Is your 80 buzzy? (1 Viewer)

[RavenTai]

I don’t think the 1fz was built/tuned for high RPM, torque tops out at 3200PRM and drops off at higher RPM's, witch IMO is a very usable range for the 80. Stump pulling is right.


I thought it was Robbie who had some interesting comments about the stroke on the 1FZ I cannot find them now, kind of relates to this conversation.

Not enough choices in this poll..........

Mine ain't buzzy at all.......................

Although when the boost kicks in it does kinda whine..................

Been lurking for a while and tractor motors rule.

Shotts - you've left me no choice but to execute a net-citizens arrest on you and your mind-numbing post content. I'm pulling the plug and you are BANNED from IH8MUD.com

Get over it. Face it. The 100's motor buries the 80's and every 80 guy I wheeled with today (4) admits it. Buy a 100 and you'll change your tune buddy.

I didn't read all the replys but it could be one of the items that the belts run.
Remove the belts and run. If it goes away, then you need to replace on belt at a time.

My power steering pump on the 60 made a buzzing noise.
If I sprayed a lub on the shaft where it goes in the pump, the noise went away.
How to fix?? Easy, I sold it. I don't know what would fix it. I rebuilt the pump some time before the buzz.
I thinks its just a bushing (no bearing) Could be worn from too tight of belts.

Shotts- interesting (but not surprising) how you avoided addressing just about every point I made in my last post, kind of like you did in the earlier 80/100 thread. Let's compare notes when we hit 300K. I have a feeling my 1FZFE will still be ticking like a clock, and your V8 will *really* be silent, or on its 1st or 2nd rebuild.

I like that...

Guys, Guys!

Puleeeze!

Let's keep this a tech thread, OK? I'm learning a lot here...

 

[e9999]

well, OK, it's been a few days now without additional input.
So, I'll call it:

21 buzzies
22 not buzzies

since there are probably some buzzies out there that are assumed to be smooth by their proud owners , we can safely say that YES, it is very common for 80s to be buzzy, likely even the majority of them! So either it's a design feature or it's such a common problem that those of us who are on the buzzy side can now be at peace!

I rest my case!

Excellent conclusion. My 2004 Taco's the same way. Very nice motor overall. Smooth overall, revs well (though a bit powerless at higher RPM's), but as you accelerate you always feel certain buzzy vibrations at the same RPM's. All motors experience this.

With all due respect: If you say this AND you have experience with the 100's V8, then you're in denial. No comparison between those motors. In today's world, if the 100 had the 80's motor, NOBODY'd be buying them in the US. The 80's motor is gutless, it's noisy, rough, and isn't even in the same league as the V8 in the 100.

If however, you say this and you DON'T have experience with the 100's V8 then your opinion is noted, though you might to research and compare before your next purchase.

Shotts,

Didn't mean to offend any 100 owners out there and sorry if I did. You are correct in assuming that I have no experience with the 100 series Cruiser and I am sure that is a VERY capable rig. Whether it is superior to the 80 series is largely a matter of opinion. Personally, I prefer a solid front axle with a factory locker, and an Inline 6, but that is just for me, and I do not wish to influence anyone towards my personal taste.

I have had V8's before, but there were all domestic engines (made by the big 3). In my opinion, they were not great motors, largely because my experience with them wasn't great. My cruiser with 120,000 miles runs flawless, something I couldn't say for ANY V8 I have had personal experience with. And I don't think it's a US vs. Japanese engineering thing either. My uncle has a Ford with the 300 Inline 6 and he has 325,000 miles on his truck and it runs great (and the engine has never been rebuilt), which is saying a LOT for a Ford product made in the late 80's.

I am not a mechanical engineer by any stretch of the imagination, but I think that the inherent balancing issues mentioned by others in previous posts show scientifically that an inline 6 (in theory at least) has a slight design edge over a V8.

Not looking to start a war or hijack a thread. Just my .02. Hopefully someday I will get to test drive the 100 series and change my opinion.

Now, looking Bruiser's signature.....he owns a car with my favorite engine on the planet....the rotary. Way to go Bruiser! I'd LUV a 3-rotor rotary (they don't import them) in a sports car. I'll take the new 2-rotor Renesis in the new Rx8. Gonna get one of thoese Bruiser?[/QUOTE]

Shotts,

Thanks for the comment on the Rotary. It is a fun car to drive (not that I drive it much). The amazing thing about the rotary is that it has no maximum RPM where the engine runs out of breath and poops out. The faster it turns the more power it makes. It feels TOTALLY different to drive than a piston engine.

Anyway, Mazda did make and import to the US a 3 rotar wankle in their 3rd generation RX-7's. The engines were plagued with MANY problems and proved to be no where near as reliable as the 2 rotor wankle. There is a very simple inherent design flaw in a 3 rotor wankle. How do you get the middle rotor on the crankshaft? Either you have to split the crankshaft or the rotor. I forgot which one Mazda did, but it didn't work.

If you are ever in South Jersey, look me up and I will let you take it for a spin.

Gauge: You didn't offend me. That's a hard thing to do.

I made that "denial" statement, figuring that you might be one of the many "100 haters" (because they don't have one). Obviously you're not.

The tread was focused on buzzy vs smooth vs whatever motors. One ride in a 100 is enough to learn that it's engine is leaps and bounds ahead of the 80's in this regard. If anybody wouldn't admit that AFTER driving/riding both trucks they'd be in denial.

Amazing to hear a Ford with 325K on it. Amazing! Those days are gone for Ford, huh?

.

The 3rd Gen still was a 2-rotor 13B rotary, just twin turbo. Only in Japan did they offer the Rx7 with the 20B 3-rotor motor.

was playing with the rig today in the mountains and came to the conclusion that the buzziness is unequivocally related to the drivetrain as I noticed that there is a perfect match between vibrations felt in the xfer case shifter and what can be heard. No vibration at all felt in steering wheel, pedals, and various interior parts, but when I touch the shifter it's plain as day. Same pitch, same dynamic changes, everything. Gotta be the engine...

Buzz off?

I'm buzzed right now. Drive from Knott's Berry Farm to Tucson. YUCK!

My '93 has this buzzy/throaty thing too, and I kinda like it

At idle (when it idles properly ) it is very smooth and quite. When I had it in for the 150k service the mechanic said it put it up on the lift, left to grab some parts, and came back and proceeded to push the gas with his hand. He was suprised it was acutally running, he thought it was off

That being said, the 100, or at least the few that I have driven, are quieter than my 80. Be it engine design, interior sound insulation, a the fact that the 100 didn't have 150k on it, or a combo of all 3, it was not as load. Not to mention that it will easily walk an 80 in an acceleration contest. (I still prefer the more sluggish throttle response of the 80, especially when compared to the v8 LX, easier to control in low speed/low traction situations imho).

But of course this is all relative anyways. After hopping out of my dad's powerstroke, the LC feels smooth, quiet, and easy to manuever in tight spaces
