Random plume of smoke!
Turbo Mini Forums

Chaps,

Done around 600 miles now in the mini. Today when sitting idling in traffic after a 60 mile journey (120 round trip) it just started chucking out a fair amount of white smoke. Enough to not see the car behind!

Gave a it some revs and boost and its cleared, not come back after trying to replicate the scenario.

There's no oil in the inlet, compression check all good 150+ on all cylinders.

Oil return is nice and large, 17mm minimum and downhill all the way.

Oil was around half way on the dip stick.

The turbo, was rebuilt with a rebuild kit. I'm thinking the issue is probably in this area?
Unless anyone else has any ideas on what it could be? Or could of been?

I'm leaning towards just buying a Chinese gt17 eBay job and putting that on and getting mine rebuilt properly.

Usually this sorta thing is excessive blowby or turbo drain backing up or early days of turbo failure.

check the oil pressure,

could be the turbo ? those chinese gt1752 turbos are very good, built a number of engines with them and they are very reliable

Thanks for the suggestions :).

I think I've found the issue. Took it out again this evening and it only did it once after about half hours driving. Coasted down a hill as I stopped and let it idle it started smoking, rev'd it up and it stopped.

When I got home I noticed a drop of oil off the bottom of the breather on my catch can. The breather was clogged with oil it took a good blow to get air through and had a fair bit of resistance. Cleaned it and now it's nice and free again.

I think in the long run I need a baffled catch can or vent it to atmosphere.

I'm yet to try it on the road but pretty positive.
Oil pressure seemed spot on between 20psi and 60psi.

Jonny what stat are you running?

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

I'm running an electric pump with a controller, so I have no stat (just a sleeve fitted). Just set the temperature you want to achieve and the controller does the rest. It also controls the fan.

What's the controller set at?
