OK thanks for your reply and input, Ctopher! I thought it would and do intend to get one soon and will keep everyone posted on results.

When parts are removed, I typically hose them down with brake cleaner to remove water, etc., and then treat them with Corrosion X (unless they are parts that I'm going to paint - no Corrosion X then).

Baz, a mix such as that would work very well on your crusty, dusty, musty and rusty calipers, Bro!
As always - thank you, RT! I have used vinegar before on hand tools and it does work fantastic. I really like the fact that with these ultrasonic cleaners you don't have to use any of those nasty petroleum based solvents and such. Much better for the environment plus whoever is doing to actual work!

OK back to my U-boat now.....

New question:

Has anyone used an ultrasonic cleaner on their fuel injectors? If so, did it work?

On MrInjector.US it says this:

Quote:
Your injectors are not disassembled, none of the internal hard parts are replaced, the injectors are ultrasonically cleaned and tested to assure their performance. The soft parts are then replaced.
I had a debate with my mechanic this afternoon about whether an injector can be cleaned or not. He showed me a device he uses that you attach an injector to with a tube that pulls from a container you put solvent in. There's a pressure pump and dial on it and he said it pushed the solvent through with very great force. He went on to say he's had terrible luck over many many years and many many attempts to get an injector clean enough to reuse. Said we have to buy new. I mentioned the ultrasonic cleaning and he said it wouldn't work because you need the injector open while the cleaning is taking place.

I'm not opposed to buying a set of new injectors but am wondering what the brain trust here thinks. TIA for any opinions!

I'm very surprised that Shaun @ Tru6 hasn't chimed in on this. I'd love to hear his opinion.

Good call, I will find out.

Missed this one - that was actually started by Shaun - and he has 7 posts in it, including the OP:

Want to make a pump for acid

FYI: there is a video in the very last post with the device my mechanic showed me today.

Baz, ultrasonic cleaning will not work with CIS injectors, even if you are able to hold the pintle open adequately (with copper wire after pulling the pintle into the open position with plyers) because of the tiny screen that is built into the injector body. Some people have had short term success back flushing them with acetone and brake cleaner, but typically, they start performing badly again after a short length of time. The only long term option is to buy new ones (and hope that the new ones are of good quality).

Ok thanks, RT. You know, my mechanic was quite adamant about this today during our conversation. He's funny sometimes - he rolled his eyes and said "You know how many times I've tried to do it over the years? And it's never worked!" It's not that I didn't beleive him - I just wanted a second opinion. Now I have it, thank you.

What about the Bosch injectors. Brand new questionable quality? So a good idea to bench test them before installing, right? I imagine on my U-boat we'll be testing them anyway as part of testing the whole CIS before installing.

PS - My mechanic's name is also Ivan.

Unfortunately, Bosch doesn't seem to have a problem putting their once good name on shiit parts they currently sell. I do not know for certain about their CIS injectors (but if Ivan the Bohemian Porsche PIMP says the quality sux, you can bet that's accurate ), but for example, they make/sell diesel engine glow plugs (a simple device, really), and those pieces of garbage fail within months of install (I found this out the hard way, and then retroactively read all about their high failure rates). And then of course we have their infamous coils - been crap for a couple decades and are still for sale (and still crap!).

i`d would say if you look for 911 part which are very important to the engine, look in the US of A for an old stock.That what i direct to most of my clients.....there are several old good 911 part suppliers on east and west coasts;-)cannot name them here..right?i had a saga with the Suchs clutch kit 3 years ago ..and when i got an fuel filter made in Israel (no politics ) i was surprised too..never mind big problem Porsche did manufacturing engine-main bearings in Romania ,several engine builders got burned here over the pond....so find good old stock is the best bet...not my stash i shipped in container to Europe in 2009 that is just for me;-)

Ivan
ps BAZ.. i wonder if your mechanic has the funny accent, like me???;-)

Does anyone know if the PSC 1000 has a strong odor. I quit using a petro cleaner in my washer because of the really strong smell and by the way it was very toxic, melted my cheap plastic gloves. Very good cleaner, very low flash point, more cause for concern. Surely there is a reasonable cleaner out there that is water based. My parts washer is from Eastwood very similar to the HF one. I believe they all now say the pump cannot be used for petro solvents. Replacement pumps are rather expensive considering the price of the washers.

Water based parts cleaners don't work very well. You need to heat the solution for best results and that jacks up your electric bill, plus you have to wait for it to come up to temp and they're exspensive.
Cheap parts cleaners need to have the pump replaced with something made for solvents like the little giant all metal parts cleaner pump about $130.
Ultrasonics work well on certain parts like carbs,valves et but won't remove oxidation from aluminum et.
Ultrasonic cleaners wear out after heavy, continuous use especially the $250 30l eBay Chinese units.
Best cleaner for car parts that I've found is vapor blasting quick, and leaves a new finish.

when I got my HF ultrasonic cleaner, had read of using 1/2 part water and 1/2 part simple green and then a good dose of vinegar. the vinegar helps with removing rust. but wont totally clean badly rusted parts. so with that mine did put off a bit of a bad smelling odor. keep the lid on....

yep bead blasting is the only way I go on such badly rusted, corroded calipers. and if also if coated in grease/oil, a dip in the cleaning tank first. if you have a blast cabinet you learn quickly how debris will clog the feed line. I have to dump and sift my blast material occasionally if I have been cleaning stuff where hunks come off.

PS I do not bead blast the pistons....
