Tundra Camshaft Tower Leak Meaning, Cause and Solution

‘Cam tower leak’ is a general issue in Toyota Tundras equipped with 5.7L V8 engines. You may face a leak in the camshaft tower between 50,000 and 100,000 miles.

Improper sealing, loose bolts, fuel pressure, cracks in the tower, or wear and tear over time are the common reasons for oil seeping from the cam tower.

Visible oil seepage, burning smell, smoke, etc., are the main symptoms of a cam tower leak in a Tundra. 21 known Tundra owners with camshaft tower oil leakage issues have filed a class action lawsuit against Toyota.

An unknown number of Tundras may have the same issue, and Toyota is prepared for it. They have already compensated for the repairs to the alleged Tundra engines and delivered 1600 Tundra vehicles to customers during the repair. The warranty for Toyota Tundra 5.7 engines is 5 years, or 60k miles.

In this article, I’ve covered what a cam tower leak is, which Toyota Tundra model years it affected, its causes and symptoms, how to fix a camshaft leak, and the recall and warranty for the vehicle.

What is a Cam Tower Leak Tundra

The camshaft is a part of the engine responsible for the cylinder valves opening and closing. The camshaft tower synchronizes valve opening and closing in all cylinders.

It is between the cylinder head, valve cover, and the tundra cam tower leak location. When the oil pressure becomes high, the seal is loose, or it wears over time, oil can seep from the cam tower.

Leaking a small amount of oil is not worrying, but more oil seeping may be a concern. So, looking out for symptoms and fixing the issue before it gets out of hand is necessary.

3. Oil pressure: Higher oil pressure in the engine may cause a small amount of oil to seep. It is not a noticeable issue for a low amount of oil leaking.

4. Crack: Crack on the camshaft also causes oil to leak out. Cracks may widen with higher pressure and wear over time. It causes higher oil seepage.
