Review of Mishimoto Thermostatic Oil Sandwich Plate

Edit: the one in the video is counter-bored correctly so so long as yours looks like that than it had to be an assembly error(unless the counter bore is the wrong size). In the video at 0:45 that is what your' plate needs to have on that hole. I had one of the first original defective GTM kit's that had issues with the lines and my motor popped. I shut it off right away, removed the plate refilled it and drove it while i was getting replacement lines and my motor started throwing timing codes a month later because little pieces of the thrust bearing where plugging the oil passages to the cam actuators. You may not know your motor has had it's life shortened right away. (as a side note you saw how effective that factory oil pressure light is didn't you lol useless)
