Cheers for that. Petrol has been the way I've been going so far but I'm gonna hit it with a new brush and new petrol to get the excess off. The block itself isn't to bad but obviously where grease and grime sits and hasn't got anywhere to go its a bit worse off. A toothbrush was the way o want but is there an easier way to get the block cleaned with out spending loads of $$$ cause its really just a project for the next few months and something to strive towards so I want to do as much by myself but I guess the big jobs I'll have to send out. Cheers again.
