Dear friends,

I want to know more about engine. For example, if the piston ring loose or (makan) already, will the compression of the 4 pistons in different reading? Just want to make sure cause some ppl said the reading wont be same and some ppl said the reading still the same. Very confussing. That day I sent my car to do a compression test at AMOIL. End up the reading for 4 pistons is the same. 12. Thats mean my piston,block, & piston ring is ok? Right? ;)
