Vacuum leak check of the cooling system.
It's so cold that I couldn't get really low vacuum but enough for this testing.
Re-connected the battery the day before but even after straightening the GND cable, it already took set and looked like twisted before.
The more I looked at it, the more I hated it and also the way the aftermarket wires connected at the positive terminal.
Also, the GND cable cramp was already overtightened many times that the cramp itself was already damaged.
Even after using my nice Knipex plier-wrench that doesn't leave any markings, I didn't like these poor looking terminals so replaced them at the positive side.
New GND cable installed and no longer twisted like in 'S' shape….
Next time, probably best replacing that very rusty hyd pipe holder.....
As mentioned many times, if done properly, you should see small gap left when you tighten the GND cable cramp.
After leaving for about 1Hr, no changes in the vacuum reading so happy with the result and time to vacuum fill the Type 2 blue coolant.
Hand cranked the engine many times followed by short burst of starter cranking and then the proper continuous cranking to raise the oil pressure.
No press warning light and enough pressure raised so happy to install the spark plug and IG coil.
Applied silicone grease to prevent further rust especially at the rear bank ones.
After initial bleeding, quick 30sec fire up to shift the remaining air in the heater line.
Another bleeding followed by proper fire up.
I must adjust the base idle rpm, fluid level, etc and then take compression so still lots to do but already happy with the very smooth sound of engine.
Short break and start again tomorrow.
