The car is reasonably clean inside , but no new parts under hood (except new shitty ignition coil that swelled to he point the boot stuck on the plug)
It has been lowered, with orange springs, previously replaced front struts (useless to me because of old upper strut-mounts)

TB drive cover removed

TB drive

Ready to practice

Took apart throttle body drive part, found thin layer of powdered rust under cover and all over the TP sensor
The car had really clean inside of the engine, zero sludge!
