Technical Mk2 uno turbo engine

[Fiat uno turbo original]

Hi all I need some opinions on my engine . It's all good with not a single problem but I don't know if I should take engine out and paint engine bay and clean the whole engine ?? Here are sine pictures . Opinions please. The top metal big parts of the engine are good and so are the pistons and oil rings and all the metal parts inside .
