How many gym sessions and steroids did it take before you could remove them, Janis?!!

[hunker7]

I am pretty sure these are foocked.

[hunker7]

What is the price of them?

She just needs new bushes ASAP. Went for budget choice as Albert's polybushes are on the parts list. Running issues are still there, but that's being sorted....hopefully.

[hunker7]

Nope no need to but worth it if you can.

I guess I'll leave that to when I decide to upgrade to many powers

Thanks for the info guys, so if I am not upgrading engine there is no real need for balancing?

[Error404]

A perfectly balanced engine puts the minimum stress on bearings and components and thus will have a better life expectancy, especially when driven harder. It also will rev more willingly and you can safely use more revs, although the rods re normally the limiting factor in terms of revs (not considering the oil pump).
Obviously the engine will drive more smoothly. Factory engines are balanced to a point but in mass production corners are cut for cost/efficiency of production and there are good improvements to be had by having your rotating assembly properly balanced. If you are changing any signifcant parts of the rotating assembly i.e. rods, pistons, flywheel etc you really should get the re-done to preserve the balance. In short its not essential but IMHO foolish not to when you have the cost of a rebuild on your hands you may as well do the job right.

PS: the harmonic balancer has nothing to do with balance it is there to damp harmonic resonance that would otherwise put strain on the crank (potentially crack it over time).

[geneandbolly]

Don't these engines have harmonic balancers, a bit like the old big block V8 engines?
I remember the Mopar 383 had one and it was common for the anti freeze to leak out of the water pump and rot the rubber on the balancers and you'd end up with an engine that would vibrate like hell!!

That's more expensive than I thought

Might be a daft question, but why exactly would you balance crank?

If it's not balanced your engine would shake itself to bits I'm guessing

[hunker7]

I am looking at gearbox mounts, but VagCat shows several PN's, so what gearbox was fitted to '93 S4?

If you are still up in the Leeds area these guys do a great job at reasonable money. Bot myself and my dad have had major engine work carried out there and it been perfect.

Polishing the bearing surfaces on a crank should be about 50 quid. Balancing is a different game. Talk to jp and jnl racing. About 350. He would need your rods and pistons bearings pullys and flywheel etc.
