well now im totaly f***ing pissed! we got the new HB, got the car running and all seamed well. but just like before when the car got warm it started running like a powerless bag off shit, im so pissed right now :x

Refer to the Fake Canadian's fiasco with the Harmonic Balancer dance.

Where did you get it from, and what's the part number?

it came from a jobber and it did have the wrong rings on the back, so they were simply swaped

:?:

They swapped the old rings to the new HB? How about the offset? Tooth cut offset to the keyway?

That was a bad idea. Get an OEM unit on there. AC Delco.

If i can return the non OEM new one, ill do that and get the Delco one ( $130 more :( )


but in the mean time what else could be causing this issue taking into factor everything i havent replaced

First time I've seen this thread too. Shoot me. :lol:

You've made a lot of progress! But I'm wondering about this HB....I had a fiasco with getting the right part for mine. After only a couple seconds after startup I noticed something was wrong. Weights are different for every year.

Good luck figuring this out! I'll search for my thread...

FWIW...part numbers are in there somewhere.

http://www.bonnevilleclub.com/forum/...monic+balancer

EDIT: Actually, the part numbers in that thread don't include a 92....your would most likely be different from any of those stated.

Pete, your part numbers may not work for Peter. My 93 and 95 are different.

Yep, just edited my post. I thought the 92 part # was in that thread, but it wasn't.

Consider yourself shot! :lol:

so what your telling me is that not only are the rings in the back different but ther weighted differently aswell? so even if the rings was put in the new one and lined up perfect there would still be a problem?

Yes. And weight equals mass. So when you romp on it with a heavy balancer, the rings lag. But on a light balancer, they don't.

You need a year-model-specific balancer. It MIGHT be your problem. Hard to tell.

just got off the phone with my mechanic, he said that there was no way there was a weight differance that would cause this.

And givent the curcumstances i would have to agree because i had this identical issue with the original factory HB and its not liek i always had the problem, it only started last April (going down to NEBF) before that there was never a problem

One of the wrong parts I installed on mine which was allegedly both for a 94/95 was in fact weighted differently. After getting the right number 594-161 (IIRC) I checked my ORIGINAL HB to the new one and the weight was the same size...but when checking the new one with the wrong part I had installed, the weight on the wrong one was much larger (looked to be 3 times the size).

So you said the HB was from another car? What year was it? I assumed you took it from another 92...but if not that could be a problem. And since you swapped anything at all off the HB, you must have had the wrong part IMO.

Right away I noticed my car idled bad with the wrong HB. You said after yours warmed up it ran poorly? How did it idle?

Since you just reinstalled a new engine it could be something else...but if the wrong HB is on there that's a start.

Idle is fine, drives good on Light throttle but is a real dog on mid-heave throttle :(

OH and im getting KR like theres no tomorrow
i saw 7* on a small blip and i hit 20* and a small punch :x

BUMP.



you guys think the KR issue might be the PCM needing to learn or something?

I wish I could help. Given it being a newly installed engine, it could be a few things. I hope you get it running well!

That's a similar problem that I am experiencing with KR.....not affecting power that is quite strong.

You may have a fuel issue. :?

not sure, my Fuel pump is new and the filter has only 10-15K on it. although i wasnt happy with the look of my Injectors, i do have a set coming from FIE soon :D



anything else guys?


I know im being a little premature given i only have 6km on the motor (no plates to put it on the road) but i can just tell its not right.

even when cold the car feels lik eit has bad turbo lag :x

It's tough to tell Pete. The distance thing keeps us from checking the obvious.

Get a scan tool on it, get a fuel pressure test. And if you'd like a suggestion, put the factory sized pulley on there. Once you get it running good in stock form, then change down.

Meanwhile, the computer is trying to learn things, and at the moment..we have no idea what it is seeing.

On the HB, if the motor seems unbalanced, then it's the wrong balancer. If it runs smooth... it's probably going to work.

yeah i was thinking that going stock on the pullie might be a good idea for now.

i will be doing fuel tests and ill get a new Fuel filter just to be safe.

As for the HB i realy think its the right one, the motor idles just fine if you ask me, ill get a vid tomorrow (no cam today :x )

Read this thread, even though it's long:

http://www.bonnevilleclub.com/forum/...289&highlight=

The end result ended up being the harmonic balancer. Don't discount the idea of it NOT being the HB.

I read that whole thing, what you describe isnt quite like what im having, yours idles liks shit, mine idles fine, it just has no balls when it gets warm/hot.

heres a list of whats been done since the issue first happend last april.

things i havent changed

Do you have any pictures of the new/old balancers? I'm primarily interested in the positioning of the holes that hold the rings onto the balancer in relation to the keyway. If they are identical then this shouldn't be a balancer issue, the only problem balancer related may be a vibration (and you say there isn't one). That should solve our questions of balancers and move us onto the next stage of diagnosing.

When the engine harness was swapped over, you would have repaired any bare wires or rubbed spots. Therefore we "should" be able to rule that out.

The crank sensor.. while it appears to be performing..my own experience with one leads me to have a feeling it could be a good suspect. Especially since your issue only occurs when warmed up. Something is expanding/shorting/rubbing/doing something..to cause an issue.

PCM... heck, it sure could be a possibility. Although I believe Don would have been all over it already if it was exhibiting normal failure symptoms.

Maf...you cleaned it when you had everything apart and it's known, try unplugging it and run the engine that way. It'll set a code, but how does the car run under the same conditions that exist when the issue is noticed.

I dont have any pics for comparison of the HB's (new one was perchased/installed while i was at work)

when i did the swap, I didnt go over the harness with a fine tooth comb, but i did look i over and fix thing like tape drying/coming off and what not.


the Crank sensor I will have to take into serious thought on replacing...would a used one be good (being sure it was from a 92) I really cant see why not, considering every one is runnign on a used one if you think about it.


As for the MAF, are you saying drive it till the problem starts, then cover the sensor with something (like tape?) then see what happens?

just unplug the MAF, you can drive around with out it and see if you still have the problem, thats what i did once to try to find one of my problems.
The PCM will run on a Default setting while it not plugged in.

now why didnt i think about that? :oops:

i didn't know either until someone told me :lol:

To clarify (I know what he meant.) you can not drive around with your maf "out". You can drive and the engine will run with the maf unplugged. ;)

heres a cell-cam vid of the motor at idle (suund seans a little off from that it acctually is)
https://i15.photobucket.com/albums/a...0329071821.jpg

No bawls when hot. Poor tolerancing on internals when rebuilt? Too much expansion and friction when warm? Just a thought to throw out there.

to motors in a row, one a 6 year old GM reman, and the other fresshly rebuilt, both with IDENTICAL problems....i think we can eliminate that thery,

it has to be one on the things that hasnt been replaced yet

IAT plugged in? Try unplugging the EGR and see what happens. All your CTS's plugged in?

CTS's?

EDIT, never mind i figured it out..yes three all in

FWIW, and it's probably just the video quality, but it sounds like you also have some bad idler pullies. My engine sounded the same.

Peter...

Any difference unplugging the MAF?

worked late yesterday, and didnt have time to drive around and test. i only started the car for that vid then shut it down... i also wont be able to get to my car till late saturday of sunday some time


As for the vid Pete, the comp im on (work) has no speakers, so i cant listen to it to compare.


on a side note(most likely un related) my car seams to be running down the battery over night :x
