My Tundra with 75,000 miles has a camshaft tower leak and this oil is falling into the exhaust manifold without being noticed because it doesn't make it to the floor, but it gets to the sensors and starts ruining them. Toyota motor CO knows about this issue in all their 5. 7l engines and that its a factory robot error by not applying enough sealant in the gasket. And this is just being fixed if you are either under factory warranty or extended warranty. The vehicles loose power and if driving on a highway can cause a major accident. The least this company can do is offer a voluntary recall but they are refusing to do so because the fix will cost them $3500-$4000 from all their 5. 7l engines assembled in the u. S. So for my safety and the safety of many Toyota drivers and general highway drivers safety, I hope this would be taken into consideration. Thank you.
I have noticed an oil leak from the camshaft housing on my passenger side. This has led to oil burning on my exhaust manifold which is a fire hazard.
My 4x4 Toyota Tundra crewmax with the 5. 7l engine was diagnosed with a cam tower leak with only 15,000 miles on it. Fortunately the vehicle was still under the factory power train warranty. Toyota made the repair and provided a rental car for me. I have heard this is a common problem with the 2012-2013 5. 7l engine and I want this issue to be more public. I worry owners of this vehicle will be stuck with the $2,300-$3,000 bill to fix their own vehicle if their vehicle's power train warranty has expired. I also worry the engines could leak oil onto the exhaust manifold and catch fire.
