So, I had a rattling noise, searched the threads in here and tracked it down to loose crank pulley after I loosened the belt. Now, I haven't pulled the crank bolt out yet to know how bad it really is...
So if all goes well I can slap on a used balancer for $50-70 and reuse the keyway that is in there.
If things go bad, then the crank could be out of round and cause this "new" balancer to crack like the first one. Bearings are also coming out too. At that point, I'm pulling the f'n engine so I don't have to work on the ground. I can have it out in a few hours. No biggie, plus I can reflash my awesome PTS converter while it is out...
Options, supposedly I can have the crank rewelded or something to make the balancer fit tight again.
I just can't seem to understand why would my balancer suddenly come loose like that. The crank bolt is tight. I mean tight. What if the crank was under duress and will not live much longer? I have billet main caps, align honed and all that. Should I drop the pan and look at the bearings? I have an extra oil pan gasket somewhere around here. I hate dropping the pan while the engine is in the car. I don't want to grenade the engine and trash my $1000 billet roller cam and hurt my expensive Wiesco pistons, if I can avoid it.
I had a couple of bouts recently with severe knock (got out of it immediately). Would that cause this balancer to come apart?
IMPORTANT: I also noticed the sound only after I installed my RJC power plate on Saturday. During the install I noticed some oil in my intake so I cleaned it out w/ carb cleaner. Some of it must have gotten into the combustion chambers because when it fired up, it popped really loudly and then shutoff. I'm guessing this was the cause. I drove for 40 miles since that event. Unfortunately, that doesn't help things. Since I couldn't hear the rattle from inside the car, I drove it Sat afternoon and Sunday, then noticed the noise from outside the car and then started investigating on Sunday night.
Any insight appreciated and thanks for reading my longwinded post,
Jim
