I searched and there were many threads and posts concerning how to go about doing the sea foam treatment. Normally I would read through all of them and try to figure out how to do this correctly myself but I'm short on time and the threads are confusing because there are many suggested ways to do it. I'm looking for advice from one of my fellow MSP owners who has done the sea foam treatment. Should I suck half the can through the break booster line and then put the other half into the gas? My engine just recently developed a tapping/knocking and I'm really, really hoping it is just a valve or lifter and that sea foam helps.
