Well to start off with im new to the site and not all that knowledgeable about DSM's. This is my sencond eclipse after i sold the first one i vowed to myself i would never get another, but vows are ment to be broken right??
Anyways so i recently bought a 1g gsx off my friend, who bought it five years ago as a project for us, after the project went foul it sat for the last five years.. The original problem with the car was a burnt valve, After hiring a "mechanic" to take the head off and have it taken to the shop and have it fixed and then have him put it back together. which was all done the car would never run again, i know it ran before being pulled apart because i drove it back to the house. So after my buddy took it to a shop and they couldn't figure out anything with it, it just sat there until one day i decided i needed a project!!
Well i bought the car and had it towed to its current location, I replaced the plugs and wires because they were bad and brittle, I could not figure out why it would not run, so i rented a compression checker, and found there to be "0" compression on all 4 cylinders, i pulled the head and found that all the intake valves were bent. Which sucks because that head was just rebuilt from the machine shop!! the guy who put it back together timed it wrong.. Anyways i got my hands on a used head, and put it on the car, timed the car and tipple checked it, and it was running really rough, i figured out the gap on the plugs was to big so i corrected it, also i found out it was lagging really bad because the intercooler tubing was leaking. But After fixing all that good stuff the car is still running crappy, so i decided to do another compression check, and found cylinder 4 to have "0" compression??
Im not to disappointed about this because after 5 years of sitting and this being my first time actually working a dsm in this situation, and it actually starts up and runs (not good, but runs) im happy with that, if i gotta tare it down again i guess it will be easier the 2nd time,
This is my first turbo car and my first time really doing anything major like this to a Mitsubishi, I had replaced my timing belt and clutch on my 95 rs, but never taken the head off a dsm or anything in that nature. Is there some other reason why it would have "0" compression in cylinder 4, Beside bent valve or piston rings?? But even if it had bad ring on that cylinder shouldn't it read some compression? Or did my first time taring into this dsm fail horribly?,
Do you guys have any suggestion, or any input on what it might be or what i should try to do??
Sorry if this has been covered i searched the site and didnt find anything but lots of other helpful info, Also sorry for the long post!!

After valve contact to your pistions did you replace them? Its not really going to make low compressions but run bad none the less when there is valve gashes in your pistons...
I guess you have to ask yourself how far you want to go. but seriously look into doing the bottom end refresh.
