Project Thread Fredriks GT build, GT-build, rustoration, making parts and nerding out. Options

I am starting this thread "in medias res" with the car as it is today.
Then I will post a confusing mix of past and present, showing the project updates and process. Promise to nerd out on the details. (IMG:style_emoticons/default/welder.gif) .

The GT oil system is of course a challenge.


These are 3 vital components that are really difficult to come by/expensive

Luckily this is old school technology and possible to reverse engineer and replicate. At least the thermostate and oil pressure relief valve. Casting the oil filter bracket is a bit trickier, and most of them are magnesium also..


Thermostate housing 3D-model


OPR-valve 3D model (cast part)


3D-model of opr-assembly


Plugs (is it called that..?) for sand casting (I have a guy who is going to do the metal casting).

Work in progress, very exciting

That's awesome!! Very cool. Did you oversize them to allow for casting shrinkage? In the past I've had a number of parts sand cast and have had to oversize between 1.5-3% for different magnesium and aluminum alloys.

They are called plugs. (IMG:style_emoticons/default/smile.gif)

Thank you for the feedback!
I have compensated 1,1% in the model + a layer of filler.
