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

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

Hi Robert. Definitely worth a try!

Hello, I’ve got 1000km on my oil right now, so I’m just asking if I have to drain my oil after 450km, or if it is ok to continue my oil period up to 5000km with the Sea Foam inside?
Thanks

Hey Mathieu, – it’s ok to leave the Sea Foam in there for the rest of the oil period (till 5000km).

So black dirt in the crankcase will not affect engine lubrication for 5000 km !?

Hey Mathieu – thanks for the follow up. I should have clarified and added a few details in my response! If your oil is dirty enough to cause concern, go ahead and change it. With any gasoline vehicle (that has Sea Foam in the oil or not), I’d recommend checking the oil color and oil level every 1,000 km or so, and changing the oil if it becomes very dark/irregularly dirty.

In general, we recommend adding Sea Foam to the oil about 150-500km before you change your oil. That way, there’s enough time for the Sea Foam to circulate and you can drain away any reliquefied residues and deposits with the old oil when you change it.

If you have already added the Sea Foam to the crankcase, the Sea Foam itself will not harm anything if it remains in the oil for the full life of the oil. Of course, if the oil gets dirty before the oil period is up, you’ll want to change it. In newer vehicles, lots of people add Sea Foam early on in the oil period to prevent residues and deposits from forming. In older vehicles, it’s best to add the Sea Foam shortly before you change the oil so the residues and deposits that are reliquified by the Sea Foam can be drained away with the old oil.

Hope that makes sense and sorry I wasn’t more specific originally!
