2004 BMW 7 Series Engine

ENGINE VALVE GUIDE SEALS MADE OF IMPROPER MATERIAL THAT FAILS CAUSING OIL LEAKAGE INTO EXHAUST, FOULING OF CATALYTIC CONVERTER, FAILURE TO PASS INSPECTION AND POLLUTION. THE VALVE GUIDE SEALS ARE NOT COMPATIBLE WITH HIGH ENGINE TEMPERATURES WHICH CAUSES THE SEALS TO FAIL AT 80,000 TO 120,000 MILES. MY SEALS FAILED AT APPROXIMATELY 95,000 MILES CAUSING OIL CONSUMPTION IN EXCESS OF 1 QUART PER THOUSAND MILES. REPLACEMENT OF THE VALVE SEALS REQUIRES EXTENSIVE ENGINE READ DOWN AND COSTS APPROXIMATELY $9,000 TO REPAIR.

COOLANT TRANSFER PIPE SEAL IS MADE OF IMPROPER MATERIAL THAT IS NOT COMPATBLE WITH HIGH ENGINE TEMPERATURES. SEAL FAILS CAUSING LOSS OF ENGINE COOLANT. SEAL FAILS AT 40,000 TO 110,000 MILES. REPAIR IS APPROXIMATELY $6,000 BECAUSE ENGINE MUST BE TAKEN APART TO REPLACE THE SEAL. MY SEAL FAILED AT 104,000 MILES. LOSS OF POWER STEERING AND VEHICLE STABILITY CONTROL DUE TO COOLANT LEAK ONTO SERPENTINE BELT.

I HAVE A 2004 BMW 745I, I NOTICED A LOT OF SMOKE COMING FROM TAIL PIPE WHEN THE CAR IS IDLING/DRIVING. I TOOK IT IN FOR A DIAGNOSTIC AT A REPLICABLE REPAIR SHOP, AND I WAS TOLD THE VALVE GUIDE SEAL'S WHERE WORN AND NEEDED REPLACEMENT. THE PROBLEM IS THAT THE VALVE GUIDE SEALS BECOMES HARD OVER TIME AND DOESN'T PROVIDE A PROPER SEAL FOR THE VALVE STEM'S. THIS ALLOWS OIL TO PASS THROUGH THE VALVE STEM SEALS AND ENTER THE COMBUSTION CHAMBER AND THE EXHAUST.( NOT ONLY DOES THIS CAUSE POLLUTION) IT DAMAGES THE CAT CONVERTER THEREFORE YOU CAN NOT PASS A SMOG TEST. THIS IS A WELL KNOWN ISSUE BY BMW, BMW REPAIR SHOPS, AND CERTIFIED MECHANIC ACROSS THE UNITED STATES. I CONTACTED BMW CORPORATE OFFICE REGARDING THE PROBLEM, I WAS THEN CONTACTED BACK BY [XXX] WITH BMW EXECUTIVE CUSTOMER CARE. I WAS TOLD I NEEDED TO TAKE MY CAR TO BMW OF ONTARIO TO GET A DIAGNOSTIC, BECAUSE THEY DON'T EXCEPT THIRD PARTY OPINIONS. BMW OF ONTARIO CONTACT ME TO TELL ME IT WILL BE $6,500.00 BECAUSE THEY NEED TO REMOVE THE ENGINE AND TEAR IT DOWN FOR INSPECTION. I WAS LATER CONTACT BY [XXX], WHO TOLD ME THAT HER FIELD MANAGER DENIED ANY FURTHER DIAGNOSTIC OR REPAIRS ON MY CAR. SOMETHING NEEDS TO BE DONE ABOUT THIS VERY INEVITABLE ISSUE THAT HAPPENS TO 5,6,7 AND X SERIES BMW MODELS THAT ARE ON THE ROAD CAUSING NASTY POLLUTION.
