Sad day for my ve30de turbo

This was while still warm? Or on a cold engine? They actually don't look that bad in the sense of being pretty consistent - but honestly they're about what I'd expect to see on a cold engine or if not opening the throttle all the way during the test.

While I own a 4th gen car, I noticed your post.
Was the throttle floored while you were taking the compression readings?
On other old cars I've worked on, valve adjustments were done. I know that the 4th gen has adjustable valve lifters, I expect that 3rd Gen does too.
Adjusting the valves might help increase compression. Unless they are burned already.
You should consider having a compression leak down test done. It will identify whether compression is leaking through the rings, or through the exhaust or maybe intake valves.

did it with engine warm up. drive good still but i feel the power lost. also did the wet test a year ago and piston rings are worn down. compression was better a year ago. its time for rebuild anyways, engine has over 230,000 miles on it. and still kickin
