Drove home from work with a damaged belt and...

[AznGouki]

I just supercharged my car and the belt on it was damaged and I really needed to get to work so I drove with it thinking it should be fine. Got to work and 1/4 ribs snapped and peeled off on the road somewhere. I just drove back and half way I just got this feeling and load and be hold I hear a squeeling from the engine so I pull over and there is oil all over the passenger side.

I have no idea what just happened so if somebody can please shed some light. I drove with the supercharger on off.
And the belt is still in once peice.

which supercharger? belt connected to crank, water pump, alternator, a/c as well as blower?

[1NZYaris1]

Sounds like an oil seal ie crank , timing chain cover , or beather pipe.
it's hard to say without seeing it , try putting up some photo's :thumbsup:

[AznGouki]

Blitz supercharger. Belt connected to crank, water pump and alternator. I don't have a/c.
I honestly have no idea how I blew oil. I'm gonna jack the car up later and see if I can source out the oil. Maybe it came from the dipstick column as I let it dangle after the install. That's the only thing I can think of.

I'd post pics but it won't really help much. It's all over the entire passenger side(where the pullies are) and the back where the ecu is mounted. Also a small small puddle where the plastic under panel is(passenger side as well) and the oil is rolling down and collecting on the oil pan nut where it drips.

[ChinoCharles]

Post up some pics. I'm sure we can diagnose.

Not to preach, but NEVER drive with a damaged belt. All sorts of bad things can happen.

[AznGouki]

Pics are up.

[AznGouki]

Yeah I know. And I just realize that I forgot to top off the coolant that spilled during the install. But if I were to go into the red zone of the oil temp wouldn't a light come on the dash? I guess that's some more info there...could be overheat, and I found the 1/4 of belt that I thought fell off on the road when it snapped. It was on the control arm of the passenger side and a thread's worth is wounded on the crank pulley. I just topped my oil off a bit and started up the car.
The temp "cool" light went off meaning car is at optimal temp and I get it a few revs and no oil is leaking.

Let me know if you need more pics or pics of the car at a certain spot.

[1NZYaris1]

Check your DIP STICK .:thumbsup:

[AznGouki]

Check my dipstick for level or connection. But I will do just that.
Just checked the dipstick area. It's ok. The front of the engine has no oil. The mess is all in the back.

[lunjiaow]

You could wash it off. Then drive it again then check where its coming from. You did mention something about the belt wounding up around the crank, maybe its damaged the crank seal.

[Tamago]

looks like the crank seal is leaking, how tight did you make that SC belt? you could have possibly destroyed your crank seal by over tightening (which also means the bearing inside is trashed)

[AznGouki]

I wiped the oil off to the best of my ability. I'll take the fuel controller off and clean it manually. If you look at the pic up top of the crank you can see a thread wound up. That's pretty much it. The rest of the 1/4 belt was laying on the control arm.
I actually didn't put that much tension on the belt for fear that it would snap.
Like right now it's not leaking or anything. I'm changing my oil and topping off the coolant for fear it might be overheat.
I had to 2 spacers to make mine align properly and I drive a 08 LB.

[AznGouki]

Ok I just changed the oil with silky smooth amsoil and I found the leak. Well not pinpointed but it's definitely coming from the Crank. The oil makes contact with the Crank pulley and that is how it's sprayed it all over the back. The rate that it drains with the car on at idle is 1 drop every 2-3 seconds. Am I royally screwed? I think I'm gonna bring it to the dealer tomorrow or do you think I can fix this? I'm gonna take off the Crank pulley tonight and see if I can pinpoint the exact part.

[Morgan]

Well... from all accounts it would seem to be that crank seal, but I doubt the dealer is going to fix it for free under warranty work. As much debate over the law that protects people who add mufflers and still need transmission work, they have a pretty good case against you for not trying to fix that leak.

Good news is removing the engine is fairly easy... if you are capable of the s/c install you are a cherry picker and a good impact away from dropping the engine

[AznGouki]

Yeah, gonna drop the car off at the dealer in a couple hours. Will see what they say about the crank leak. Other than that, the supercharger install went smooth and wasn't too bad at all.

[thebarber]

lol, taking it the dealer w/ the s/c and pulleys on the car? lol good luck at getting warranty work done......ever

[Tamago]

classic example of people asking for help then not taking the advice ;)







good luck OP

[ChinoCharles]

I would NOT drop that at the dealer! LOL

[Tamago]

Yep the dealer is gonna laugh at you when you say you want that covered under warranty, even though the seal was probably not seated properly from the factory or was just bad and the adding the compressor pushed it over the limit. You are the only blitz owner that has had this problem as far as I know.

I do not have the lite crank pulley installed on mine, even though a lot of people praise them and say they won't hurt anything, I don't like the idea of not having a dampened pulley. Keep us posted, I am curious how much the dealer is gonna charge to fix this.

in what way is the stock pulley dampened ?

