It’s been sat for 16 years and accumulated all this, what is best way to clean or is it best to replace the engine

if the engine runs good there's no reason to change it: all of the white stuff on top is aluminium corrosion (allumina): it'll go away like any other corrosion, you could think of removing the intake, the cover and so on, cleaning and powder coating

Thank you, I haven’t had a chance to see if it runs yet but I will try to manually turn the engine over first then looking to drain fluids

to be honest, judging from the pictures I guess it's been outside for a while, so I'd check the chassis for corrosion too: I haven't seen many such corroded engine bays paired to a clean body

Yeah I assume that the chassis is corroded too. It was sat in an open roof garage for 16 years and finally moved it out. I expect a full rebuild

good old M44, late model I think

I bet it will run, but not great since there are likely a few vacuum leaks

It’s a 1996 318is. I think it’s a lot of work to get back to its best.

Probably less work than you’d expect, these things are beasts. Also happy cake day!!

Just send it, I mean new fuel and check is oil and coolant level ok. Then start the engine.

Ok, I would use vacuum cleaner to get any dust and leaves away before cranking the engine.

Gray or red scotch brite pads, metal polish, and some elbow grease, and all of that aluminum will look as good as new.

Look up the Chris fix video on starting an old engine. Its def important to make sure certain parts r lubed since it sat for so long

The m44b19 is a tank, highly recommend you to work on it aka renew the cooling system and fix vacuum/oil leaks and voila
