Exhaust side smells like burnt popcorn, at idle the interior smells sweet.

Milled head around 11.8:1 compression, with Comptech 4-2-1 header, Spoon N1, 16 degrees timing at the distributor, B&M fuel modifier bumped to 52PSI, everything else stock. B18C5 motor.

Never like this until I started modifying.

Any ideas? Possibly a high flow cat is in order?

umm.. maybe u left some kernals in the engine bay.????

 

burnt popcorn?? wtf?

 

Mine smells like sulfer after a WOT trek into VTEC.
Other than that it just smells like chicken salad around town.

 

burnt popcorn is probably just a lil oil burning

the sweet smell though u might want to check out ur radiator cause usually a sweet smell is radiator fluid

 

What you're smelling is burning Rice. LOL

Seriously though, when one of my ricer friends put a huge can on his Civic, it smelled like fried doughnuts.

 

lol

 

kettle corn adds more hp and smells sweet!

 

Edwin, my exhaust smells after use as well... I thought it is just because the unit is new. If you want, come over, take a SMELL... if it’s the same odor then it’s the exhaust and not the monster you have camouflaged under the hood.

 

A sweet "maple Syrup" smell to the exhaust usually indicates your burning coolant.
The popcorn smell on the otherhand....?

 

my type R smells pretty bad after some exercise too!

 

sweet=coolant. Heater core or headgasket???

 

As many people had already said, sweet = burn coolant.

 

Thanks for the replies guys, I will have to check all the fluid levels tomorrow to rule those things out. No leaks anywhere to be found.

 

does it taste like popcorn too?
