Hi
I am looking to purchase a used 80 series petrol/gas and have found one that has a perfect service record etc. However it has a slight knocking / tappet noise coming from the engine.
any ideas what this might be and $ if the engine was to need a rebuild.

Certainly have the valve clearances checked out Lost in the dust.

If your unable to do, it its worth a report from something like Vacc (in vic)

I have one friend who never could get gas sorted out on his 80 series
and had it removed as a result of gas caused valve problems.

Another thing for you to check which is a rust trap is, lay down on the ground stick your head under the vehicle just behind both the front wheels. You will see a bracket that runs from the front guard in towards the fire wall, its a bit hard to describe but there is a bit of a so called metal braket that is part of the fire wall (welded) with two threaded holes. You will see a little rubber grommet under neath this, PULL the rubber grommets out on bothe sides of the vehicle and make sure firstly no water runs out, secondly get a torch (hard to do) but shine it up in the hole and try and make sure no rust, (you will need like a pencil torch) If any water is present and rusty its already started to rust, put a container under it when you pull the grommets out so you can check the water and make sure its not a rusty colour, also pull the carpet back inside DIRECTLY behind these points and make sure no rust has started to come through. If you intend to buy the vehicle LEAVE the rubber grommets out. They some how allow water to get in but cant get out due to the grommets. By leaving the grommets out water WILL NOT leak into vehicle unless its rusted.....Bit of a mistake by Toyota in design.. I did have pictures and everything on my computer but my hard drive died and I lost everything unless some one else on here has it ?? LPG ?????? A few people I have spoken to (when I was looking) have all had head issues due to the LPG ?? I do know of one bloke personally who has a spare sitting on his shelf as he has done three heads within 350k and this is with regular tappet adjustments. He even had the harder valve stem seals put in and a lube kit fitted after the first time but has done nothing to stop the problem. In saying that I have seen numerous 80's running petrol/LPG surely they dont all have that problem ??? Very expensive to get repaired if they go........ Regards Steve

My xray vision says dont take the chance, buy a cheaper 4.5 with no gas and have it installed fresh..get the refund from the gov......it is common for the 4.5 to burn the heater hose on the back of the head, passenger side.especially if it runs gas...
