I'm looking at a car right now, and I know the compression test results, they are the same across each cylinder, but I was wondering what the numbers should be, and what would be the problem if they are too high or low...
btw each cylinder reads 140...
What is a good compression test for the KA24DE?

KADE #s should be 179psi "standard", 151psi "minimum", no more than 14psi diffeence across all 4 cylinders.
Warm motor, throttle held wide open, fuel pump disconnected, good battery, minimum 300rpm.

It "washes" the oil off the cylinders and causes progressively worse readings as you go down the line...i.e. #1 may seem OK, but #2 will read lower, #3 even lower, etc...typically.
You can't gain any info from a comression test if it was performed impoperly..you have to repeat the test to know anything.
