How to fix a lifter noise in your car [SOLVED]

Is it safe to leave Sea Foam Spray in your upper motor overnight to soak in instead of 10-15 minutes? I have lifter noise that my last treatment of Sea Foam Motor Treatment helped with but only for about a week. I want the most potent treatment possible without harming my engine.

Thanks for the question Antonio. There are two things goin on here so I am going to provide two answers. Leaving overnight to soak: Yes, you can leave Sea Foam Spray in the upper engine overnight to soak. Just be prepared for the engine to run rough for a few minutes to allow it to recover. Lifter noise: You can’t clean lifters with Sea Foam Spray through the intake. Lifter noise can be resolved by using Sea Foam Motor Treatment in the oil crankcase. Sometime the lifter noise goes away quickly, but most of the time requires regular treatments (every oil interval). The big benefit to every interval is to progressively clean away all the old oil residue that builds up as engines add miles. Keep adding Sea Foam (or High Mileage) to your oil!

Do you add the seafoam before the oil change or after?

For overcoming lifter noise, we recommend adding Sea Foam 100-300 miles before your next oil change. That way the old oil residue cleaned by the Sea Foam can be drained away with the oil when you change it. Might take a few oil change cycles, but the Sea Foam will progressively clean things up.

I have a sticky lifter on my 2015 Sierra 1500. How long does it usually take to see noticeable changes from adding the seafoam?

Hey Chris – sometimes the noise goes away quickly, and sometimes it takes a few oil change cycles. Keep adding Sea Foam 100-300 miles before you change your oil (1 oz of Sea Foam per quart of oil) and it will get cleaner each time. Hope that helps!
