Hi Nell - you could try soaking the tar with white spirit - may take while though - I have seen diesel used but you need to be careful and be patient. I my view the tar remover stuff you talk about evapotates too quickly. I would be wary of having the engine steam cleaned as I have seen and heard of some horror stories regarding damaged electrics.
