My 4.3 is still ticking on passenger side towards cab. I think its #4 or 6 lifter. I have changed oil with Plus50II 15W40 with 1qt of MMO and half a can of seafoam. I have driven it about 200 miles. How long until i hear a difference, if I'm going to?

You probably wont.
 
Thats what i think it is. I sounds just like it. Its not a leaking exhaust manifold, just changed plugs and still does it. It increases with rpm. However i cant hear it inside the truck. Just when i am by the front right wheel well.

I want to see if MY truck still ticks after I find out if I have oil pressure or not.

Some have had good results with Kreen. I'd try that. On the other hand, I would not adjust the lifter(s) to get rid of a tick. What happens if there is some trash in the lifter that breaks loose after you have adjusted it? High potential for a burned valve.
 
My 200K+ '94 Sub ticked for the 1st 3 years I had it, until I gave it to my brother & he flogged it mercilessly (skipping oil changes, running it low on oil, etc.)-lifter tick magically gone!

Agreed...

First time in over 50 years I've heard some someone recommend against what used to be considered routine service...

why would trash break loose? That makes no sense. Also valves burn from being too tight and spending too much time being open.
 
How are you driving the vehicle. Maybe an Italian tune up for a a short while on a freeway or something daily for a week might help.
And its only been 200 miles. If the lifter has gunge in it causing the tick its gonna take a while to dissolve. Run the oil change interval out then make a judgement call
