Re: [Chrysler300] We're just fuming!

 Keith,
When I built my 300H I had the same issue with exhaust fumes entering the passenger compartment. After examining everything possible from the engine bay to the exhaust tips, I discovered the fumes were getting in from an improperly installed trunk lid gasket. I put it on backwards. I tried getting into the trunk and looking for light around the gasket but found none. The configuration of the trunk lip prevented this test from working. I ultimately cut strips of newspaper and laid them over the rubber gasket, closed the lid and pulled each strip from the outside. Where there was ample friction, the gasket was making contact with the lid. Where the paper pulled out easily is where the leak was. I removed the gasket and installed it correctly, made a few adjustments to the latch mechanism, and the problem was solved. Oh, and the water leaking into the trunk also went away. I'd bet money that's your problem as well. Keep us posted.

Regards,
Mark Souders

Here's a bit of a vexing thing I'm looking for an answer to.  When we ride down 
the highway in our C, we have engine fumes entering the cabin in such a 
concentration that it made Judy's eyes burn like crazy on the way back from Lake 
George.  Not enough to bother me that much, but she couldn't even keep her eyes 
open at times.  She was fine whenever she got out into fresh air.

It has to be crankcase blow by, but I don't know why it's coming inside - 
apparently through the heat system.  And BTW it's a non-A/C car.  The engine is 
freshly rebuilt, and there's no smoke visible coming out of the road draft tube.  
I also don't see any smoke at all coming from the oil fill tube.  So this tells 
me we must be getting a pretty straight shot of whatever is coming out of the 
draft tube if that is the source.  

Has anyone else had this happen?  If so, what have you done about it?  The only 
thing I have thought of trying is to clamp a foot or so of rubber hose on the 
road draft tube to send it further back.  That might work, but it wouldn't fix 
what's really going on here.

Any ideas for me?

Thanks.
Keith Boonstra
