Smoke out of exhaust after letting off the throttle
2 Attachment(s)
The car is making good power on the dyno yesterday, but there was smoke out of exhaust after letting off the throttle. The tuning guy say it might be the vss but i have new set of supertech vss instilled when i rebuild the engine. Maybethe head gasket? or the Turbo? https://www.miataturbo.net/attachmen...ine=1439409621

Oil, coolant, gas, or butthole?

Check turbo for shaft play.

Built motor? It sounds like blow by.

Valve seals.
|
<p>My money is on turbo seals.</p>
|
turbo seals or valve seals.
|
Valve seals. Only under vacuum (i.e. let off) points to those over turbo seals.
