Re: Cleaning the engine, transmission and final drive
Hand cleaning may take longer but I think that the results are closer to the original finish and easier to maintain. But in the end, it is your motor and your decision to make.

Re: Cleaning the engine, transmission and final drive
I agree with you on the dangers of of the abrasive materials getting inside the engine. But I also figured if I did a perfect mock up of an assembled engine the risk would be no different than riding in mud and washing off with high pressure water. Preparation is key. The bare block was washed in a solvent tank and blown dry. I reasoned block off plates would work better to close off large open areas. Installed oil pan. Gray tape really holds up well in small openings. My air pressure for blasting was relatively low. Tried to use common sense while blasting. Vacuumed the case before and while removing plates and tape. Blew out oil passages with air. I found no evidence of contamination inside the engine block. I agree with you that anyone who goes this route to proceed with caution. Prep work is very very tedious, but I enjoy that part also. I have read that some have the cases vapor blasted with lots of time washing internal oil passages afterwards. That seemed like more of a risk to me. I truly enjoy learning and reading about how others have their own cleaning techniques. My method may work for some. Maybe more new idea's from my way.

Re: Cleaning the engine, transmission and final drive
Glass bead is a bit easier to flush out as it doesn't gum up like soda did however, I can't imagine what a bunch of beads floating in my oil would do if not removed, the soda would be bad enough.
Anyway, that is my tale and now, I use chemical cleaners only. Brook Reams is doing a R80ST renovation and documented his cleaning methods, They look amazingly good, but then they should as they require effort on his part to get there.

Re: Cleaning the engine, transmission and final drive: Simple Green BBQ Cleaner
You are right,, I also used this product to clean mold off of my garage door and backyard wood patio. I did an exterior brick wall. I recommend spraying and let it work for about 10 minutes - wall was in the shade so no concerns with sun induced drying.kirkpatrick3890 wrote: ↑Thu Oct 22, 2020 12:23 pmI have had great success cleaning alloy parts using
Simple Green Heavy Duty Barbecue & Grill Cleaner. It's in an aerosol can.
Don't let it sit for long, rinse it off with water, and use it on cool parts.
Start pressure washing from the bottom up as this allows the product to keep working on the mildew/grime. Having done this in the past with just the pressure washer, this was a night and day difference - cut the time in 1/2 easily.
