Yes had an industrial one. Used 44 gallons of tricholethane, and would clean things in seconds. We used it to clean PCB's, and that was a fine balancing act between stripping off flux residue, 2 seconds, and stripping off the conformal coating, ranged from 5 seconds to never, depending on the exact conformal coat used, of which there were 3. Leave a board in for 10 minutes and the resin bonding the actual fibreglass weave together left, which was useful for some boards, where we were robbing parts off them, and did not care for the actual board itself, though it did a number on component markings, so they were all labelled again afterwards to identify.. Hot solvent was also great to remove potting compound from the high voltage assemblies, it took around 1 minute cycle to soften the surface, and then you could pick out the soft resin without damage. When finished pot the assembly again to keep it from arcing over.
Friend would bring stuff over for cleaning, though I told him when to bring dirty things, like carburettors, valve assemblies and such, when it was getting time to replace the fluid due to it being too dirty. Then all those went through in an hour, and then dump the hot dirty fluid into a drum for disposal, and fill with clean new fluid. Carburettor, put in black with dirt, and it comes out looking like it just came out of the casting mould.

Blaster is also very good at cleaning EGR tubes, as it simply has to have the suction attached at one end, probably using some duct tape, and then blast from the other side, so you do not waste the media, and get it Noisse and Shiny as Ray wants.
To blank off parts that do not need it best to use duck tape, and it will hold up well to the media, unlike painters tape. For the media valve simply get a large diameter water valve, exactly like the air line one, and put it a little further down, and use it to turn off the walnut flow. Large diameter valve, also called full bore, so that it does not clog, and probably best to use a ball type over any other as those at least do not clog up easily, while others like butterfly will, and the only one that will work with mud and muck is a pinch type, which closes off the hose by compressing it.

US engines are typically much higher power output, so the oil is run harder. Note this is a 3.3 l engine, when the corresponding model in the EU area would be a 2.0l engine, in the same block. so the US engine has higher power output compared to the EU block ,and also has much more severe operating conditions, because of long distances traveled every day, and because of this and lots of short drives, because in the USA you drive to the local stores, while the rest of the world you either walk 3 minutes, or have a once a week shop habit. Remember in the USA you often have people commuting 4 hours a day, often in stop start traffic, as there is little to no public transit, and thus a vehicle has a cold start, then run foot flat for 2 hours, then from that to off and cool, down, and repeat. Much more aggressive drive style as well, almost binary in pedal position, either foot flat, or hard on the brake, because there is no defensive driving taught, or any sort of care for fuel economy, because USA fuel is cheap. Leads to fuel dilution, high engine loads, and also because of higher internal stress early failures
By me that same Sedona comes with a 2.0l 4 cylinder engine, as there are not many V6 and V8 engines, and also most vehicles have lower power ratings compared to the US model. Yes much lower power, but they then again also last a lot longer as well.

That bushing looks like it was made from polyurethane. Cheap urethane will disintegrate with time alone. Had one that went, and, rather than replace it with the same junky urethane, I decided instead to make a new one out of some scrap rubber belting. 3 small strips, held together with 3 small nails used as rivets, and it was a "never bother with you again" fix.
Did later have to replace the motor, it decided to burn out, running around 6 hours a day, after another year of abuse. But I had a spare motor, only lightly used, from having to replace the previous pump because of that exact coupling failing. So put it in, same coupling half, with the same rubber coupler, and it ran till the machine was sold off. Coupler used to keep the pump from having axial thrust, because a vane pump has bugger all tolerance of end float, and will eat up an end of the rotor and the end plate. Less than a thou of clearance is the difference between work and does not grind into mush, and not pump at all, with the oil film providing the seal. Yes those pumps did not live a merry life.

Military with drums of fuel always left around 30l at the bottom, because of the chance of water contamination. So those drums always came back to depot, where they got properly emptied, and then refilled. Friend was doing that run one week, and found out he could not fill the truck at the depot, refused as the bill was unpaid. So took down a drum with the crane, and emptied all that ullage from other drums till it was full, and lifted it back up till it was back in position, above the fuel cap. Then hose into it, and siphon onto the tar till it was running jet fuel, then filled the tank. Hose was the depot watering hose, not fuel rated. But that truck ran very well on the jet fuel, lots more power and pep, before you rowed the box at any incline, now it did not need any gear changes at all, and easily kept to the speed limit.

I have set timing by ear, then checked later on with a timing light, and it was pretty close, so it never got adjusted, as it was close enough to correct, and within the timing error. New distributor, or rather new to me, because the original distributor got stolen in the street. Toyota engine, and that is a very expensive distributor, and was also only available as parts, and half out of stock. New was close to $400, used one, from a rolled vehicle, was only $25, and came complete with the plug leads, clamp, vacuum lines and the bolt.

Or just contaminated gun, because the shop does not pay for 3 rinses in the gun before you change paint. Dump out the little bit of left over, wipe with a not solid yet rag, then a rinse with a tablespoon or two of solvent, then the next one goes in. Yes might be bubbles because the clearcoat ran out, but also probably old flakes of other paint that peeled off finally. Also a rant about body shops, modern paints can go on and be gloss straight off, why does every paint shop put it on to a matt finish, then buff the hell out of it. First time I ever used a spray gun with epoxy based paints I only had a slight matt finish on the first coat of primer, and the second coat was dull, because i used a fast thinner on it. Then the main coat i used a retarding thinner for all 2 coats, so that I would not have that. Yes did have a little bit of fisheye to fix, because I was learning just how bad silicone can contaminate, but that was doable with sanding down, and a redo a week later on after it had cured. Then we did a friend's car, where we got both coats done using only 1l of paint, and 2l of retard thinner, we just made it to the end before running completely out of paint. Had a few dust spots, but no booth either, just Saturday afternoon and Sunday morning, under cover as best as possible.
