HELP - Smoke coming from dipstick tube + egr cooler after EGR and manifold clean

Hey all! So i had taken my EGR valve and inlet manifold for a good cleaning, put everything back to gether as it should be and car started fine, but when i rev it i can see some smoke coming from the dipstick tube and also the area where the EGR cooler is (BRD Engine code)

Have i damaged my engine? Or is this normal? I haven't driven it and i shut the engine down straight away to prevent any damage

Ran diagnostics, no fault codes..

Please help!

Smoke from the dipstick tube when removed is normal and the smoke on the EGR cooler could just be grease burning off.
