Blue smoke?

[Tim Oldland]

Is it normal for the RX7 to give out a little puff of blue smoke on startup?  

It doesn\'t happen all the time, only after its been left for a couple of days....

I\'m new to the rotary, so i need to know these things!


Cheers,

Tim

Hi Tim,

This is normal - the rotary uses oil (as you\'ve probably noticed) injected into the combustion chamber (provides compression and lubrication).  This is a small amount and is burnt off in normal running.  At startup there is a little extra in there to burn off so it smokes for a short while.

Yeah, completely normal as far as I know. I wouldn\'t be surprised if the oil injectors seep a bit into the rotor chambers when the motor is shut off. You should\'ve seen the sh*t that came out of my exhaust after 10 months of storage!

Cheers guys, that\'s put my mind at ease.


Oh, and Iain, i\'ve got a shiny new 12x3" plate on the front now, it looks way better....

Should have a higher vmax now then without the old \'air brake\' on
