just after some oppinions. if someone rebuilt the bottom end i.e(rings brarings and seals) and didnt replace the timing chains would this be a dodgy job?
just a family 'dissagreement'
the engine is an 18rgu
thanks

not trying to weigh into family discussions, but i'd say dodgy.
the pistons/rings last longer than the timing chain 9maybe twice as long at least, if not three) so to not change it means you have to open the engine up earlier. if you replace when the bottom end is done, it is also a shite load easier too as the motor is out of the car....

Agree with Stewart on the life expectancy of the timing chain.
Don't just replace the chain, do the tensioner and guides aswell. Buy the whole kit from Veales or Repco etc. Cost like $60 to $90 but is worth it in the long run.

I disagree.
If it doesnt need replacing, why replace it?
Just beacuse its an engine rebuild, doesnt mean EVERTHING, needs to be replaced.

YES, unless they(chain AND sprocket) only have a few K's or less on them.

Obviously if the chain, tensioner and guides were only done 1000kms or so before the engine was pulled for the rebuild. Then yes, there is not particular point in putting in a new ones.
But as MOST motors that are pulled out to be rebuilt, have not had the chain done. Then yes it is advisable to do the chain while the engine is being rebuilt. As the 18Rs have a tendancy towards having 'noisy' chains in older motors, the whole $60 to $90 while the engine is out is a hell of a lot easier than trying to replace the chain later in the car.

looked at the engine this morining, and at the very least it had a blown headgasket. and the engine didnt rev past 6400 i think it had a valve bounce problem. what do these motors rev to? he also claimed that it was standard (apart from extractors/exhaust) yet it put out 80kw (claimed) at the wheels. does this sound correct?

Extremely dodgy and you'd look quite the fool when the chains are rattling away at 10000 km after your rebuild. It could be worse though - one might snap and you'll find out what an interference motor is.

I will just sit back and eat my words 
I apologise about the price I qouted, didn't read the 'G' bit. Expect to pay a hell of a lot more for an 18RG timing set. If the guides are in good nick then just do the chain.

which is prolly why it wasn't replaced in the first place ie: cost.
