I recently purchased this 1988 3litre from sydney..........my son and I drove it back to melbourne and during
the drive realised that a lot of work had to be done.
the car was essentially all there and only had very minor rust (this was found when we stripped and removed the engine.)The rust is in a common place on most 75's  in the valance panel where the fresh air intake is.
I stripped back all the sealer and lee from EXTREME BODY REPAIRS cleaned and repaired the surface rust, luckily it was only surface
rust, left much longer and it would have been a very difficult job to repair.

As you can see in the photos I have removed all the ancillaries off the engine and generally cleaned the block.
I have put a kit in the detensioner (yes I am leaving it oil fed) and will put on a new waterpump.

I have also removed all the injectors and will have them cleaned and put the original 7.5mm (as apposed to the 5/16th) fuel hose so it will look the
same as factory (I hate those aftermarket fuel hose clamps!!!!!!!!!!!!)

The rear main seal was replaced while the engine was out
I have removed the airconditioner

engine out and ready to fix a few things
I have ordered nolothane intake runners from highperfomance as the original ones are well worn
ordered a new oil sender and oil warning sensor (these generally leak after a few years and can be misdiagnosed as a leaky rear main)

first pic shows rear main before replacement...............these are a real pain to remove!!!!!!!!!
second pic shows the rack...........I am considering making this a manual rack similar to greg gordons (highperformance) simply loop the supply and return lines and pack the rack with grease.

I've only ever seen another 75 with those cracks in the front chassis. Good work anyhow.

This might be the perfect opportunity to dress up the motor. Give the aluminium a good clean (high pressure water) and maybe get some bolts plated. It will really bring some life back to the engine bay

did some more work on the engine
plated some components and painted headers

The plating looks great! My PS 'cooling' pipes have surface corrosion; can't do the same as you without draining the messy PS fluid, so I'll just have to clean and paint mine instead.

A nice clean engine you have! What coating is on the manifolds?

new intake runners
as you can see I have used 7.5mm fuel hose which does not require those ugly
little clamps.
Intake runners from Greg Gordon in the States.
