Hi All,
When doing compression tests in the past I have always removed all the spark plugs at the start and then tested each cylinder in turn. I mentioned this to a mate recently and he told me that you should only remove the spark plug from the cylinder that is being tested and leave the rest in situ.
Who is correct and does it make a difference?
Thanks in advance.
Paul.
