Hi group,

I started my 04 Inspire today after 1 month of sitting in storage (indoors ) in the north east. I noticed that some rust blew out of the tailpipe when I first started it. Is this normal (due to age & 79k miles) or something to be concerned about? Has Anyone else had this occur & was it related to a head gasket or radiator issue?

My guess would be exhaust manifold and muffler rust caused by condensation

Gonna guess you had condensation in the exhaust that sat and rusted and you blew it out.

If that is correct, restarting after a shorter period should be rust free.

I started my motorhome 4 years ago and the muffler fell off due to rust. A little bit of rust shouldn't be a problem at all!

Hi,

Thank you for prompt answer.
Is this something I should be concerned about? Is there anything I can do to treat / prevent this?

Thanks in advance.

You could replace it with a stainless steal exhaust system.

The best you can do is make sure anytime you start it run until everything warms up completely. This will help insure any condensation evaporates.

Ray,

I respectfully disagree unless you mean to warm it up as quickly as possible by takeing it out foe a drive. Warming any internal combustion engine by running it at idle is the worst thing you can do. Corrosive acids condense out of the exhaust when it encounters the cold engine and exhaust system parts. While this problem can't be totally eliminated it can be greatly minimized by getting the systems up to operating temperatures fairly quickly. Diesel engines can take a long time coming up to temperature at idle so if you have to wait increase the idle speed.

This may have been the cause of the original problem if the owner is in the habit of starting his coach on a regular basis and letting sit idling. It is better not to start it at all then to do that when the coach is in storage.

Well said Don I should have been more detailed. You want to run trans up to temp also and pretty much won't happen idling.

The colder out the longer run should be. This same process pertains to gas engines also, they may heat faster but not thoroughly at idle.
