Default Why am I smoking?

Watch the video and please offer suggestions as to why I'm smoking.

Tubbo Smoking

(it is a little hard to see in this video because I shrunk it down for the web, so you may have to kind of pan back/forth to see the puffs - thanks)

Is your A/F ratio okay ?
Also, are your engine running hot ?

No cat or muffler.

A/F was rich at last dyno run (March?).



The engine is running cool, perhaps too cool? It barely reaches the first tick above the double tick. I assume this is where the thermostat opens to the cooler. I have double coolers (no ac condenser) so I assume the thermostat opens/closes/opens/closes...

Pull the rubber inlet boot to your turbo... See if there is any oil present.. Have a leak down done.. Broken ring/guide wear? What turbo are you running?
