I would have to pull everything apart. They gave me a box of parts. I put them in so they wouldn't be in those boxes till I got off the road. That's when I noticed the pistons were not right. I haven't been home long enough to do anything for a while. I was a truck driver and stayed gone for a long time. Only had 3-4 days a month home s and was moving a couple days after I brought the basket case home.
