Hi, just got my DMC back on the road after a few years of sitting. The exhaust on the passenger side's gasket is leaking bad. I heard this hard to change... Is there anyway I could possibly do it without taking the engine out. (A definate impossibility) I also noticed that the air inlet duct the runns from the air inlet to the airfilter is missing. (Along with the duct for the heat stove) Is it going to cause damage to the engine to leave it disconnected? Also could i just replace it and bypass the stove completely? Any help is greatly appreciated.... -Dave
