ok guys help me out i have a jdm obd1 DOHC ZC that is boosted i check the compression and its 100 all the way across i dont understand but it runs fine and still pulls pretty hard what do you think is the problem, headgasket? and i also tried putting some oil in the spark plug hole to see if it was the rings and its the same compression PLEASE HELP

 

valve adjustment? New pistons? New motor?

 

it is a pretty new motor i got it from HMotorsonline

 

The motor runs really strong tho i dont understand that
