this bit is strange... thats a Shit load of oil to lose in that amount of time unless you were doing warp factor 12..
are you sure it hadnt lost it before? or had it serviced recently and he forgot to top it up? was there oil in the exhaust or covering the trailer?
any noises apart from what your missus heard with/before smoke? any sort of signs? loss of power?
any rattles or noises after starting again with the oil top up in it?
I am ignoring the so-called COVID experts as we have always kept well within the rules and been especially careful. We got a lot of funny looks down at the shops as we were the only ones with masks on and walked out of several stores where the social distancing was not up to scratch. We had planned to do bush camping for the entire trip.
Back to Bird's points.
The 5,000 km service was done 1000km ago and we don't burn oil between changes.
My mechanic is a Landcruiser man with his own 200 Series who has done our work for many years. He did a super big service at the end of March in expectation of our lap a few weeks later. The low mileage since then was a consequence of us staying at home.
I had put the POWER button on to gun it up some uphill overtaking lanes in S5. But it blew on a gentle downhill slope.
No oil on the van or the Stone Stomper. Just grey-white smoke and plenty of it.
After putting a few litres of oil in it had oil pressure and no smoke at under 1500rpm with no engine knocks. Mind you, we only gave it two 30 second runs before it went onto the tilt tray.
It sounds turbo related to me.
