    I have my exhaust manifolds off right now (changing the gaskets out) and would like to clean the sides of the block up while im at it. Does block cleaner actually work? Ive never used it before and would like any tips. I mean how should I plug the exhaust holes up before I start cleaning? Do I just spray the block cleaner on, let it sit then spray it down with water? Is it even worth a try?

    Stuff rags in the exhaust ports and shoot the sides of the engine with easy off oven cleaner and let it sit for about 10 minutes then wash it off with a hose. Works great and not too expensive.

    I was at auto zone yesterday and saw some stuff on sale specifically for block cleaning. If I remember correctly it said "GUNK"

    just don't leave it on too long, it'll strip the paint off too. Made that mistake once or twice.

    general dollar-mean green cleaner, it's the best thing I've ever used on anything. I think it might be a cure for cancer:D

    How's it do for elbows? See "My Big Fat Greek Wedding" for clarification.:haha::haha:


    Gunk has that same can but in a gell form. Works better than the runny stuff on grease & tar. Has a Blue, not Orange, cap.

    Don't get oven cleaner on any aluminum parts or they will oxidize right quick!
