Trying to re-seat injectors

Got apt with andrewtech Friday, hopefully they're the sh*t like i've heard

Are you driving it there or having it towed?

If you are driving it I would change the oil before I drove it. Why? If you have as much gas in your oil as you say you do I would be worried about wiping out your main bearings at this point.

But...hey...maybe I am paranoid.

oh...

and...

And the guys at Andrewtech are that good...stop screwing with it after they fix it.

Are you implying I am the problem with my car?

BryanH · Post by **BryanH** » Tue Nov 27, 2007 7:33 pm

According to Julian the car came off the last tune running GOOD. It seems to have gone downhill from there. You may not have liked/been comfortable with the power delivery but it ran well and made good power.

I have screwed up my own car before....are you trying to say you are incapable of it? Because if so that is an amazing statement.

Now maybe I am completely full of it and something has gone mechanically wrong...but it is certainly an odd timing of events.

If by running good, and I assume you meant running well, sure... except for dumping fuel in my oil and 12MPG off boost. The only fiddling I did with it was to re-seat my injectors, which did not result in any change to the car. I've been under constant advice from Julian AND Darrin both of which are stumped at this point. Please go back to trolling unless you have a useful contribution to the thread.

One is poking fun at you but the other isn't...please see a couple posts up.

Please change the oil before you drive it up there. It is cheap insurance if your oil is that Fubar. If you want I will even buy you the oil.

edit...

and it is partially funny to me (in a sick twisted sort of way) having been through a major warranty thing with Subaru lately where they went back and forth forever before they finally replaced the entire engine assembly. At least you are dealing with a competent aftermarket shop and not a corporate bureaucracy.

ok thanks

Darrin: I forgot I can't log w/ the WBo2 since that damn remflex DP gasket seems to have blown out. ( And I installed it w/ a friend, torque'd bolts as far
as they would go ) Good thing I have a spare set of metal gaskets.

Bryan is right, you should change the oil before going up there if you are driving it(chances are, if one of the injectors are dumping, you could be washing the cylinder walls - BAD THING) HOWEVER - I would highly recommend that you tow it... that way they see how much fuel is in the oil and you are not going to do any more harm.

I'd love to tow it, but not for $500. After all my upgrades and fixes and problems money is pretty tight. I will have the oil changed and ask for a sample and also check the dipstick before the change.

Andrewtech did not find anything really wrong with my car, other than the symptoms explained earlier. Did a compression test and passed @ 150PSI all around. I had em replace the spark plugs for shitz, the old ones aren't too bad though. Put the stock injectors back in, detuned my map and will log a bit to see if they get 12MPG off boost as well. If that seems to be the case ( stock work fine ) I will be ordering some Deatschwerks.

That is a bit of a mixed bag of good and bad news.
You should probably send those PE injectors somewhere to have them tested.

Initially from driving back it looks like my mileage has returned to what it should be, will continue to drive and log though.

Phibs · Post by **Phibs** » Sat Dec 01, 2007 2:51 pm

One thing I did just notice is that the gas guage would be say:

F
--

x

--
E

No low fuel light on. Then I'd turn the car off after driving. Turned it right back on and now the light is on and I see:

F
--

x
--
E

What would cause that?

Followup: Got 77 miles to this last 1/4 tank of gas, and when I filled her up
she took 14.3 gallons so prolly had a few more miles too

I still have an elevated oil level w/ some gasy smell but I also drove to AndrewTech with that oil and the PE850s so that could be where it came from.

Another question: AT removed my power steering line to do my injectors and when the car is cold now it makes the annoying power steering whine. Once it warms up seems better. Any ideas on how to fix/stop this?

BryanH · Post by **BryanH** » Sun Dec 02, 2007 6:53 pm

when was the last time you flushed your power steering system? And also have you checked the fluid level?

I know when they did my engine swap they sent me home with a bottle of fluid because it dropped quite a bit on the ride home as air worked its way out.

Never had mine flushed, @ 25K miles prolly about time anyway?

Ok now this is odd. On the last 1/4 tank I appeared to get 77 miles, on the first 1/4 after filling up, only about 45 miles. What's the deal ?

There are so many things that effect fuel consumption that there is probably no way to narrow down what the source is w/o some serious testing on your part.

1. It is now getting cold and your cold start and run fueling will be very, very rich until it reaches normal operating temps (and that will likely take 2-3 times longer as the temps stay near freezing).

2. You are now running winter gas which gets less mpg than summer gas.

3. To make sure your not just getting an anomolous event you will have to keep very close track of the gallons pumped, mileage, driving times, average driving speeds as well as the temps in which your running in. And you will likely need to do it for a couple of tank-fulls, ideally from the same gas station.

All that aside, a drop of 2-3 mpg during the winter time in not very shocking.

Still a decent amt of gas in Oil after an oil change and Injector install ( Deatsch 740 ). Still not making the right power. I'm at a loss here. If Andrewtech doesn't know what's wrong / can't fix it, wtf do I do?

The gas in the oil is troublesome. Do the Deatsch have the double o-rings on top like the others?

You've always made power. I don't know how many times I have to tell you that. The dyno charts don't lie. While it may not feel fast to you, you are making power (and lots of it!). If you don't believe me, let me drive your car (with you in it) and we'll go against another Stg 2 STI.

sell it to gabe, cut your losses, and buy a prius.

Another problem is that it is now "cold start season." Your car will be running really, really rich until it gets to optimal running temp, which will take significantly longer.

The FXT (with stock injectors) reaks of gas for at least 10-15 minutes after I start it in the mornings. I also checked it's oil this weekend and could smell the gas on the dipstick.

No offence, but did you actually think you were going to get some "new" power out of the injector swap? Your were making 360whp. That is an excellent mark on the 20G. Why would other "smaller" injectors suddenly make "more" power? Your wideband logs didn't indicate that you were ever "crazy rich," and none of your spark plugs, were fouled which would have indicated that extra fuel was pumping in during normal and full throttle running. The only other thought I had was that they were flowing fuel when the pump turned on, before ignition, but I have no clue how to test that.

Your also still not being scientific about this at all. Your essentially repeating the same experiment, with the same factors and expecting a different result. It's still you in your car, him in his, and using your butt dyno as measurement. It's a flawed experiment and you need to find a new way to get true "measurable" results. There is some software dyno software you could get and run it on both and see who makes more power. Or go to a dyno day and see what they both put down. Perhaps get a G-Tech performance meter and do a series of perfomance test with the same driver in each car and see where the numbers lay down.

Seriously brother, the gas thing is an issue that needed to be dealt with, and hopefully these injectors will be the solution (crosses fingers) but I don't think any of us can comment or give insight on something in which we have no first hand knowledge (we have no knowldge of your buddy's car) and all the evidence indicates your car is making serious power. The kind of power no stock turbo STi could ever make w/o some trickery (race gas, alky injection, nitrous, built motor, you get the idea).

I have mad fuel in oil after yesterday when andrew put in the 740s and changed my oil.
