Can't Be

There is no Carbon-Up on the Cylinder Head at ALL.

IT's been from the machine SHOP..

Even the Piston Head Was SHINY before i install it.

Everything Was SHiny.

SO nope. no carbon BUilt up..

Check it with another compression gauge before you go tearing it down again. Curious - why the rebuild in the first place ?

Usually, vehicles with hybrid engine has high Engine Compression, but as high as 240-246. Check your Engines' compression gauge before fixing it.

Needing to do a compression test on my hybrid and don't know what things I need to disconnect on the electrical side to keep from screwing up any computers or other electronics. Any help would be appreciated,

Isnt high compression good? You might get better mpg out of say premium gas. How do you do a compression test? Im kind of new to this.
