold sans the Vtec Solinoid for some PC repair work last night, and my engine is leaking compression like all holly hell.

Couple of big questions here:

My car is a 92 CX Civic that has a 16 Valve Head swap with a P06 ECU, 91 SI cam, and I/H/E

The car when doing the compression test Crank once 40, twice 80, third time 120, and immediatly after hitting 120 it starts slowly dropping off untill it turns over again.

While Driving the car, at nearly 4K RPM it suddenly begins to pull strongly *I'm assuming this is because the Pistons spinning fast enough to hold constant compression*

Car burns maybe a quart of oil between oil changes.

The 16 valve head I had put on the car Had pitted Valves when I had installed it to begin with, and appeared to be, and was most likely off an abused/high mileage engine, and my block only has 98K Miles on it, and was bought new off the lot by my father *Not beat on*

In the past 3 months since the headswap was the power has been degrading, and the leak getting worse.

with all this in mind, would you pretty definatly say the head is the problem and is fucked and the valves are leaking, or is there ANY possiblity this is my piston rings as I'm burning some oil and I had Popped the headgasket over a year ago back when it was still an 8 valve???

You running 120 across the board or only with one cylinder?

across the board

Bumpity, Could really use some confirmation here, can't afford to waste money on the head if I need to do the block too.

Bumpity again, I got my headgasket and Timing belt and the solinoid should be on its way, need some honest opinions here.

You probably have a leak in the headgasket. Rather unlikely that all 4 cylinder ring sets are bad.

Though it could be a valve problem too if they're not seating properly.

I'd say headgasket first though.

Headgasket is less than 3 months old, can it really go bad that fast?

That and also It's not burning any coolant, when the headgasket popped on the origional head it was spewing sweet white smoke, and the oil was cloudy. Oil is dirty, but no coolant in it and its been 3 oil changes since the head popped.
