How does a harmonic balancer leak?

How does a harmonic balancer leak?

When the harmonic balancer stops balancing it causes an ethereal dispersion affect at the balancer shaft, which is inserted into the front hole of the crank cover connected to the ignition timing tab associated with the pulley notch that spins so fast at idle only a large-eyed timing light can see it, and after a long time the suspected lack of lubricity during intercourse between the balancer shaft movement and the tightness factor breakdown causes uncommon friction and a slight grooviness in the shaft allowing crankcase pressure to push droplets of heated harmonic balancer oil out on the inserted shaft and then dripping a short distance onto the perpendicular area just below the harmonic balancer.

This highly disconcerting failure may be prevented with a prophylaxis sleeve over the harmonic balancer shaft covering the grooves and carefully inserting a new extra tight self-lubricating harmonic shaft-gripper into the crank cover hole.

At least that’s what I was told.

My engine has leaked oil from day one from the front seal.  I am told this is because the seal wears a groove in the harmonic balancer.  I have a couple options to stop this leak.  Been told a seal for a 85 Celica, thinly shave off part of a new seal, a speedy shim, or a new harmonic balancer.  I would rather do it the right way, instead of a band aid and hope it lasts a long time.   And Putney has them for $100.

You need to buy this thinner seal:  90311-45014 Type-T  You will be good for another 200K or so until it wears another groove.

Something to think about. 


Well, I got it running.  We had the timing dead on at 5*, so adjustments there.  Once all the oil and lubricants burned off, we noticed a couple things:

1.  There is an exhaust leak.  Sounds horrible, to me.  Worse driving.
2.  Need to check the valve lash.  There is one that pretty evident.  We checked them, but one is amiss. 
3.  Radiator has some pinhole leaks.  I been wanting the larger V6 radiator.  They carry the cheap alum/plastic ones in town for $116. 


But its done!  We had some WTF is that sound moments!!     One of the belts was making a weird noise.  Sounded like a bearing going out.  But once we put some spray on it, it went away.

Well, I got it running. 

Hey Cheesemaker,

Congrats!  Glad to read that you got it running!  Good job!

Several Toyota engine builders have stated to recheck the head bolts, but when I did the head job on my 22R, after 2 days of driving my truck to work, I rechecked the torque on the head bolts (I re-used them) and they didn't move!

For your radiator leaks, if you want to stop them for now until you get a radiator, you might try a 1/2 tube of AlumaSeal.  https://www.goldeagle.com/product/alumaseal-radiator-stop-leak-powder

What did you do for your exhaust leak?

What did you spray on your squeaky belts?

Gnarls.

[Cheesemaker [OP]]

I will recheck the head bolts at a later time.  At the same time I will double check the valve lash. 

I refuse to put anything in a cooling system that isn't coolant.  I made that mistake years ago with an old Nissan.  I will just get a new radiator, and put this one up, fix the tubes, and hold it as a spare emergency radiator.

I have not looked into the exhaust leak yet.  I just got it running late last night.  My buddy couldn't come over Monday due to an illness, and he finally stopped by late last night.  We got it running, it took about 4 starts.  Timed it.  Brought it up to temp, I drove it around the block, and parked it. 

As for the belt, he barely put any PB Blaster on it, and gone.  Must have been some contaminants on it.

Ok, thanks.  Yeah, I understand not wanting to put any weird stuff in the radiator fluid.  I'm a skeptic, but I have used AlumaSeal in the past, and have a couple interesting stories about it.

Please let us know how she runs when you get her tuned up.

AlumaSeal is good stuff, also known as Silverseal.

Alrighty, another awesome phone call with Putney.  I swear the dude is awesome to talk to!  Kinda reminds me of calling Marlin and getting lucky to talk to Dave. 

Ordered the exhaust manifold gasket, and the longer exhaust studs.  I definitely wasted money buying the Fel-Pro kit!  I only used a couple gaskets out of it, and the exhaust gasket failed right away.    

In the next couple days, I will be picking up a new radiator, a v6 one.  Pulling the valve cover and readjusting the valves again.   I would today, but I have to sit by the phone, so I can go get my step dad from the hospital after giving us a scare yesterday.     All due to medicine reacting to other meds.  He was blacking out.

Is 22RE Performance selling the Toyota factory head gasket?

[Cheesemaker [OP]]

Yes they are.   

[Cheesemaker [OP]]

So, update time!! 


Well, I haven't worked on it for a week.  Between work and mainly wife been sick, I finally got to work on it today.  Which is good and frustrating.  I finally got the 22R style exhaust manifold on.  But it took some doing.  I had to smooth out the face.  A long file, and a belt sander to smooth it out, and eliminate all the surface rust.  I used a good straight edge to check to is how true it was.  But with the graphite coated gasket, I wasn't too worried about small imperfections.

