And another reason to change the oil in this unit very, very regularly (ie every 3k)

Ah.........lovely echoes of the Senny!!  

I miss the chains!! :'( :'(   Why do cars still have to be fitted with 'rubber bands' instead of sensible, long lasting, chains?? :-? :-? :-?

Because the rubber bands are so much better. The rubber bands don't stretch.  The rubber bands allow Vx to have that silly 20k servicing. And still cheaper to replace 3 times than the chains are to replace once.

Yes maybe, but my old Senny, at 250k on the clock, still had the original chain fitted and the Vx dealer (then an excellent one) told me that they rarely replaced the chains; just keep the engine well oiled! 8-) 8-)

The engine was still producing top speeds of 145 mph. :-* :-* 8-)

So you've said before ........ I ain't convinced.  ;)  ;)
You come across more cars where the rubber bands have snapped than you ever did with chains snapping. I ain't coninced over the stretched chains either ... they sit it their own oil bath.  :y

And we've all heard of rubber band cars doing 150k on same band ;). And as those same bands will never stretch, they too will be capable of any performance it had when newer...

Generally, the belts don't snap, its normally a bearing that gives up the ghost ;).

Generally, the chains only snap with extreme age - particularly if the car is well maintained - but the plastic chain guides are more problematic.  Unlike belts, all chains are prone to stretch.


I know some people look back on their old Senators with rose tinted glasses, which is nice, but I think everyone would have to agree the Omega has a more refined, more drivable, equal performance engine, certainly handles much better, and is most definately a better ride for cruising :)

Some of us may disagree with that, like my parents and friends in the past!!  When I swapped from the Senator 3.0 CD to the Omega 3.0 Elite they all said how much they prefered riding in the  senny than the miggy!! ::) ::) ::)   It quite put me out at the time!! :'( :'(

However, of course the Omega is a far more advanced car on the Senator, but what would have been really wrong in fitting a chain to their engines??  The cynical part of me believes it was so GM could enjoy far higher profits from after service sales, let alone the odd new engine or so! ::) ::) ::) :D :D ;)

I would have a belt over a chain every time.

I much prefer to know where I am with the state of the timing setup.

The chains stretch, the guides wear and they do snap, most are pretty buggered by 100K miles.

The only benefit a chain has is that it does not need changing every 4 years or so.....big deal, it still needs doing every 100K miles idealy and its often a bugger of a job!

Its easy, a chain setup on a quad cam V engine is a bloody nightmare, all simplex, loads of tensioners, timing issues the lot.

Belts are also quieter.

And GM dont make big profits from aftersales, the garages are the ones that benefit.
