spinn My heavy duty steam cleaner is not impressing me. Supposedly melts away grease with jets of steam, it does, not like they show.

The old pressure washer with solvent/soap works good. High pressure can be harsh.

Clarify the ""oil relief holes". The holes for the pin end or the squirt holes on the big end sides.

benson38 i have a 1953 8ba ford/merc flathead engine block that we got out of the woods and have had machined and magnafuxed and cleaned a little bit but i need too clean the rust out of the water jackets and oil gallies does any one have any suggestions on how to besides using pipe cleaners?

1952_Chevy_Panel We had our BBC jet washed and baked I believe, still had rust in the water jackets of course.

Any of you old timers heard about the vinegar trick? Drain the coolant, fill your radiator up with gallon of vinegar, the rest with water. Run the motor up to temperature, shut down and drain. Someone told me about it, but I've yet to try it. Anybody else hear about that?

BOBCRMAN@aol.com Due to EPA requirements. Most of the shops around here use a spray washer (like a big dish washer). The cleaner has to be compatible with aluminum and cast iron. Unfortunately what cleans rusty iron EATS aluminum.What cleans aluminum doesn't touch rust. Another problem is foaming of the detergent. Wrong combination and you have a LUCY show situation with soap bubbles. (been there). I personally use this system along with a bake and blast system. The bake/blast cleans all visable areas. But, is limited on some internal oil/coolant passages. Also you have to be VERY careful to get the spent blast media out of the casting. A few pieces left in an oil galley and instant bearing failure on startup. The blast media also tends to peen over the tops of lifter bores and exposed edges. These have to be chamfered ar reamed back to size.
The blocks look like fresh from the foundry tho.

Zimmo That is my dilemma on my Olds 455 - lots of rust. I did find some crazy stuff on the web about removing rust though...With a battery charger...

A real hot tank will dissolve the rust. Unfortunately, due to environmental requirements, most shops have stopped using real hot tanks and instead use steam cleaner tanks. This gets the crud off but doesn't touch the rust.

302 Z28 It's almost impossible to beat a hot tank cleaning job, but the solution in the tank has to be reasonably clean. Most if not all shops push it too far before they change it out or rejuvenate it. Short of hot tanking it, and depending on how sludged up it is you can do a fairly good job with oven cleaner, paint stripper and other solvents. Pull all oil galley plugs out and procure some brushes normally associated with gun cleaning to get into the oil galleys. After you have done all that then take it down to the local car wash and give it a good washing. DO NOT however take a heavily sludged up block right down to the car wash and commence to blow that cr@# all over the car wash. That will get you banned from the car wash quicker than a muddy 4 wheel drive will.

Best method for cleaning engine blocks.....

I have had engine blocks hot tanked, jet washed, baked and tumbled, but it seems like none of these methods are better than the other. What is the best way to have a engine block cleaned????
