Well I had a weird issue at the plane this weekend. I went to get everything ready for when the new exhaust shows up, I found that the #1 cylinder (left rear) intake tube I could rock back and forth slightly at the upper flange. So I thought maybe the gasket was bad, took off the two bolts, installed new gasket and torqued to specs, still has movement and all others are tight. Any ideas what could cause this. I see there is a swaging tool to expand tube at lower edge but cant really find any info on the upper with movement. The engine is an IO360C1C in a PA28R200 N32552. I know I will need to have my A&P over but just looking for some ideas. Don't see any cracks or dings anywhere. Thanks Again
