VERY HEAVY OIL BURNING PROBLEM IF THIS IS YOUR PROBLEM PLEASE READ

Hi All,

This is indeed a severe oil burning situation. And yes checking out the PCV valve and associated plumbing is recommended. At the rate of oil consumption being a quart every 350 miles, the amount of Auto-Rx will have been deleted to next to non existent in the 1500 miles since installation. This motor is likely a candidate for the Fast Track application. However based on what the customer has done with changing out the oil and starting a second cleaning application, we need to stay the course. Many times if valve stem seals are particularly fowled, sometimes oil burning can get worse until the seals have been cleaned up in the full 360 degree circumference. As gentile and methodical the cleaning action of ARX areas of weak oil circulation take some time to clean up fully.

Do we have any indication of how much the oil consumption was before the initial application? Perhaps we are dealing with a motor that is sludged up to the point that oil pumped topside can not drain back to the sump. When this is the case oil will get drawn out of the valve cover at this same alarming rate.
If this is the case the consumer has no other option but to have a head replacement done. But is the oil pumped topside can drain back down to the pan through the casting holes from the head down through the block, then there is hope to avoid the dreaded tear down.

The customer needs to perform a basic test. The test is simple. After a night of the car sitting idle, take a measurement on the dip stick. Mark the high level with a scratch if necessary. Then fire up the motor and allow it to run for 5 minutes or so. Now take a second dip stick reading after shutting down the motor for 2 minutes. The level on the dipstick should be very close to identical if oil can freely flow back to the pan. If not then we have some serious blockage. Auto-Rxd dispersed in the motor oil can not clean where oil can not flow.
