[V8] timing belt and other horror stories

[Paul Jager]

Did the timing belt on this one found a flattened (out of round) tensioner 
pulley probably due to abuse on installation, the waterpump bearing was 
pretty loose/bad and that was with just 50K miles on it. Got it just in time 
phew.

The SS exhaust tips in this video (we make them) actually fit on the Audi V8

The driveshaft of the 928 is very similar to an inboard boat. It's about a 5 
foot steel shaft with two pinch collars on either end. The engine end is a 
friction fit collar, the trans end (at the rear transaxle) has a 
fixed-in-place groove. The driveshaft winds up and pulls the friction fit 
joint - but with memory - that is the position does not return. And it 
creeps over time putting more and more pressure on the engine flywheel 
flexplate. The Thrust bearing on the 928 is huge and can handle high loads, 
but at very excessive loads the oil can no longer sustain the pressure and 
the crank acts like a lathe on the block, chipping away metal until the 
friction is so high the engine ceases to function and the block is 
completely toasted. It takes miles and time (with evidence) before the point 
of cease to function.
