Smoking While on a Incline

I experienced that... twice

And the joy of replacing a VP44.

 

I never smelt anything.

lol well shit, smoke just started happening, and I couldn't tell. not until it toned down and was obvious from the tail pipe.

 

For what it's worth, previous internal discussion on the situation led me to wonder if it was a malfunction in the valve timing (a theory which stemmed from the clicking), causing uncombusted deposits to burn from the previous cycle. Why this would occur only at incline is what makes me question the plausibility of such an issue.

 

I have nothing useful to offer this thread... but I will say, the white smoke makes for a cool photo.

 

Diesel yes gas motor no

 

This happened to @BigMike

I'm not sure if he ever figured out the cause.

 

agree lousy design and the reason I know it is I owned an early Toyota 4 x 4 with this exact design flaw as I posted earlier in this thread. Toyota made the return oil passages in the head too small so the oil would gather in the top of the motor causing oil not returning to the pan fast enough. So I agree it is a bad design but that does not mean a bad design could not make it into production. This 3.5 is more of a car motor so it does not surprise me that they would find annoying issues in first years of production in 4x4 application.

 

Condensation or accumulated water rolling into the intake?

 

No on their side. Smells like burning oil though

 

Do you suggest a oil change and make sure the level is right? It is dead center of the 2 notches on the dip stick right now.[/QUOTE]

As long as the oil level is correct a change is not necessary. I wouldn't bother taking it to Toyota because they're not going to be able to duplicate the problem unless they put front end up on a lift and duplicate the exact same incline and so on and then the dealer is most likely to tell you it's too high of an incline and it's not designed for that even though we all know that's not true and the truck should easily handle what you did without any issue. I believe this is 3.5 growing pains and a design flaw that will be corrected by Toyota at some point. On the flipside Toyota needs to know about to correct it so if you want to be the guinea pig go ahead but you could be setting yourself up for problems as well.

I am mainly concerned about it causing problems. It's going to be really annoying if I only have a couple of attempts at a hill climb before having to back out and let it reset before another attempt.

 

You know who knows about 3rd Gens? Unfortunately, he is on an unplanned vacation.

 

If this is an AT, I'd say the white smoke could be burning ATF. I had an old Toyota pickup that sucked in ATF intermittently through the block every once in a while and it would lose power and leave a white smoke screen behind me. The last time was when I saw a red light glowing behind me through the smoke!

Edits: Pull the plugs and see if any one of them is gummed up with burnt oil. It could be that you may have a head gasket issue, or ATF is getting into the engine elsewhere, and the oil is getting into a cylinder.

This is definitely a warranty issue for sure!! Don't drive further until you can verify the condition of your motor oil!

 

I will give that a try! That is my main concern, if it's a head gasket issue I need that taken care of before warranty is out!

 

I endorse this answer, it sounds like a better explanation than mine! But still rule out the possibility that one of the cylinders is burning oil by inspecting the plugs.

 

I have very little knowledge of engines, I know he said it's a issue on a cummins. Could it also be the issue on a gas? I do seem to lose power after it's been smoking for a couple mins.

 

what is that clicking sound just before the smoke?

and btw, i've been to choc before, that's not a leisurely stroll for a nearly stock 3rd gen. An "A" for effort fo sho!

 

THIS^^

 

Something is being starved of oil.

 

@Jake4848 didn't you have a problem in ardbeg doing a hill climb with it stalling because of oil pressure?


for OP any consideration for something damaged when you dropped off something?
Prior to the smoke something about wheels off the ground then it appears you dropped pretty hard on something.
