I have never seen more than one hydraulic lifter go bad in any vehicle and by the way you described the sound it seems multiple things were clacking.

I have never seen a lifter go bad in a 4.0 ranger.

Did you find any inordinate wear on anything when you disassembled it the second time? You said you drove it 10 miles like that something will show wear.

Doing an online search it seems maybe I am making something out of probably nothing. Ok technically it would be best not to have any rust on the lifters but Ive read alot of posts where guys dont even think twice about running them.

Id rather replace them but that means waiting more days and spending 2wice what I spent for these.

Im gonna sleep on it I guess

I would not risk it
New in box lifters have a coating on them and no rust
Those have been sitting on a shelf somehwere for who knows?
I would use melling

I will say I have seen a collapsed lifter on OHV 4.0L engines maybe twice in my wrenching history. Most of them get weak and tick at cold start but eventually pump up and the ticking stops. This is usually over 250-350K miles
I wish I was there to hear the noise with the engine running.....
I had a 4.0L conversion I did into a 96 Ranger (4 banger auto to 4.0 and 5 speed) tic tick tick.... did new lifters, pushrods, rocker arms and all gaskets....tick tick tick still here it ended up being the NEW oil pump pickup tube connection and low oil pressure on cold start for that engine. But that ticking went away did not get worse.

If it was an injector noise you would notice a miss at idle
If it was exhaust it would show soot and usually gets lessend when things warm up and metals expand
If its a pushrod bouncing around in there then you need to find the abnormal wear spots on the pushrods and rocker arm cups to identify the bad cylinder

You should take a really close look at all of the parts you remove
This is a PITA and I feel for you
I have been through this on V6 and V8 engines, nothing sucks worse and drains your wallet like having to keep pulling heads........

I hadn't noticed this before, not sure how I missed it. All the Xs are where there IS a slight galling of the pushrods way down low.

Strange how each cylinder opposite is showing this?

Ok so pushrods possibly hanging up would most probably cause the
Valvetrain to clatter.

Now that I know what I'm looking for I can see where it was rubbing on cylinder head.

As it got hotter things expanded and it got louder.

I've read one other post online where someone else ran into this with a/m pushrods being too thick, they went with a factory rod and clatter went away.

I'm assuming I can get my burring tool, hog the out of the head and I'll be golden?

One thing that's always bothered me is the more I think about it the more I remember the noise being a very deep tone the more I think about it now I don't think it was a lifters or possibly the valve train issue more so maybe the pushrods striking the cylinder head causing that deep tone

It's like the commercial about the deer dancing on the hood. We've seen a few things ;)

Clearwater cylinder head.

I don't think it's the head but maybe a combination. I think I found a random post online from another 4.0 owner that experienced the same issue with A/M pushrods.

Can't finf that thread now though.

How could it not be the noise? They were either not allowing the valvetrain to operate correctly by hanging things up or they themselves were making the noise by striking the head.

It probably is UNLESS you had a bad lifter(s) also
The lifter(s) not pumping up can have the pushrods bouncing around in there, not centered on the cup

I ended up getting it together again yesterday afternoon and I'm glad to say that no noise upon startup.

Unfortunately when the engine heats up the ticking starts. I can literally stand there and start to hear it as it progresses.

I drove it home from work last night to Brandon approximately 50 miles and by the time I got home there is definitely a noticeable tick.
I'm thinking that maybe one of those cylinders I didn't hog out enough it's nothing like it was before.

Before it was holy Batman now it sounds like a typical V 8 that might have a lifter or two that maybe isn't quite pumping up enough.

Obviously I let the truck sit overnight when I went out there this morning to start it up there is absolutely zero noise, no noise whatsoever by the time I got back to Bradenton my shop it sounded the same as I had heard it yesterday just a little bit of ticking.

I can only assume that it's a pushrod tapping the head maybe one pushrod I'm going to drive it for 500 miles or so and I think the noise is going to go away.

I really do appreciate the responses on this forum.

Kind of sucks that I had to do it twice but on the same token I can really appreciate the experience.

I consider this to be a success I'm pretty anal about things and the average person that walks up to the truck probably would hear the ticking that I'm hearing but wouldn't think much of it.

I'm really surprised at the lack of power in the truck. I had assumed it would be a slug cause holy smokes that engine is narrow but it's no problem for me, I didn't plan to race it
