Upper Balance Shaft IMP!!!

I need some advice! Last night i was driving and my engine all of the sudden sounded louder and started vibrating really harshly so i took it into a shop this morning and found out that my Upper Balance Shaft had seized. they said it will cost between $1200-$2400. i cannot afford that. i was wondering if i should try selling it as is or parting it out, any other suggestion are gladly accepted as well... thanks

fix it your self. Just take it apart and replace the bushings and find a used balance shaft. Or I have a engine from a late 85 944 Will sell for $600 plus shipping. Then you can just swap engines

The upper balance shaft is pretty easy to get at...it seems.

Sounds like the shop is trying to give you the shaft............................................. .................................................. .................................................. ...............(i kill myself sometimes)

Sounds like they are trying to sell you new parts because labor shouldn't be more than three or four hours. Look for a shop that will install used parts and search for the parts you need on the forum. That will save you a bunch.

Upper shaft seized ??? Thats not very common....

Uhmmm ... did the balance belt snap or just get stripped? It must have? your lucky the timing belt did not get caught up.....

I am pretty sure the balance shaft bearing bridge is machined with the block? I am wondering if they are thinking that they may need to pull the engine and have it machined ?

If thats the case its probably cheaper to find a used engine and swap it out.

Good luck.

Biggest suggestion here is


Get a second opinion.

Balance shaft failure is rare, you need, as noted above, a second opinion. If the bearing in the block that failed, you will be buying another engine, as all the metal pieces are now distributed through the oil system and to repair the rear bearing housing (in the block) means major engine disassembly. You need to get a written estimate of the repairs.

CrUeL-

I have an upper balance shaft and cover for your engine. If it turns out that all you need is the parts and not a new engine, PM me and we'll work something out (really cheap). You'd need to get new bearings and seals for it, of course.

I say you tow it home, pull the balance shaft seal and take a look at what is going on in there.
You have a decent chance that you can just replace bearings, seals, and a new balance shaft and be on your way.
Worst comes to worst, you can swap the engine. It is not that hard, and there are plenty of people here that would be glad to help.

I remember reading some where that if you disconect the balanced shafts you can gain 7 hp. The down side is the motor shakes like a mother.

It'll be cheap if you can do it yourself; new balance shaft belt, new bearings, some Loctite 574 to seal the cover, new seals for the shaft, and about 3 to 4 hours labor. Parts shouldn't cost more than about 75 bucks or so through Pelican Parts.

If you don't feel comfy doing it yourself, I'm sure that AFJuvat or SoCalDriver can give you a good figure on what a shop would charge for the job.

There is a lot of info on this forum about how to properly install and tension your belts. Pay attention to the procedures if you do it yourself, otherwise you'll join the Order of the Bent Valve.

Yopu also have a PM.
