It's a chain. Not sure what you mean by duplex? Don't think they ever need changing.

Hmmm not sure. You could have a search on www.ih8mud.com. It's a very good source for info on petrol 80's. Not too many about on this forum...

The petrol 80's like to blow a headgasket as far as the yanks are concerned.
Nothing major though, just the headgasket that separates and pressure gets into the cooling system.
When you detect hoses starting to sweat coolant and becoming pressurised, than probably headgasket.
Simply order the parts and a days work and your off again.
Most petrol 80s that are daily driver short range commuters tend to suffer.
Other than that it's a cruiser, so well built to say the least.

The head gasket problem seems to be down to a fault with the original gasket. Some say it's down to Toyota changing from asbestos gaskets to other materials in the early 90's for obvious reasons.
The HG always seem to go in the same area, around cylinder no. 6 between the cylinder and water jet.
The updated Toyota HG has overcome this problem. So if your HG goes it's a matter of changing it to a new style one from Toyota and then pretty much forgetting about it. It's not an ongoing issue.
I wouldn't let the HG issue be a reason to put you off of the petrol model.

Not sure when they changed the design bit don't think it was until the early 2000's. Remember this isn't a particularly big issue and by no means common. It has happened to some but not to most.
Most important check to do you when you get an 80 is check the cooling system. Make sure that is working fine and you should be good for many miles. One thing to check when you do buy is if the fan clutch has been Changed to the newer one. Black one is old, blue one is new. I had overheating issues with mine on warm days when hoofing it up a hill or long climbs while laning in low range. As soon as I changed the fan clutch it sorted the problem.

Fett said:duplex is like a double row of them joined together
Duplex is the material, it's a stainless steel alloy, we use it a lot to fabricate gas flowlines offshore, it's strong & has good corrosion & erosion properties.
You're probably getting mixed up with the old rover V8 setup, the timing chains stretch on those, & a good fix/upgrade was to fit a duplex chain (usually made by Cloyes)
you both right and wrong 
I was thinking of my bmw v8 which has "duplex double row timing chain" I always thought duplex refferd to the double row.
I guess from what you say its made from duplex and has a double row. thats one hell of an engine,love it not much good off road though
rover v8's sadly have the internal spares made from indian knives and forks nowadays, the parts quality is really crappy- bit like that panorma on medical instruments

Can't remember how much tbh. Wasn't too bad though.
You should check out www.toyodiy.com. You can search for part no's and guide prices( in euros). if you are IT adept enough and access it through a german server it will apparently even give you parts diagrams...

Regarding the service manuals it's best to download the factory service manual. There is a link to it on here somewhere. If you struggle pm me and I can send you a few links to download it.

These things like HG and BEB shouldn't put you off at all.
They aren't regular maintenance to say the least.
And the repairs are easy without any time consuming remanufacturing.
Just be aware that the problem may occur and use some proactive maintenance.

Tbh I think you'll struggle to find one with the HG done.
Also if you go for an enthusiasts car be prepared to pay more...
You keep making reference to wet seals on the swivels, I'm pretty sure the swivels are suppose to be a little wet with slight smear of grease on them...
My advice is to buy a soccer moms car. Or non enthusiast who hasn't abused it.
