It happens all the time with 1998-2002 corollas. Pistons run too hot and oil turns to carbon in rings and piston oil holes even with good maintenance. I got oil consumption after 70000 miles of 4000-5000 mile OCI intervals.

Some other toyota engines had the same problem to some degree. Recently discontinued 2.4L had that problem too.


I have one of the 2.4L engines that have the oil control ring issue. It has 80,000 miles and consumes about 1/3-1/2 of a quart in a 5000 mile OCI. BUT, it has been run on PP 5w20 since new. So it is very clean inside. It has been flogged by 3 teenagers since new as well. So it is a very sturdy engine.

BTW, oil doesn't "shoot all over the place"

so maybe he just had his oil changed and didnt tighten the drain plug? you could speculate until the cows come home until facts come out.

Contractor? So he probably ran it out of oil. My guys are brutal on work vehicles.

Probably so, but they might be used to running out of oil and it being fine afterwards.

I have seen a 500K mile 1990s F-150 that got oil when it ran out or made noise. Somehow it still ran strong when full on oil, but it knocked fierce when first started after getting an oil change for the first time in 2 years. Knocking went away after a few seconds. This was one of those trucks where the key is a pair of needle nose pliers.

I had a friend once with a 318 in a 3/4 ton. We went someplace and the motor started knocking. So he stopped and dumped in 5 quarts of oil. I was shocked, but he assured me that he'd been doing that for the last 20k. I don't remember how many miles on that thing but it was well past 100k.

Total bogus dealer story and this guy fell for it!! Time to school him with your knowledge from being a BITOG member!!

a 70k mile toyota engine is not going to "carbon up" and throw oil everywhere. Just ain't gonna happen and especially not due to ethanol in the fuel! Ethanol is actually cleaner burning than any gasoline with virtually no carbon by-products once burned.

Tell your buddy he got suckered not once, but twice!

This is why hearsay isn't admissible in court. It's meaningless.

If he took the "100k zero maintenance" garbage seriously it would no doubt coke the rings.

That's SOP for my guys with the 6L GM vans and trucks.

Their idea of an oil change is resetting the OLM so it stops bothering them.

I am pretty sure this also happens on GM engines with AFM because of Too much oil consumption. This leads to needing new pistons and rings. There is a TSB on the issue. I have the TSB.

It may not be the exact same scenario.. but the fix sounds to be the same.

Sorry it took me a while but I got with my contractor friend for a few questions. He said it was oil coming out of the tailpipe not in the engine compartment.

He said he took it into the Toyota dealer for all his oil changes and maintenance every 5,000 miles.

The new 2014 is his forth Tundra as he drives all the time.

He said the problem happens to the 2012 models like his and the 2013 models.

I told him I looked on the Toyota Nation/Tundra forum and there was nothing about it. He said it had not come out yet and they were trying to keep it quiet.

We used Toyota Tundras at work for a while and they didn't get good gas mileage. They all got turned in at the end of the lease.

I do not like to say this. But something is not right with your friends Toyota dealership. If your friend did not have any resolution with the dealership service manager he should of contacted Toyota's regional manager with the details. Something would of been done without having to buy a brand new truck unless this is what your friend was wanting to do.
