Clicking noise at high RPM?
Never done it before in my truck...did it once on accident today then again to see if I really did hear it. '94 4.0L OHV V6. Above 4300 RPM or so (guesstimate) I get this clicking noise...not LOUD but noticeable. Valves/pushrods? Any problems? Things to fix? It doesn't do it at lower RPMs, so I'm just keeping it below 4K now. Advice? Thanks.

Yes...note made lol. I'll keep her down below 4K from now on, especially considering it's a pushrod engine. 4K is still enough power to give the truck a run for it's money! Thanks handyman43358!

If I get my 2.3 up to 4 grand with the miles it has on it..... I'll be lucky not to burn a quart or two of oil up. I run er up to about 2800 most of the time. Every now and again I will get er up to 4, but trust me, thats ALL it has. It absolutely will not carry anymore RPM's than about 4000 MAX.

Could be a lot of things; its hard to say without actually hearing it. For piece of mind, you might consider verifying correct oil pressure by hooking up a mechanical gauge and comparing it against the spec.
*As you probably know, you don't have to worry about over reving it. There is a rev limiter in there.

Engine Noise At High RPM
I noticed the same problem with my 97 Ranger, but it's only a 4cyl. I first heard the noise last week when I started to go up a hill in 5th gear (but rpm's were fine). After downshifting the noise went away but is starting to show up on flat surfaces now in 5th gear when I go above 60 mph. I haven't noticed the noise in any gear other than 5th, any suggestions? This truck only has 97,000 miles on it.
Thanks,
James

You might want to start your own thread, jcatkinson- 60 mph in fifth gear isn't revving all that high, so I'm fairly certain you're looking at a different problem.
My first instinct is to check the level of the fluid in the trans, since the problem only occurs in fifth. These tranny's have a nasty habit of springing leaks that only leak when you're driving, so you don't see any spots on the ground.

Thanks for the reply. Tranny fluid is good, just had it changed the day before. I just drove the truck from WA state to central CA and initially noticed the noise going up some big mountain passes. The noise will stop instantly when I take my foot off the gas. This truck has all the CA emissions crap on it and I'm wondering if it might be an exhaust/catalytic converter prob?

he can have this thread I'm done with it lol.
jcatkinson, I would almost say it sounds like you're bogging the engine, but at 60 in 5th, no way. Does the noise change with speed? Does it sounds like it's coming from the engine or tranny?

Clicking Noise
I can't really tell where the noise is coming from, but it seems to be coming from the middle of the eng. compartment. The noise does get louder if I lay on the gas but instantly stops when I take my foot off. I did notice it a couple of times on flat ground when I was trying to accelerate but it happens almost everytime when I'm trying to go uphill. I forgot to mention that I just put 2 sizes larger than stock tires and wheels on her, but not sure if that would be causing the problem.
Thanks,
James

So I think I might have figured out the "ticking" noise in mine.
I ran some seafoam through the intake, and it made that noise at about 2000 RPM. I then realized it was just "pinging." Once the seafoam ran through it, there is no noise up through 4000 RPM. Which doesn't bother me getting it up to 4 grand, because once I get above 3000, I'm almost certain she burns a half quart
. High miles will do that to an engine:d.

Which is why I still love mine. I rev it when I feel like it, and it doesn't use a drop between oil changes. Makes me happy!
Did it start doing it after you changed tire sizes jc? I don't see how that could do it, but better to explore all options.

Do you have a tach? If not, does the truck "feel" like it's bogging?
I have basically the same truck (although with twice the miles), and my friend has a 2000 4-cylinder with the same gears, but bigger tires (15" rims, not sure of the tire diameter). Mine likes fifth anywhere over 50-55, while his won't take fifth before 55 without lugging, and likes to run up to 60 in fourth before shifting. I can't imagine running 16" rims on mine without regearing.
