When I found out what happened and called them, they said they just put 5 quarts of oil in it and it was "purring like a kitten". They tried to claim no damage was done.
Numerous debates then took place, but when we drained the oil after 500 miles of driving and they saw metal shavings in the oil, they agreed there was damage and got their insurance company involved. They found the crank shaft bearing froze and turned in the block. They put in a rebuilt short block from Toyota, and sent the heads to a machine shop who found no damage. After about a month with an insurance company SUV, we got the 4Runner back.
We had our local reliable mechanic change the oil in the new engine at 500 miles. A few days later it was making a noisy lifter sound when starting cold. We took it to the Toyota dealer and the best they could come up with was that we put an "after market" oil filter on it. They claim the Toyota oil filter might have a valve in it that keeps the oil from draining out so it has oil in the top of the engine when starting. Has anybody out there heard this before or know if it's true?
Then we took it out 4 wheeling with the Jeep. I was being gentle with the 4Runner and it's new motor. Shortly into the trip, the Check Engine Light and both VSC lights came on. The Toyota dealer then replaced an exhaust manifold and catalitic converter (one piece right?), belt, tension pully, cleaned the fuel injectors, and checked valve adjustments which they said met specs.
Oh don't let me forget, they gave us back our money for the oil change when we asked for it.
I talked to an attorney early in the process, who said he would have to get an expert involved before he could do anything, and recommended we document everything, which we have. I also talked to an old college roommate attorney who basically said it would be a tough fight. Our auto insurance agent said it was a tort claim and not their problem to deal with, but wished us luck after asking if we used synthetic oil or Slick 50.
Now we're torn between trading in or selling and being upside down on a 60 month loan, or hoping for the best and looking at it from an optomistic point of view that we have a newly rebuilt engine in a car with 70,000 miles on it. I sincerely bought this vehicle with thoughts that it would go 250,000 miles without major repairs. Now I'm trying to decide if I should spend any money on new tires to replace the Michelin tires that it came with. I want to go play in the mud but the Michelins have 73,000 miles on them and not enough tread to begin with for what I like to drive through. But that'll have to wait for another post...
