Off Roading Angles

Hello everyone,

I did a little off roading the other day, which led me to ponder...

At what degree of angles will these trucks’ motors start running into oil starvation issues due to prolonged inclines or declines while iddling or crawling up or down hill?

Thanks guys...

Checked out the threads but it seems there are lots of speculation and no concrete answer to this...

 

Agreed. I will add “for an extended amount of time and under heavy load” to your assesment....

“Those problems” aka smoking out.... but the question still remains:

At what degree of incline/decline during a prolonged hill climb/decent will the engine actually sustain damage?

How long can the truck sit at idle, at say 35* incline / decline angle?

 

It still shouldn't smoke, 35 degrees or not

 

Should be able to calculate if we knew the fill level in the pan and how low the oil pick up is.

 

After comparing your picture to the thread posted above.... I'd say right about there... haha

 

I'd be interested if someone came up with a fix for this; maybe an extender for the oil pickup or something like that?

 

Dry sump!

 

Does anyone know where that's at? It kinda looks like the SE side of rainier, but the mountain looks off. Could be Adams. I was just there a few weeks ago.

In any case, I've been just as steep as the truck pictured if not more, for an extended hill climb and had no issues with it smoking. But YMMV.

 

I’m the guy who blew the engine in the other thread. It was after a hill climb (“truck hill” in Hollister). I wasn’t looking at the inclinometer but others quote truck hill as somewhere between a 34 and 45 degree hill climb. I had to rev the engine on the hill while the low oil light was on. We noticed the white smoke after the hill climb. Engine blew about 200 (highway) miles after the hill climb.

In my opinion this is a manufacturing defect...Don’t put “off-road” on the side of a truck that can’t climb hills.

 

Wow. That's brutal. Staying away from Truck Hill!
