G'day everyone.
Last weekend I was out doing some 4WD in VIC and came across an issue that I haven't seen mentioned here (at least I couldn't find it when I searched on this or most other forums that have the same engine). Basically I went up a very very steep climb (25-40 degree incline) and as I got to the steepest part a shitload of blue smoke came out of the exhaust so I assumed I cooked a seal or something had given. (Should be noted in 1st gear around 4500rpm)
Anyways got to the top and there was no more smoke and I haven't been able to repeat it (I didn't try driving back up any hills as steep either). I've since done around 400kms and driving the same as before and no smoke at all, this was the only incident.
So my question is, what could cause this? I'm leaning to believe that on very steep angles the surface of the oil in the sump sits high enough that some oil can be sucked in through intake valves. Anyone have any ideas or other places to check so I can inspect/replace anything if required
Cheers, Dan
