Exhuast leaks at the slip joint?!
RV-4, O-320-E3D with mid 90's design Sky Dynamics Crossover exhaust...
The exhaust system has short stub pipes that bolt to the cylinder that's maybe 5-6" long and then slips into the next piece which starts the curve and crossover. I've started to get some blowback or leakage on the slip joint on the #2 Cylinder (Front Left). I can see discoloration on the #2 intake tube and plug wires along with the obvious staining on the pipe itself.
All bolts are tight holding the slip joints in compression but there is still a bit of wiggle where I can sometimes, but not always, rock the joint back and forth (maybe 2-3 degrees of movement) which I'm suspecting is the leak.
Anyone dealt with this before? Thanks in advance. I'll try and grab some pictures tomorrow if it will help.
