I asked my brother's friend who's training to be a GM Tech if he knew how to clean injectors. He was like sure, just get some Top End Engine cleaner part #1050002 and let the tips sit in it for a while, put some in the fuel rail, and check them with the ohm meter.
Sorry Rich from Cruizin Performance, but this sure beats like $90 to send them there, since I have an ohm meter and that can is like $7 a can. Is this gonna do the same thing as far as cleaning goes or is there something else involved?

P.S. gotta check because this guy has given me some faulty information before...told me there was no such thing as a 572 BBC...

 

Rich takes them apart, cleans them thru some ultra sound process, back washes them, flow test them, checks them 2-3 ways with ohm meter. Installs new screens, and new orings. Also replaces the tip if needed.

Yea, this hope job may work, but rich's way sounds better. I just wish I had money to send them in.

 

Rich has a page up about what he does, with pictures... your friend's idea might work, I guess for $7 it can't hurt, unless he somehow shorts out an injector while doing it. Website is here: http://www.cruzinperformance.com/injsteps.html

 

Rich's process definately sounds better and I emailed him a few days ago when I first found out about it, but I've gotten no reply as of yet...so does anybody know how long the turn around time is usually?

 

I had emailed Rich a week or so ago regarding the Multec's I picked up from a junkyard... took him a few days for him to get back to me; he apologized and said his father was in the hospital. Hopefully nothing bad's happened since them. Oh yah, he told me that most Multecs have a high failure rate, and recommended I try to dig up a set of the Bosch injectors from a junkyard instead. 'Course, I'm only finding high mileage v6's... bummer.

And all the Gen II MPFI v6's use the Multec's, too... even the 2.8's. I thought they would've used the Bosch ones. Sucks, because I found a car one-high on a pile of cars with only 85,000 miles on it- and it had a 6 digit odometer so I knew it didn't pass 100,000. I was able to climb up on the car below's bumper, but they were Multec's... had to pass 'em up.

I get the feeling I'm going to be wasting the cash on brand new injectors unless I get lucky really soon. The leaking injector I have is driving me nuts!!

 

he emailed me back and said that it was about 10 days right now, so i asked him to put me on his "call back" list.

Are you saying then that it isn't really worth sending my injectors in then since they are multecs?
Is there anyway to tell what kind they are because I have a set from a 89 2.8 (pretty sure they are multecs then) and a set from a rebuilt 85 2.8. I would assume that they would be a replacement one since it was rebuilt, but is there anyway to tell.


P.S I have an extra set of injectors..the multec ones..if anybody needs some cheap.

 

I have dealt with Cruzin a few tines.. and 10 bucks an injector ain't bad. especially for what he does.

 

Damien, if they're all from f-bodies, 85-89 used Bosch injectors. You're sure they're all multec's?

 

I'm a little confused now...
So I assumed that the 89 injector were Multec's
the injectors from the 85 are either the stock ones or some replacement that was put in there during the rebuild.

How can I tell what injectors I actually have.

 

Multec's are the one's that don't have pintle caps? There just flat on the bottom?

 

Right.

MSD's injectors are the Multec style: http://www.msdignition.com/fuel_4.htm

Accel's injectors are the Bosch style: http://store.summitracing.com/partde...57#largerimage

 

well...mine look like the bosch style, so thats good.

now... I'm putting a cloyes roller timing chain, powermax 2030, and 1.52 roller rockers in my engine...will I need injectors that have more flow or will the ones that I have be good enough?

 

nobody knows if I will need bigger injectors?
