Flow 1 Report post Posted October 9, 2013 Check this guy out! Salt of the earth and amazingly good value. I had to beg him to charge me $10 per injector including ultrasonic cleaning, replacing pintal caps, O-Rings and filters... He was only going to charge me $5!!! http://www.bimmerfest.com/forums/showpost.php?p=7883530&postcount=15 Quote Share this post Link to post Share on other sites
curryinahurry 38 Report post Posted October 9, 2013 Very interesting! How much did it cost for postage? Did you feel any performance / efficiency improvements after the clean? Quote Share this post Link to post Share on other sites

Flow 1 Report post Posted October 9, 2013 Hi Guys. I'm in NZ. The shipping both ways was about 70 so all up it was about 200NZ. To get the same job done here you'd be looking at $240 + GST + parts. I got these done as I thought I might as well considering I had to take them off to do all the other top end preventative maintenance I am doing at the moment. See http://bimmersport.co.nz/topic/45899-e39-540i-m62-vanos-seal-replacement/?p=502877 for more details. I won't be able to really say if this has improved things as I am doing my VANOS seals at the same time. It looks like my #6 injector was a bit down on flow though. So I am glad I did it. All the best Jason Quote Share this post Link to post Share on other sites
jeffbebe 1559 Report post Posted October 9, 2013 I bought a pintle and o-ring kit on eBay for $20 and got six injectors cleaned and refurbished for my old 528i for $25 each at Edgell on the North Shore. My regular mechanic said he can do for the same price for my V8. About the same price and I won't have to wait for them to go to and from the US.

Etwenty1 45 Report post Posted October 9, 2013 I had some e30 ones cleaned at a deisel specialist. 4 for $80. They ran 2 cans of brake cleaner through them then tested the spray pattern. O rings were a DIY using circlip pliers ro remove/refit. Even though they looked dirty to me the guy said they were fine. I no longer get injectors cleaned.

thorburn 120 Report post Posted October 10, 2013 you got scammed. There is a huge difference between sending some degreaser(or brake cleaner through injectors) and ultrasonic cleaning while the injectors are being pulsed Quote Share this post Link to post Share on other sites

Flow 1 Report post Posted October 10, 2013 Hi guys. The shipping does take the icing off, even still I couldn't stomach letting him charge me $5/injector! I do believe he is doing ultrasonic cleaning as well. I will confirm that though. Cheers Jason Quote Share this post Link to post Share on other sites

Etwenty1 45 Report post Posted October 10, 2013 you got scammed. There is a huge difference between sending some degreaser(or brake cleaner through injectors) and ultrasonic cleaning while the injectors are being pulsed quite possibly, but they did what they said they would do. I put injector cleaning in the same urban myth/placebo effect category as auto sparkys suggesting HT leads should be routinely changed. Ive heard about untrasonic cleaning but never first hand from someone who said it improved their cars performance. Quote Share this post Link to post Share on other sites
Apex 693 Report post Posted October 10, 2013 How much are new BMW ones? I just replaced mine for the race car and it was bugger all more than what it costs to have them cleaned! Quote Share this post Link to post Share on other sites
jeffbebe 1559 Report post Posted October 10, 2013 How much are new BMW ones? I just replaced mine for the race car and it was bugger all more than what it costs to have them cleaned! Quite a big difference. As much as $140 each from the dealer in NZ. You can brand new online for around the $80 mark + shipping (which isn't much) but I highly recommend buying a pintle and o-ring kit at $20 and getting them ultrasonically cleaned. Made a big difference to my 528i, which was a 1996 so the injectors pretty clogged a waxy residue and the flow was less than perfect. Like any rubber seal in a car the o rings begin to perish at around 10 years old so well worth doing IMO. Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted October 12, 2013 Where I used to work a few years ago we had the eqiupment. To service injectors correctly requires putting them in the test machine - running a flush through them while checking/comparing spray patterns, flow rates, checking for leakdown. Then removing filter baskets, pintel caps & running in the ultrasonic bath. Replace filters, pintel caps & O rings, rerun through the test machine rechecking the above. Looking for even spray pattern & flow rates & obviously no leakdown. Using proper machine allows running a variable control pressure & firing time - meaning they can be checked under duress. And yes, we were charging $40 + GST per injector. Putting in perspective though - the machine cost/ fluid cost & labour spent on each service - the cost was reflective Quote Share this post Link to post Share on other sites
nath 128 Report post Posted October 12, 2013 (edited) Just got my 5 injectors done, exactly as above etc. Man the ultrasonic clean must be good work as you can see the angle they lay in the bath due to the paint stripped off! $172.50 incl GST Edited October 12, 2013 by nath Quote Share this post Link to post Share on other sites
Flow 1 Report post Posted October 22, 2013 Hi all Dimitry has confirmed that he does use an ultrasound bath as part of his process. He did say that you are better to replace an injector that is suspect rather than trying to resurrect it with ultra sound. He does not have a ultrasonic bath that allows him to pulse and flow the injectors at the same time. He said that pulsing them dry is a sure way to over heat and damage them so he doesn't pulse them in the bath. Out of curiosity does anyone have an ultrasonic bath that flows and pulses the injectors at the same time? Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted October 23, 2013 I always ran them in the ultrasonic bath with them connected to the flush machine to pulse them during the process. Before putting in the bath i removed the pintel caps & filter baskets & filled them with the caustic fluid from the top - keeping them "wet" while running. Never had an issue. Wish I still ahd access to it. Quote Share this post Link to post Share on other sites

Flow 1 Report post Posted October 24, 2013 I can't report on how it feels in the car just yet and I don't expect to as it looks like mine were all good except for #6 which was only slightly out and the clean bought back into spec. When I used to do this job in the trade I would often see a very noticeable difference in spray patterns before and after and saw many an injector stop leaking. We had an ultrasonic cleaner that pulsed and flowed at the same time. Quote Share this post Link to post Share on other sites
