Hot Dip Block
Wondering if anyone has hot dipped a 944 block. I want to clean my new block up but dont want to damage the cylinder walls at all. Is hot dipping recommended or should I just use good old elbow grease?

Hot soapy water (use ivory liquid) and use a blow gun to dry out the passages.

I used a pressure washer, paint brushes, tooth brushes and several other tools and a good degreaser. let it soak for a while. Blow out all of the oil passages

Took it to the car wash and pressure washed it.
Similar procedure to davids..... As long as you blow it out well.............

Yea if you hot tank your block in the same chemical used for regular cast iron blocks, you won't have a block left. The acid will eat the aluminum to nothing. There are chemicals(acids) that are fine for aluminum, usually referred to as cold tanks, but something as large as a block i'd avoid it.
Most good machine shops have a hot bath. It's a machine that you place parts on a vertical rotissery. Door is closed and the part(s) are pressure washed in a mild chemical degreaser solution, but at ~300 degrees F to dissolve any oil/grease residues. Remove and rinse/blowdry and you're left with a very clean part. Usually only used on heads and aluminum parts, or stuff too fragile for harsh chemicals....but most are more than large enough to accomodate a 944 block. Mine's big enough to fit a 928 block in it.

Pressure washer and soap per Porsche recommendation for mine. Not sure what that procedure would do. I didn't want to run the risk of damaging my motor.

I haven't done it with a porsche block, but my MO is to go to a car wash that has the degreaser option. Bring a few cans of Foamy engine Brite, a couple of stiff nylon brushes, old towels, a milk crate, and some WD40. Wear grungy clothes, this gets messy. Spray and scrub the block on the crate using the engine brite. Drop in a few quarters and Pressure it all down. Dry with an old towel and/ or leave it in the sun for a while. Spray the WD40 on any exposed metal you don't want to rust right away.
It is also a good idea to scrub off an engine before you do major work. It helps you see what you are doing and minimizes mess.
