Any one have any trouble out the AC oil filters? Fired up my 406 yesterday (cold day). I got some heat in it and pulled it out of the barn and into my shop looked down at the oil psi and is showed 20 psi "holy Poo" :cry: , I shut it down, checked oil, looked good, pulled the filter and put a new hastings on it. I fired it back up and it is back to 60 psi
