On the w/end I went to go up a short steep
rock formation without enough momentum (high range as
well) and the old girl started choking I waited for it to stall but I was to slow on the brakes and it rolled back a couple of chugs which surprised me as usually the compression holds it. Any way I braked and clutched and the motor was firing and not sounding right high rpm and generally sounding different so I turned it off and restarted and made the obsticle ok. I didnt think modern motors (2h modern?) would start in reverse is it possible?

Yes it's possible or you could'nt do a
hill start in reverse as I was show'n at
driver training.

You are kidding, right?
When you do a
hill start your motor is still running in the same direction forward or reverse. You transmision decides the rest. Bloke above is saying his motor fired up bacwards( wrong direction). I don't know if it is possible with modern motors.

Bob,
The way I read the question is, Will a diesel start and run in the opposite direction . The motor can sometimes run backwards, exhaust out the
snorkel and air up the exhaust.

Davoe,
Yes they can start and run in reverse. Black smoke comes out of the
snorkel and air is sucked up the exhaust pipe. If the motor does not run for long than I don't think any damage was done. It happened to a mate of
mine a long time ago doing the same type of
rock climbing.
I don't know if you would call a 2H a motor, but it is almost bullet proof.

A long time ago on a construction site we were running one of those Euclid Scraper Machines. I could be wrong but I think that they were two stroke diesels. Stalled the machine on a steep slope and released the clutch as it ran backwards and it fired up in reverse. Then we had 6 gears in reverse and one forward. Quite funny. Had to crawl up to the top of the incline and then shut everything down and start again.

Yup 2 strokes were very famous for it back in the 70's and early 80s...

Dont know about modern diesels but on the old
sydney ferries with air start diesels they used to run them ahead or astern... they were a direct drive to the propellors... just some nostalgia for you!

Davoe, I recall seeing a safety bulletin from the WA Dept of Mines regarding 2h motors starting in reverse. The engines had been fitted with engine stop cables in place of the EDIC motor. So yes it is possible.

Yes the motor will run in reverse but only for a few seconds because the injector fead pump will be sending the fuel back to the tank, this is good because you have no oil pressure because the oil pump is also sending the oil back to the sump. Please don't try it its not good for the motor. Eric.

Most modern electronic diesels have built in to their computer system a function so that the engine will not run in reverse especially direct injection types eg: (landrover Td5's)
I remember as a
young fellow my uncle who had a Hercules diesel that regularly ran backwards as Wilsey said it had 5 reverses and 2 foward
