SO I think I got me a 12 valve that needs to be pulled apart and built up. I dont want to do anything crazy, just try and get it running again. I guess it melted the turbo so I need to get in and check out the pistons. I have been hearing about the different injection pumps and cannot get a visual picture of what they look like. He said it was one of the last 12 valves so is that a later 90s? I could mnaybe get a 24 valve, but id rather stick with the 12 valve because of wiring.
