For starters me and my dad went in half on a 1991 honda civic hatchback, interior was in really great shape and we got it for 600 bucks. The original owner said one day the engine just died.
We towed the car home and the first thing I done was a compression test.
All four cylinders are 0. I dropped small amounts of oil in the cylinders, still 0.
My first guess is valves, but I'm really not sure as i've never went thru this process before.. I believe it's DPFI and the engine is a D15B1, I'll verify here shortly.
Any help from you guys is appreciated

timing belt or somehow all of the valves are way out of adjustment or bent or burnt or something of that nature. no unusual noises when cranking?

I just posted so maybe I could get an idea if this engine is trashed or not, If i could slap a head on it that would be great, but if i haft to find another engine no big deal.. I've found one for 225 locally.
This, or is the cam broke. 2 years ago I bought a 1990 4 door civic with a broke cam right down the middle. Took a while to diagnose no spark because the last thing, I though of was is the cam even turning on the distributor/rotor side of the engine.
pull the VC off and see whats going on in there. check vlave lash, crank it with the VC off to watch vertything move. also pull off the radiator cap as you crank and see if there are any bubbles coming out there.
Maybe your gauge is broken? Try it on one cylinder of another engine. If it works then you either have bent/burnt valves or holes in your pistons. I would lean towards valve but at any rate the head would need to come off for inspection. Its possible the timing belt is stripped but has enough to turn the cam and it has bent the valves.
Jimmy I have a z6 and a hydro trans z6 trans. I also I have an a6 cable trans. I may have a a6 short block to I'll have to check at the shop. Text me if you need any of the parts or need help with the car. I'd be happy to come put my two sense into the car. LOL
checking the gauge is a good idea, also put ur hand over the oil cap hole while cranking before you pull the VC off to see if the rings are letting the compression leak.

If you've got something we could put together for around the 200-250 range, i'm game.. I would love to get this car on the road very soon so I'm not having to daily drive my integra.
From my understanding it's going to take some wiring to swap in a d16z6..?

You gonna track this car or are you using this car to get the Rs off the road?
Newtron our location is the secretest of secret.
I'll give you a hint though. If Lane Kiffin ever comes back to our town I'm pretty sure he'll be set on fire.
