Moving away from the engine removal and rebuild, strip and clean for the moment. I want to assess other aspects while the engine is getting the work over. In the meantime I am looking into other aspects of necessary/preventative work, along with other nice to have modifications. I am sure the list will get longer as we get deeper into the build.
When I received the vehicle from my brother, the four green lights in the instrument panel that look like wheels were flashing. I asked my brother what that meant and he told me it was normal. If I knew then what I do now, and he was a salesman that sold me the vehicle, he would have a damaged ear drum and skewed nose today. LOL. Yes after reading the wonderful links and information on this forum I came across the article on how to fix this issue. With the engine out, access to the vacuum actuators and switches is an opportune time to sort this one out.
I also want to redo the suspension. Not springs or torsion bars, just bushes and rubbers. The ball joints will also be assessed as will the tie rod ends etc. Shocks will also be replaced due to the failed bushes indicated previously. Looking for pointers on options in all these areas.
The 50mm lift article I found here also looks cool. I do not envisage dropping a few grand on tyres and rims just yet as the ones currently on the vehicle look OK for a few 1000 km's. Maybe!!

. Not sure the vehicle has not already had a body lift previously.
Bushes currently between body and chassis.
Tyre's currently on the vehicle.. This pic is of the rear tyre. Note the body height. Tyre size is M+T 31X10.50R15LT.
These are pix of the front and rear tyre treads respectively.
I have not looked into the 4X4 system as yet. (diff, transfers etc). All seemed to work when I took over the vehicle.
I am also wondering if I should just remove the body off the chassis and get the complete under part sorted. Anybody done that at home before? and was it worth the effort?
Any idea what this is? Note the air valve thing with a cap at the very bottom of the pix. The guys that put the vehicle through COR said that there was some sort of system installed for raising ride height when towing, and was faulty. Is it worth fixing this system or should i remove it? What does it actual do?
