Engine Oil Leaking problems of the 2010 Toyota Tundra

Engine leaking oil while running at the cam towers on both sides causes oil to drip onto engine exhaust header. This unsafe condition could cause a fire. This condition happens to all 4. 6 and 5. 7 Tundra and sequoia engines produced after 2007. This is an extremely expensive to repair. The manufacture made these engines with inferior sealant at the cam towers.

My Tundra has 48048 miles on it. I took my Tundra in for an oil change and was told there was a oil leak in the cam tower. The cost to fix it was $2850. It was no longer under warranty. I did a little searching and found that this is a problem that has occurred frequently in this engine. I contacted Toyota and was told, after they consulted with the dealer, that the problem wasn't a defect, but caused by engine wear and altitude. They offered to pay for parts, which were $420. If it is really engine wear, I expect this to happen again. In talking to the dealer, I was told this is a one time fix, and it should not happen again. Something isn't right here. Either it is a defect in the engine and this repair will fix it. Or it is normal wear and this will keep happening. I feel this is a problem that Toyota should fix, since it seems to be happening frequently. Many people reported it happening while it was under warranty. Mine just happened to have occurred after the warranty expired. Either way, it is not acceptable to have this happening in this engine with low mileage. Apparently the oil leaks down from the engine onto the exhaust part of the vehicle and can cause fires. It also can leak out and cause engine damage if the oil gets too low. I hope you can help me.

I bought my 2010 Toyota Tundra brand new in Feb. 2010, during a routine oil change at Toyota dealer recently, engine oil leaking was noticed by the technician. The repair was done to reseal both cam box housings and replaced seals and gaskets that are related. It costed over $1800. Unfortunately, the vehicle just passed the powertrain warranty, since it has been 5 year and 11 months, but the mileage is at 38,000, related low. I have contaced Toyota us headquarter, told them the oil leaking most likely started before 5 years mark, but it was just discovered now. They refused to reimburse the repair cost. The dealer service technician told me that he has seen many Tundra had this oil leak issue, and most of them were within warranty, so there is no recall for this issue so far, I also did research on internet, found other people had this oil leak issue for their 2010 Tundra and 2011 Tundra. I would like NHTSA to investigate this wide spread issue and hopefully let Toyota do a recall for this defect!.
