Update: Just did a leakdown test on cylinders 1 and 4. When the car was at TDC, there was a lot of air coming out the mufler and a very little coming out the intake side (bov line). The intake side was only noticable when put up to my ear or lips. Not really noticable by hand. The exhaust was another story. I could feel it with my hands over the 5" tip. I also put a bag over the muffler to see if the bag felt the pressure and it bulged quite a bit
. Looks like I will be without a car for another few days.....
