Isuzu Rodeo TICKING NOISE !

[rodeo02]

Adding one qt of ATF in to a 5.5qt sump wont hurt a thing. The ONLY thing a modern ATF will do is lower the viscosity of the oil in your sump & make it flow easier. Modern ATF's are nothing more than a 20wt oil with a very weak additive package & red dye. Do an analysis on new ATF and it will confirm this 100%. Years ago (25+) ATF was actually made with whale oil. This is what made it highly detergent back than. Today there's no real "detergency" to ATF at all. A sealed tranny with no moisture, fuel, combusion byproducts does not require a detergent.

No, oil level dosen't affect the noise my truck makes, It maybe a T-belt tensioner, it does have 117,000 miles on it. any ideas would help.
thanks!

My 94 does the same thing, it must be a Isuzu engineers modification to the oil sending unit to start the ticking when :
1. oil is low
2. oil needs to be changed.

Deep creeped the heck out of the thing twice and I hear it once in a while still.
Maybe it was those 11k oil changes.Haaaaa haaaa!
I have sinned and repent.

my 93 rodeo makes a annoying ticking sound also! and i am desperatley looking for a solution other then spending 0ver 400 dollars to have the lifters replaced! sea foam? might try that i think!

Try a quart of Rislone engine oil additive. I had that noise in a 1997 and tried everything imaginable-different weights of oil, synthetics, blends, etc., and one quart of Rislone got rid of the noise.

ok i'll do that! thanx

Don't bother replacing the lifters, those that have, have experienced it all over again with a matter of miles.

It's the nature of the beast...more harmful to you then it is to the engine.

got a 94 passport with 180k and had ticking since 80. don't mix ticking from need of an oil change and the clacking of the timing belt hyd. tensioner. if it's tolerable, it's time for an oil change or additives. if it drives ya nuts and your embarassed of it, it's the tensioner. got me a kit from that ebay link...parts on the way(hope it lasts for a bit) kit with water pump and pulleys because i don't want to tear it apart again.

Are you in Sarasota?

Never mind. I see you are from south Sarasota County. Waves coming this weekend! I used to surf your jetty quite a bit...

well i don't know about that. hydraulic lifters may need replacing. maybe not. if someone replaced them and that wasn't the problem, of course they still had the problem. and if they didn't check anything else while in there, well...duh.

i've been reading a number who are now discovering that when they tear the top cam assembly apart that some of the cam 'bearing' surfaces are excessively worn which has resulted in extra play and decreasing oil pressure in that circuit, which in a never-ending cycle continues to exacerbate the problem. replacing the necessary parts has resulted in a fix. there is also some evidence that the oil pressure valves in the head may become clogged so that the oil pressure to the cam area is insufficient, and actually removing those valves may have a positive effect in providing consistently good oil pressure to those parts.

on the lifters etc, here's an excellent post in the HallofFame at planetisuzoo

back to this poster's particular case, it may be the nature of the beast, but that is not all that clear to me from here (hear).

also, while many of us 'live' with the ticking as a cost-decision, it is not accurate to say that is not affecting engine performance or engine longevity. any time a valve isn't opening and closing when and how much will always affect the combustion process. the computer is so good at masking such things that driveabilitiy factors aren't even realized by the driver.

I agree that if the ticking is EXCESSIVE, then yes it could be not so good for the engine.

However, Isuzu engines are NOT the only ones that tick/tap, whatever you want to call it. By far, they are definitely not the only tappers on the road.

Take my newly acquired Toyota Tacoma 3.4L V6 for instance, it ticks/taps louder then my Isuzu with only a third of the miles. While we didn't care for this, we went and test drove many other Toyota's with the same engine, they tick too.

Even my old Toyota with the 22re 4-cylinder engine tapped - LOUDLY mind you.

My sister had a Trailblazer 4.2L GM engine, guess what, it ticked/tapped; we owned a '99 Chevy 3/4 ton with the 6.0L Vortec engine, you got it, it lightly tapped - not too bad.

Day after day I make it a habit to listen to other engines just to see how loud they are, Toyota's and Nissan's are right in line with the tapping deafness of the engines; Chevy's are right in there too, not all of them are experiencing piston slap either. And, by far the loudest I'm hearing on the roads are Ford Explorers, Mitsubishi's, and Chevy Colorado's.

I completely agree with what you're saying, however, I've known many Isuzu owners whom have gone well over 200k on a tappy engine without issue. I do believe Isuzu engines in general tend to be louder then most, I've known that from the first Rodeo I ever bought, although it had the 3.1L GM engine, it was a louder sounding engine from off the lot brandnew. Probably more to do with Isuzu's air intake design.

I called her Airwolf, in fact, she had a custom paint job, jet black with purple pen-stripping down the sides - and she sounded exactly like Airwolf upon taking off from a light and/or giving it the juice while climbing the mountains.

Just out of curiousity, Trooper, does yours tick?? Have you ever torn yours down?

So, is this a manufactoring defect?? Can't rightly say that it's due to neglectful oil changes, many upon many people have always changed their oil every 3k miles and still experience a noisey engine.

yup....
nope...

the noise however is intermittently getting louder and i'm trying to get a handle on any consistency to the occurances.

i'm considering taking the cam area apart....but we'll see.

I wonder if it's just inevitable.....I mean, we've all used different oils and different viscosities with overall the same oci interval, and yet many upon thousands of Isuzu's still experience the same fate.
