Car Forum / Nissan / Nissan Maxima / August 2004Camshaft Failure
My camshaft failed one month after the dealer changed the timing belt. The dealer is saying that the cause is from a build up of wax from using Quaker State oil. Has anyone been down this road before? I sure would appreciate any advise. Hopefully I have a case but can handle it if it was not their fault.

The camshaft was not removed from the car but the failure is inside or just beside the first bearing closest to the timing belt/pulley. >> > My camshaft failed one month after the dealer changed the timing belt. >> > The dealer is saying that the cause is from a build up of wax from [quoted text clipped - 6 lines] > The camshaft was not removed from the car but the failure is inside or > just beside the first bearing closest to the timing belt/pulley. It's not their fault. The engine oil passage feeding oil to the cam bearings plugged up and the cam seized in the engine.

One thing people don't consider are the hours an engine runs. In stop and go - traffic jam type use, 3000 miles is WAY too long to go between oil changes.

Some of the european cars use a variety of ECM data to indicate when to turn on the "change oil" indicator. That's probably more reliable than a static # of miles. > > >> It's not their fault.

The car had the oil changed every 5,000 miles or less when I used both Mobile 1 Synthetic or later regular Quaker State oil. If my memory is right, the manual says to change every 7 or 8000 miles. Is lack of oil the only reason the camshaft would fail? Normally lack of oil would cause the bearings to fail and stress would cause a shaft to fail. This is in the aerospace world - perhaps different in the auto world. Camshaft failures on the Maxima engine are rare so if it was oil related I would expect to hear about more of them. I'm favoring a rebuilt factor engine rather than repair the existing one. >oil the only reason the camshaft would fail?
