A compression test is to see if the cylinder is with in specifications. In a compression test, you crank the motor over until the needle on the test gauge levels out. Then see the rate at which the air dissipates.
When doing leak down test you are injecting compressed air into the cylinder and then you can hear where the leak is coming from.

so if your compression test is good you do not need a leak down test

i think it is a injector in #7
someone told me it might be a lash adjuster but if the compression test is good i do not see it

check the timing. The tolerances could be off enough to only have one or two cylinders misfire.

right, It is possible.
