compression test?

[2L8V8]

hey guys i just performed a compression test on my 1jz
just need some help figuring out what this means
cylinders
1-145
2-160
3-165
4-165
5-135
6-145
now these are the numbers with the little bit of oil
1-165
2-165
3-170
4-160
5-130
6-145
i am only suppose to be in a 10 percent range right?

Iirc its like a 15psi difference between all cylinders.

Was this when the engine was hot? And with a good battery?

123 went up with oil that would be rings.

45 shouldnt have gone down tho. Thats kinda odd. 5 looks pretty low too.

Are you having any problems at all?

no the engine was cold and with good battery
last summer i done a single turbo upgrade and drove a little bit then i started smoking really bad and just figured it was my rings.
but now got the car into the garage and pulled my turbo off and the intercooler, my intercooler has oil in it and in my piping into my intake.
so i wanted to do a compression test to make sure my motor is still sound
there is no ticks or banging motor is still running good just smoking alot

thanks

sounds to me like the turbo is blown.
my 1j started smoking to, did a compression test and the numbers were very similar to yours, actually if i remember correct my number 5 was also around 135.
I ended putting a good set of twins back on an no more smoke. the car still pulls hard.
