Hi All,
When performing my annual I discovered some rubbing occurring between the bottom of the crossover exhaust pipe from #4 and the top of the Y pipe that combines cylinders #1 and #2. My RV-7 setup is a stock standard IO-360M1B Vetterman Exhaust supplied by Van's, with 168hrs airtime. There is only about a 1/8" gap between the two pipes.
The questions I have are as follows:
1. Am I the only person who has observed this issue?
2. What is the standard clearance between these pipes?
3. What is the standard procedure for ensuring the minimum distance is obtained (shims, re-bending tubes etc).
Not keen on a 1400°F gas blast within the confines of my engine bay, I am looking at purchasing and fitting new tubes at this stage.
Cheers.
Tom.