Put it on, and started putting on washers and nuts.  When to start them down.  But there was some casting preventing me from using a socket on the middle two lower ones.  WTF?!?!?!  I tried a OEM nut, nope flange hits.  Off it came.  Dremel time!!  Got it all ground down and all sharp edges all smoothed out.  Torqued up in 3 stages.  33# on the dot!  O2 sensor.  WTF???!!!???!!   Bottoms out about an 1/8" away, and won't go any further!!      This freaking exhaust manifold is fighting me the whole way!!!  So, down to the parts store, I go!  Nobody had any on hand.  And their freaking computer doesn't tell them squat. They only give overall dimensions.  Not the important ones I need, like the depth of the sensor.  I have to order them in.      At this point, I am about to buy a long bit dremel stone and grind away.  I can't, I already put the manifold on!!  And I don't want to risk sending grindings in the exhaust ports.  There might be zero risk of doing it, but with the way things have gone!  Don't risk it!!!   

Why didn't I test fit the O2 sensor??  I didn't need too!  It was a used manifold, so I figured it would be just fine!   

So, Advanced Auto/Carquest has a Denso and a Bosch generic coming in tomorrow morning.  I will go try them out.  Which ever one is shortest, will win!! 



So tired of having 3 parts houses and neither one have the parts I need, and the only good parts I have bought was from Putney!!  And a guy at NAPA said I can't get a new o2 sensor, because it has to matched and programmed to the ECM.  I walked out on that one, and its time for a big DRINK!!!     

[emsvitil]

I kinda sorta remember that the O2 sensor fit in a stepped hole that's inside the manfold.
 

So it might be O2 tip diameter.
 

Or it's just alternative memory.......
 

[emsvitil]

Or if this is the Toyota flanged O2 sensor, just make a spacer flange and use 2 gaskets......

[Cheesemaker [OP]]

I did run across a post on Pirate about this same situation.  And it was suggested that they should make a spacer and 2 gaskets.


I have two coming it at Advanced Auto Parts, OEM Denso, and a generic Bosch.  The Bosch looks smaller, but we will see tomorrow.

[Cheesemaker [OP]]

IT'S ALIVE!!!!!       

And I feel good about it!!

[emsvitil]

 



What did you do about the O2 sensor?

[Cheesemaker [OP]]

I just bought the generic Bosch sensor.  All I had to do was crimp a wire on the pigtail it comes with.

My truck is pissing me off!! 


It's now leaking coolant somewhere around the intake now!!     

[:)bestgen4runner]

I suspect one of the small Bypass hoses under the intake. 
easy fix and not expensive

[Cheesemaker [OP]]

Ok, I drove it to work today, I only live 3 miles from work.  And when I got home, I popped the hood and looked around while the engine was running.  And I could see it dripping.  And I rolled a hose, and I see I have a pin hole leak.  Its in the hose that wraps around the thermostat housing.  I have a couple others that are showing some wear.  So I will be ordering from Putney again!!

Throttle body / IAC coolant by-pass hoses (OE)  $54.00 for 1985-1988 EFI trucks

[emsvitil]

$54, that's crazy.....

I'd just use some straight hose, cut to fit........

It's not like you can see them.


And I only remember 2 hoses (to/from IAC)

What's crazy is the factory hoses will last 30 years.  They get hard and will crack when you go to remove them.  I tried to put a piece of straight hose in place of the factory hoses and it only took 10 seconds to figure out "that  ain't gunna work, Scooter."  They are formed to fit for a reason.

"$54, that's crazy....."  Yes...those little Japanese are VERY proud of their parts!

That's just my experience.

That's why you go long with big loops..............

For sure short with little loops won't getter done!

[Cheesemaker [OP]]

I will try some store tubing and see what happens. 

[Mudder]

I used gates green stripe for hoses.

[Cheesemaker [OP]]

Alrighty, I broke down and bought the hoses from Putney and installed them.  No more leaks. 

I swear, this truck was gonna break me.  Get something put together, find a issue.  Order parts to fix issue, wait a week.  Parts arrive, and finally replace parts.  Then find something else, wait a week for parts! 

Well, I have finally been driving it every day now for this week.  So I have been without my truck since the beginning of January.  Its nice to be driving it again.  But since we replaced the head gasket, it has developed a vibration.  It is very mechanical feel to it.  That wasn't there before.  But it runs good tho.  We will see what long term gives me.  I wish I had a spare motor so I could have swapped it out and done a complete build on it.  I wish I could have gotten a adjustable timing gear.  But I spent too much $$ already. 

I also had to pass up on a 84 extra cab 2wd that just needed a new head, for $450!!  Good condition body wise.

I can relate! 

Passing up that 84... oh crap! 

Vibration...?? What kind of vibration? Engine, tranny, or chassis? At what RPM? All the time or intermittent?
