Injector cleaning, Witch Hunter, or ?

[Danglerb]

Anybody try anyplace other than Witch Hunter?

Seems like injector cleaning is big biz these days, some nationwide chain called ASNU, plus a bunch of small shops.

Witch Hunter looks like $22/inj for clean, test, new filters and orings, plus shipping and some additional to make matched sets.

Couple places on Ebay clean and test for $80 including shipping, but no parts replaced (bone head easy, but sometimes no so easy finding right parts for 928).

Why mess with a proven shop. Go Witchhunter or go home

In all seriousness, I've used them twice (928 and my late Turbo Eclipse) and have been very happy with my results. You've seen my before and after and the printout they include. Be my guest and experiment with others, for me, when my Expedition comes time, I'm sending all 8 to Witchhunter.

Marren in Conn. Did my 951 injectors. I got printouts before and after. Quick turn. Same price. I never dealt with the other guys but I couldn't have asked for more from Marren. They found 2 bad injectors and they also had the wrong pintle caps on them. I think that's what they called them) Anyhow they changed all the seals and caps in the cost of the plan. They also sold me 2 good used ones. All were with in 1% of each other when done. I had more torque with the right spray pattern. 6 of one I guess.

WH was showing a 6 day process time last I checked. I have 8 dirty looking injectors I found in a oil pan with a little oil and three or so sets of injectors I have pulled.

Long term plan I want to update to modern injectors and rails.

Short term I figure if its worth sending them out, its worth getting a matched set, which means getting a couple more from wherever I have them buried, or also pulling the set on the car now. If I need to pull the ones off the car a shorter turn around would be good, as its getting moved daily.

I found a place in San Bernardino, Calif, but so far WH seems smart.

You do know that WH will flow match your injectors, don't you?

Here's some before and after and printout

+928 on WitchHunter. Quick turnaround. They really know what they're doing.

FWIW Greg Brown recommends that we change our injectors every 15-20 years...

I have used Cruzin' Performance in the past and was very satisfied. Got all the printed performance data for each injector. All the filters were changed, all the injector bodies were refurbished, and new O rings were sent as well. Richard called and apologized for not being able to put the correct 928 sized O rings on the injectors because they were Ford injectors(and since they weren't meant for Porsche cars, he would have all kinds of liability issues). I asked if he would supply the correct O rings to me so I could put them on and he agreed to send them along. IIRC, they were slightly cheaper than WH, but the limiting factor for me was that WH was on vacation for 2 weeks when I was ready to send my injectors.

I would use Cruzin' Performance again

Matching doesn't change anything about your injectors, they clean and measure the flow, nothing more. To get a matched set you need EXTRA injectors to select from. I figure a minimum of two extra to remove the worst two, so send 10 to get 8 matched and two spares. I may just send 16 if I find another full set.

OTOH just cleaning got your set of 8 within a couple percent.

You didn't or couldn't remove the hold down clamp?

Didn't know they were supposed to come apart until I got them back. Was better I kept them on, as they made them look like new

Being from Oklahoma I have heard of many people taking their injectors to DeatschWerks and have heard great things from them. And due to them being local it will be where I take my injectors to get them cleaned. Heard many good things from everyone in the DSM scene several years ago. But I have also heard just as many good things about WitchHunter.

Interesting. Now read my "local" painting thread on my Euro.

I hear ya Leo, Google street view isn't too kind to the location either, but a local guy said they do good work, so I do plan to check them out later today.

Seems like everybody is using the same ASNU test and cleaning rig with some variation on the chemicals etc., so I am not opposed to giving a local guy business if they offer some advantages in time or cost to make it worthwhile trying them.

Just saying that "supporting the local economy" seems to never work in my favor and has always cost me more money. My last burn was getting my KTM dirtbike cylinder re-sleeved by a local business. He effed it up to where I had to give him money to my damaged property back and still ended up having to get another jug from eBay. Never again. I will only use recommended shops from now on.

This one in AZ is $12 each shipped, good feedback on ebay, but not a lot of it.

Does having them serviced qualify as "replaced"?

I had mine Carbon Cleaned, not cheap BTW, and its basically just running hot Techron full strength through the injectors. I am sure it does some good, but nothing like an hour in a good ultrasonic cleaner, plus replacement of the internal filter and orings is essential since a leaky oring is just as likely as a clog to be the trouble.

Oops, I see your question differently.

Nothing else except maybe the 930 used this high impedance barbed injector, so figure NEW still means made maybe 30 years ago. In use eventually the coil and other internal bits fail, but doesn't seem like that is slow deterioration, but sudden death, so as long as cleaning restores original function its a question of total service life vs DOA new units. New "maybe" has the edge, but only way to get a reliable matched set would be use for some moderate period of time followed by cleaning and testing.

That said, going to a modern four hole injector is better than any option with older single hole. Rail style fittings are safer than hoses.

Another shop a forum member has reported good results from.

Mr Injector - Home

Mr Injector / Bill Johnson
6280 N Government Way #4
Dalton Gardens, Idaho 83815

Any gas injector cleaned for $16 plus actual shipping, ala $5 for priority mail.

Danglerb send the extra injectors to Mr injector and see what you get back. I call it value when a vender goes the extra mile. When you get them back take the others out of the daily driver and send them when you feel like it. You wouldn't need them right away. There's a form online that you print and send with the injectors and you can even get him to pay pal after he is done.
