Seafoam, duh!

What weight oil are you running? I had lifter noise on warm startup with 5w30, went to a 10w40 and it's quiet as a mouse.

Seafoam goes in the crankcase for lifter noise - run for a few minutes and change the oil. Don't drive around with ALL of it in your crankcase, you may get by with half...

When you put it in the crank - it works to clear away any varnish and gunk that may be causing the lifters to stick in their bores, or dissolve crud that's preventing them from filling up with oil.

When you suck it in your intake................. it cleans the combustion chamber, backs of valves, etc. Not lifters. Think about it :jester:

Should I put some in the crankcase and run it for a few minutes then change the oil, or change the oil then put some in and leave it, or change it, put some in, run it, and change again?

Yes, that is an option, but i'm looking to see if i can stop this annoying valvetrain tap. Hopefully I dont need to replace anything, but i want to see if i can clean it up before going any further. I would buy some of that auto-rx stuff, but i want to change my oil asap.

Take 1/2 to 3/4 of a Quart of tranny fluid and add it to the oil,If ya are sticking from sludge or varnish the trans fluid will dissolve it .... Ya can even run it around a bit just don't beat on it or work it hard, then drain the oil, change filter and refill with a good oil..

Yes, that's the crap I'd add ONLY.

Unless you have 8k on dino oil, don't worry.

This old GM tech told me about that once. He said about 16 oz. of it in the crankcase helps out a lot. My cousin does it in his expedition, with no issues. I never tried it, though.
