Blowing smoke :( (With video)

Hi guys,

 

Completely at random and after a pretty tame drive, I got home and my Supra was billowing smoke. Apologies for the bad position of the video, I only had some grass to hold my phone up :p

 

 

Any thoughts? My first idea was turbo oil seals, but they were only rebuilt 20k miles ago by CR turbos. Still a possibility I suppose..

As it gets worse with temp and not better it is deffinately not valve stems. I would say turbo seals or rings but since the oil looks good and no smoke from the filler cap it is mostlikely a turbo seal. Good compression results would confirm this.

That is a lot of smoke.

 

Take an intercooler pipe off just before the throttle body. It might be blathered in oil in there if a turbo had gone badly enough to cause that much smoke. Is it making any weird noises at all? Misfiring?

 

I don't mean to be negative though.. but I had an MX5 that was like that. Turned out to be the oil scraper rings were fecked.
