Do I need help? The only engine I have cleaned before was on my 88 fiat uno turbo at least that had an alloy head.
I didn't realise that the 'engine' in my 330ci is really just a series of plastic covers, haven't a clue what the real engine looks like. Shame really.
Anyhow cleaned what there was and man it looks good now
Used autoquim engine cleaner to degrease and a silicone spray to 'shine' up.
