Using Sea Foam to clean a GM 5.3L with a noisy lifter [SOLVED]

I have a GM 5.3L with a noisy lifter on cylinder one. The engine has selective fuel management system that transitions from 8 to 4 cylinders. Does it make any difference if I use Sea Foam in the oil for this type of system?

No worries Jim. Many people at our office have 5.3L GM trucks with active fuel management with zero issues (all use Sea Foam in oil). Adding Sea Foam the oil crankcase will work to clean the sticky residue that’s causing the lifter noise. Additionally, adding Sea Foam every oil interval will be a big help in your 5.3L!

I have a 2000 Suburban with a 5.3 engine. Aprox 10 seconds after I start the car a ticking sounds starts and continues for aprox 45 seconds then goes away. Can I mitigate this problem by adding Seafoam to my engine oil? Thanks
