Exhaust smells like paint

Odd one for you. Recently more and more on cold startups I notice my exhaust smells like paint. Any ideas???

 

Is the exhaust tip painted?

 

Are you sure it is not coolant/antifreeze smell?

 

That usually smells like maple syrup

 

Not painted. Stock tip

 

All of them have that weird smell,until the truck gets up to temperature.Its more noticeable if are parking in a garage,some of smell is also the winter blend gas.

 

Is the check engine light on?

 

The alcohol in our gas in the northeast has an odd smell, but its normal.

 

I was thinking winter gas. Don't remember that smell in the past though!

 

Could be a new environmental additive required by federal or state laws.

 

Winter blend gas and additive packages Do smell odd before the catalytic converter is up to temperature and aiding in the burn-off.

 

I know this is an old thread, but I started smelling the same a few months back. My truck has been in and out of the dealer trying to figure it out. Coupled with a weird brown residue on the oil cap they're thinking it's the motor on the way out. Luckily I've got a few more months to my warranty, so I'm making sure they get this taken care of. My service manager thinks I have enough to get a new motor possibly.

 

You dont give much detail.....

What makes them think the motor is on its way out?

Brown residue on the oil cap is not unusual. Most likely with high mileage vehicles driven short distances.

 

What does the oil on the dip stick look like? I'll wager you have a coolant leak into one of the cylinders.
