just collected!
They said that all is very good. will get a little smoke on start up for a while whilst last residual oil burnt up, but all emissions are good, and no damage any where.
They've had far worse before.
They think because my rev's were low when the event happened.
new AOS, new plugs since old were non-spec and fouled, throttle cleaned out.
Apparently I have a sports exhaust manifold, so that made more work to remove the plugs.