[Tamago]

In what way is it not dampened?

it's a solid piece of metal.

[Tamago]

You cut it in half and look at it, better yet if you can prove it to me that it is not dampened I will give you a brand new NST lite crank pulley!

what is it dampened with, rubber?

[Tamago]

Composite

lol :laugh:

[Tamago]

most inline engines are internally balanced. harmonic balancers are for "V" configuration engines

[Tamago]

i have no need for a piece of shiny aluminum. prove to me that it's dampened and i'll send you a dollar ;)

[Tamago]

If you tighten the belt tight enough to mess the seal or bearings up in the crank, you would be lucky the engine would even turn over and if it did start it would certainly shred rather quickly.

did you miss the part where the belt got shredded?

[ChinoCharles]

"I'm smarter"
"No, I'm smarter!"
"Nuh-uh!"
"I'm totally so smarter"
"No, I'm totally so super duper smarter!"

:laugh:

Don't take it to the dealer. Get your parts from Toyota. Do you have a very, very handy friend?

[ChinoCharles]

Well he could take it to an outside shop. Might be worth it to pay a premium to not have the dealer see what your S/C just did to your engine. I would be hitting my friends up personally, but this is Ohio and toddlers are gearheads here.

[ChinoCharles]

Yeah he could do that too, but I would make sure it is a trusted shop.

Well DUHHHHHH. :wink: :biggrin:

[AznGouki]

Wow an instant 2 extra pages with nothing useful at all.
I do think the seal may have been weak to start with and the supercharger just pushed it over. Does that mean it could happen again? I sure hope not. The first belt was wreaked not because of the massive power of the supercharger. I have a thread asking for help on my install but to cut things short, the tension pulley as I call it or the extra pulley that comes with the kit was not spinning due to contact with a bolt. This created heat and wreaked the belt.

Took it to the dealer, told them the car is modified and I didn't expect to have warranty coverage anyways. Dropped the car off at 7am and handed over the keys, 9am they give me a call and tell me the cost of fixing the crank seal leak and 10am they call me again telling me to come pick my baby up.
280Cad is cost incurred.

[ChinoCharles]

Wow an instant 2 extra pages with nothing useful at all.

Rude.

[AznGouki]

Sorry ChinoCharles but even Echo HRS had to come in and stop the bickering. All it was for 2 pages was a war over the lite pulley.
I do appreciate everybody's help though. I'll be picking up my car in a couple hours. I need to find a ride down.

[cali yaris]

Glad you got it sorted out!

[PETERPOOP]

I wonder how long the guys at toyota were driving your car around before you pick it up.

[cali yaris]

He had a positive dealer experience.

[cali yaris]

ok let's settle this crank pulley argument.

Here is the 1NZ-FE stock crank pulley (from my car), clearly showing the rubber (or "composite", but seems like rubber to me) ring embedded in the pulley.

:biggrin::bellyroll:
just couldn't let it go :laugh: :bow: :bow:

[cali yaris]

^ yeah I know. Sorry. "We now return you to your normal programming".

[AznGouki]

The person I talked to was really friendly. She said even with mods it might be covered but it wasn't. Job got done fast so I'm gonna go pick it up now. I left the switch on "off" so they may have taken it for a spin only to realize that it's not quite as fast as they were hoping.

[PhilD424]

Seems like the OP over tightened the belt or put that crank pully on wrong. Reason why the belt broke was most likely because he over tightned it and because it was so tight it messed up the seal. Sucks to be him. This is a perfect example of why you shouldn't get into things if you don't know what your doing.

[ChinoCharles]

^ Also rude.

[PhilD424]

^ Also rude.Not rude, its the facts. It was ment to inform people and stop people from making the same mistakes. Sometimes the truth hurts. Man up and learn from it.

[AznGouki]

Sorry camelll I didn't mean to offend you man. I was just in a fritz and looking for a guide to fixing the seal on Crank. I appreciate everybody's input. Fact is I don't know what really caused the seal to break. The amount of tension that I put on the belt is no more than how much tension I have right now(dealer set it). But everything is good now and all fixed up.

[greatnowhere]

in the photos that you posted it appears that the cord from the failed belt wound around the crank behind the red pulley. if that bit of cord rotating with the crank was against the seal, i would think it would damage the seal in no time but just from looking at your pictures i would think that removing the pulley and replacing the seal would not be too hard. good luck
jim

[lunjiaow]

Congrats on fixing it. You should have replaced the seal yourself, would have saved yourself a lot of money and time.

ahh thanks for the pics, Garm... I was about to go dig out my old one to see if I could see any dampening, for my own edification.:biggrin: I really don't think a NST light or 10% underdrive pulley would have a problem with vibration. Being lighter weight and precision machined, I can't imagine it vibrating worse than the heavy stock one... :iono:
