Re: Is this a serious problem?
This problem happens because the balancer is busted. Note the bulging rubber between the two rings of steel. This is supposed to be vulcanized so the two don’t move. If they don't move the timing mark stays in the same place. When they do move, due to age and what ever, the timing mark walks.
You have to get a new harmonic balancer. End of story.

I guess it is only a problem if you are trying to get correct timing....

Timing doesn't affect piston travel as far as i know, example: you can't blow the piston out of the top of the head....is this what you mean serv?

Re: Is this a serious problem?
the harmonic balancer not only provides timing marks and refrence, it does what the name suggests, balances out smaller vibrations that occur. there is a viscous fluid inside, and inside the fluid is another metal plate that somehow spins to counteract vibration (i dont know the exact science, and this is most designs) but if the balancer is shot there might be increased wear due to uncontrolled movement. you probably wont feel it too much (if at all) but running without a H.B. isnt good for the engine.

Re: Is this a serious problem?
I am pretty sure stock balancers dont have fluid in them. You are speaking of a fluid damper. Anywa, the only reason ithought about keepiong it is cause it is lining up perfect. However, Im now starting to wonder if this balancer couldve cause the front seal to go bad and vibe the pick up tube out. These are the things I found wrong when I pulled themotor last month. I am picking up my new one tomorrow. I really gottqa stop taking the little things for granted. I knew about it last rebuild and blew it off. Live and learn right? I ordered my turbo from Waller today so hopefully it will be running by this weekend.

Re: Is this a serious problem?
A fluidampr is fluid filled as you say...it balances at all rpm's....what I saw in the pic is a rubber liner stock type that spun....it would be kinda like moving the weights on your tire/wheels around.....they would shake at certain speeds thereafter......I would imagine a stock balancer that already spun once should immediately be replaced because if it slipped once, it should be easier to spin a second or third time then the outer part might disconnect itself from the inner portion....it could fly apart....I run a fluidampr on my sy with no problems yet....some people say they roast then fail because of our hot crossover pipe.....The stock balancer on my ty475 slipped at some point and I felt an engine vibration at around 3500 rpm....I would replace any stock balancer that slipped at all, period....

Re: Is this a serious problem?
Which balancer are you guys installing and is it keyed so you just pop it on? Are all original SyTy motors balanced the same so installing an aftermarket damper balances them all? I know, dumb question, but I'm curious. My stock balancer is still where it should be at 70K original miles. Did a TDC check with piston stop last week and the notch/groove lines right up with the 0 mark.

I got mine from Checker. It was $80. Autozone had it for $60 but I got my turbo from Waller today and didnt want to wait til Monday to get hte balancer as they had to order it. Dont know much about the fluid dampers but am pretty sure that as long its for a 90*v6 or a 4.3 it would work.
