Rebuilt block last september put rough 300-3500km on it , no smoke on startup never had a issues with cold or hot starts its a half bridge not over ported into oilcontrol ring path what so ever
after storing the car over the winter. It now puffs smoke on start up but clears in 5-10seconds holding rpm at 4k yeilds no smoke what so ever,

Only reused peice in my build internally was oil control casings the orings are brand new! So what happend?

s4 irons s5 rotors fd oilpressure reg front main bearing oil mod thats it

 

smoke can be from coolant as well, oil has a light blue tint, coolant/water will be puffy and white like a cloud in the sky.

 

had turbo manifold off last night and could see oil in both housings

And i will say it doesnt smoke what so after start up

 

did you use some generic kit you found like those ******** selling red silicone oil seals? because those are NOT the right seals.

viton and HNBR do not come in red, HNBR is green and chemical resistant viton is a matte black. glossy black seals could be nitrile or buna which are also the incorrect material that some of these asshats are passing off on people.

extremely worn irons will also allow oil to leak down when the engine is off, which is probably what you're getting, in which case just run it til it craps itself.

edited last line ^

 

Block burn oil if any before rebuild irons where with in spec if wernt i would have gotten lapped

And it should have leaked last year too not randomly after winter storage

 

then how bout this, it's a rotary engine, a little puff of smoke for 10 seconds once a day should be the least of your worries.

 

Haha yes this is true, i appreciate the insight appreciate the quick replies!

 

Usually Bad oil control rings seals will cause terrible smoking at high rpms under all conditions, warm or cold. The symptoms you described sounds like oil leak down and could be from worn side housings.

 

So tear down lap irons should be good?

 

the viton seals have a tight fit to the rotors and do not spring out as well as they should, sometimes the rotors are in such a position that a little leak down is normal. it's a compromise versus using the craptastic OEM seals that do not seem to last as long as they should.

besides, a little extra oil for the apex seals during crank has never been a bad thing.

 

and its a rotary, its SUPPOSED to burn oil

close this redundant thread

 

Nothing redundant in asking questions i have about a teaspoon of oil in each housing it didnt have any last year before storage so please dont be rude lol

 

Wasn't trying to come off rude, just joking around

In all honesty, save yourself the hassle and $ and drive it until it needs rebuilding again

 

Just sucks starting it at a car meet or show and pufffffff lol... Smoke well i guess i just blame it on cause modded rotary 🏁💁 lol
