Hello, I am writing to tell you about a new BREAKTHROUGH method for repairing a leaking Coolant Transfer Pipe in the BMW N62 V8 engine block using the BimmerFix Stint. The N62 V8 is a popular BMW engine that was used from 2002 thru 2010, in such fabulous vehicles as the BMW 735i, 740i, 745i, 750i & Li, 645Ci, 650i, 540i, 545i, 550i, and the X5 SUV. Located deep inside of this BMW N62 engine is a Coolant Transfer Pipe, which carries antifreeze from the Water Pump to cooling chambers within the engine. However, the Front Seal on this Cooling Tube can fail in as little as 40,000 miles, and start leaking antifreeze from the engine block, through a weep hole in the Timing Chain Cover. When this happens, the car will lose antifreeze from the engine, and the engine will overheat. In the past, this has been a very expensive repair because it required disassembly of the engine, in order to access the leaking Cooling Pipe Seal. The original method of replacing the crossover Coolant Transfer Pipe required the removal of the Timing Chain Cover. This repair could cost $6,000 or more at the BMW Dealer. Then, an after-market Collapsible Coolant Pipe was developed to save time and money on this repair. This Collapsible Coolant Pipe method involves removing the Intake Manifold, cutting out the old Coolant Pipe and installing the after-market Collapsible Coolant Pipe. But even this method required many hours of shop labor and expensive parts and supplies. The repair bill for this method can still cost between $1,500.00 and $2,500.00 to remove the Intake Manifold, cut out the old Coolant Pipe and install the new Collapsible Coolant Pipe. However, BimmerFix Products Co. has discovered a BREAKTHROUGH system to stop the leak! The BimmerFix method is much faster and less expensive than these old methods. This simple, yet durable and long lasting method inserts the BimmerFix Stint into the leaking crossover cooling tube, through the Timing Chain Cover. The thin aluminum sleeve creates a long lasting repair that is much easier and less expensive to install than the old repair methods. The new BimmerFix Stint will stop the Coolant Pipe leak, and only requires the removal of the Water Pump. This new patent protected invention can save YOU or your customer's time, hassle, and thousands of dollars. It works or your money back! Save time and money! Take a look at www.BimmerFix.com.

Greetings, This is a very common issue with the N62 engine. It is most likely from leaking valve stem guide seals. The typical fix was to replace the valve stem guide seals by removing the cylinder head. I've seen dealers quote in the neighborhood of $10k+ to do this job. We have a way where we can do it without removing the cylinder head, thus reducing the cost of repair significantly. We would need to inspect the vehicle first to determine if the symptoms are from the valve stem seals or the oil separator. Give us a call and set up an appointment.
