| Description of the problem | 2005 jeep wrangler. Well maintained. Highest quality oil, spark plugs, air filters, cooling system. Camshaft failure at roughly 50,000 miles. Excessive wear causing knocking. Diagnosis from chrysler: new engine required. No overheating, no abuse. The oil pump drive assembly gears are worn down so oil is not flowing properly. This is a possible cause for the camshaft failure. The other possible cause for the camshaft failure is that it is a flat tappet camshaft from the factory. This specific type of camshaft needs the zddp oil additive. Modern oil does not contain zddp because it causes catalytic converter failure. Without zddp excessive wear occurs. This is covered in sae bulletin # 770087. Sae is the society of automotive engineers. Once wear reaches a certain level further wear is rapid and causes catastrophic engine failure. Furthermore, my jeep is still under powertrain warranty. However, my warranty has been unlawfully denied because i have some unrelated aftermarket parts on my jeep. Litigation is pending on this issue. Chrysler has gone against their own written warranty, and well as federal law (magnuson-moss warranty act). |
