Honestly, I'm still hoping it isnt, but to answer your question i really have no idea.
It makes wierd sounds compared to my old motor. I hope those will go away. But it runs.
The dumb part, i only compression tested 1 cylinder after the initial 3 times, the single cylinder was tested with my injector in it and hit around 300psi where as with the old injector it wouldnt hit 100 after 3 times. So my idea was to say screw it and run it anyway since i had invested 9 days and roughly $650 into the motor already.
But it is running just like the old one besides all the off noises.
