Smoking While on a Incline

Burning oil is typically blue smoke. White smoke is often associated with coolant leaking into the cylinders. If your pistons are “pumping too high and hitting the block”, you are 1 millisecond away from your engine seizing.

I think your buddies theories may be bunk. Hopefully someone else can give you a different opinion.

 

The coolant level has not dropped. All the fluid levels have not been affected, I find that to be the weird part about this.

I would really hope he is off then if I am that close to seizing the engine!

 

That's not going to happen anyways because the piston is restricted to mechanical travel of the connecting rod and crankshaft journal.

I have read that several times, I would like to find a answer though.

 

Fuel knock. Very similar thoery to my orignal one. Only i was thinking of fuel starvation. But this could be possible. But our trucks are direct injected and standard injected i believe. But im not sure in the standard injection works all the time. Let me look into it and get back with you.

 

While you have the plugs out check the PCV valve too.

 

valve cover breather towards the back of the engine on the driver's side. Oil pools in the heads near the rear due to incline and being unable to drain as fast, oil gets into the breather, gets sucks into the intake, burns in the cylinder. This would be my guess.

 

, the 2GR-FKS is a 3.5-liter (3,456 cc) 60º V6, with double overhead cams and four valves per cylinder, derived from the engine in the 2015 Lexus GS. Bore and stroke are 94 and 83mm. It produces 278 horsepower and 265 lb.ft. of torque—up 42 hp and, er . . . down one lb.ft. from the previous 4.0-liter 1GR-FE V6. Its most intriguing design feature is the fuel injection system, which combines port (fuel injected into the intake manifold just above the intake valve) and direct (fuel injected directly into the combustion chamber) operation. At low speeds, the system can combine both injectors or use one, as needed, to provide stable cold starts, prompt response, and low emissions. At high speeds and high loads, the system switches to direct injection: Each cylinder is equipped with an extremely high-pressure injector that sprays atomized fuel in a horizontal fan-shaped pattern into the combustion chamber after the piston has begun its compression stroke. This promotes a complete burn, reduces detonation, and cools the intake charge, enabling a very high 11.8:1 compression ratio while retaining the ability to run on regular gas—thank you Toyota! (Direct injection is promoted as the latest in high-tech engine wizardry; in fact the 1954 Mercedes-Benz 300SL had it, albeit with mechanical rather than electronic control.)

Okay so according to this it uses standard and direct at low speed low load. But the only issue with his thoery is that the fuel injection spray ay the valves. So the fuel in theroy should not roll around in th intake like a carb car could. The more i think about the more i think hes talking about carbs.

 

Eithet of these explain the smoke but not the knock.

 

Oil has a lower equivalent octane than fuel. If it's burning this heavily, it will cause predetonation.

 

Sorry, my sarcasm didn’t translate I guess. If your crankshaft bearings have failed, you pistons might lift higher than normal, but only once (that millisecond I mentioned).

 

we skrait, I prolly should have quoted the one you quoted instead of yours. lol

 

I flipped my TJ, and after I pulled the plugs to clean out the cylinders, on start up it billowed white smoke for about 10 minutes. Jeep has 3 cats I assumed they were catching the majority of impurities in the exhaust.

My guess is the back two cylinders are gets splashed with oil.

 

mine has done this before, but only when on an incline AND driver side down. gave an oil warning but i dont remember if it said pressure or level.

 

@CaliDevilDoc

 

PVC value and intake are completely clean.

 

thanks.....

 

Go look at your driver's side rear valve cover....there's a breather line that goes right into the intake manifold.
