Next I spun around and climbed a steep ledge to the east side of V Rock. This ledge is fun because as you move right it slowly becomes more steep. There is a point at which my 1981 shortbed Hilux will not Crawl it, even with a 511:1 reduction, but yet a long wheelbase Hilux with a Marlin Crawler will go right up. So I was eager to take this 20% longer Tacoma up a much steeper section than I've ever tried and that is when this happened...

Everything was going good until the Tacoma began smoking!

So I backed down and waited for it to clear out.....which took quite a while!

It is strange that the smoke is white. This indicates water being combusted, such as a blown head gasket. It is typical to burn oil at severe angles due to oil shifting to the back of the pan and in a way flooding the rear cylinder(s) such that the piston rings cannot prevent oil from passing into the combustion chamber.....but burning oil through an engine results in a bluish smoke. For argument sake, there is a third distinguishable smoke color and that is gray which indicates a very rich fuel mixture.

Everything on my gauges looked fine so I reattempted the climb and up she went. Maybe the new emissions systems are just so efficient at even cleaning out blue smoke from burning oil.
