That's how I tested my TMIC/Ypipe for leaks, and then everything post turbo. I found that hooking up a tester pre turbo is a PITA. Things that shouldn't see pressure do, you need to block off a lot of stuff, you can't see the Y-pipe, etc. I found several leaks using that setup.

Thanks Mechie. I had seen that before, because I'm an e-stalker...... I thought it would be helpful. Where did you pick up the bolt in stems? Local Auto parts store?

I didn't get a chance to take it out last night. Tonight I will.

My dad actually bought those stems for me 7 years ago when I was a college freshman making a potato cannon. I think you can just get them at an auto parts store. They weren't anything special.

Well it appears I had more than a few problems. I guess that can be expected.

I went for a drive last night with the factory intercooler and it appears it was absent of the noise. I'm suspecting the BOV flange area so I reinstalled the APS unit last night and used RTV instead of the factory style gasket I had on there.

Issue one:
Some serious tire clearence issues. I corrected temporarily with spacers I had. I think the long term is to get shorter springs as I'm not interested in making the car any wider than absolutely necassary.


Issue two:
Weird brake fade soft pedal issue. When I went for a drive the left front started making noise so I pulled it apart and found.


Hmmm active, varying, pad thickness. That could cause the pedal to act funky. Luckily I had some hawk pads on the shelf. I prefer the bobcats, I'll have to order another set. This could also be the cause of what Billy and I was feeling at natioanls.

Went out for a drive brakes are solid and once again I can put the car on it's nose if I choose too.

So tonight I hope that what appears to be a boost leak is gone. Crossing fingers on the BOV.

Tomorrow I'm going to drive to the subbie dealer and have the service manager pull the ABS codes. He states that there's a potential that I'll have to change the tone rings/sensors. IDK the rear tones are the same part # 2002-2007. The rear sensors are the same part # 2002-2007. It appears the front sensors a different part # each succesive year after 2005. I have some 2007 sensors so maybe I'll change the fronts and see if that clears it out.

The only part I'm unsure of is the front tone rings. Being that they are part of the axle assembly, if you look them up you're bound to get a different part # because of the internal/external axle change.

I did move the tune to 9:00 a.m. April 3rd so woot for that. The season is quickly approaching and I want the car solid before then so I only have to focus on suspension/alignment/driving.

Cheers, thanks for reading
Greg

OOOOOOoooooo, Hoosiers went on a slight weight reduction program I see! I wondered how those were not rubbing. Hope there wasn't any damage to the sidewalls.


and for the sake of humor........how many times did you bleed the brakes?



Glad to see you are getting everything sorted out.

Yeah, yeah, yeah. How was I to know the inner left front pad was non-existent. I don't technically need abs, but I do like it, especially in the rain.

No real damage to the tires thankfully, just slightly lighter.

I think it's because I checked clearence and then changed camber w/out checking again.

Come on. You know I'm not that bright.

I'm beginning to stress. I guess I need to keep it in perspective.
1. I've literally dis-assembled/reassembled the car.
2. Some people that started projects in the fall are still working on shells and will miss part of the season.

I was specifically looking for tiresmoke too......how odd is that? I'm glad that the other noise was a faulty seal. That saves time in digging for the cause!!!! Ya think those pads were borked prior to our little test drive? Guess they needed replacing anywho..... Get the ABS codes sorted and the big IC sealed up! Not sure what to tell ya about the wheels. You can try to pull the hub out at the bottom of the strut and slide the plates back in....but it didn't look like you have too much room up top.

This is all progress.....fairly smooth progress at that. Just think that I spun a bearing at a T&T 2 weeks before nationals last year......your pace is going just fine!

Well it appears the boost leak was nothing more than the factory gasket acting like a reed in a flute, on the crappy casting of the APS top mount.

I know you like that description. I can say these things because I've been around musicians.

Up next.
Change front wheel speed sensors.
Order (4) 6" springs and (4) 7" spring sets

Actually I know a local who has some so I'm gonna see what he has available first.

Jay, I definetly think the pad was borked prior to our test drive. I actually think the piece shifted as I stepped on the brake leaving the driveway, which is why I was thought. "well that was weird"

I am really-really happy to know that the noise was the gasket singing in boost......No more gaskets from Jethro Tull....... a'ight???

You'll make the first event, and I might have to come out and join y'all!!!

No real updates. Still chasing the abs thing, but got some good advice in the conversions forum.

I did however uncat my Cobb DP last night, that was fun.
Not optimal I know but I'm not buying another one.

I also installed stiffer springs. 600 fr 700 rr, so we'll see about that. I still need to order some shorter ones, however, to correct the front track.

So on the horizon. There's a TNT in Peru, IN. at Grissom the 24 & 25th hosted by Detroit. Our season opener is the 26th. and then the following weekend is the pro-solo in Lincoln.

I'm really looking forward to the TNT. I'll actually be able to see what the new TQ, diffs, and r-comps are all about. I'm sure it will be a completely different car.

I'll probably have to get used to this when the car works.

6 or 7 ". There's a local with some I've just been too lazy to go see what rates he has.

Are you heading out to the Pro in Lincoln? I'm curious to know what you think of the surface compared to Toledo. I can't make the drive out to Lincoln, so I'm trying to use Toledo as my measuring stick.

I'm sure you'll have that little buggy worked out and fast as hell in no time.

That's the plan right now. I can tell you by description alone Lincoln sounds exactly like Toledo.

Low grip, high tire wear, void of dips/elevation changes.

Should be fun.

I can also tell you my car never, ever, ever..........ever, rotated at Toledo, in stx trim. For as fast (slippery) as my car was/is, last year at the pro I was seriously comteplating running + camber in the rear just so it would turn.

That one aspect is something I will work on with each Toledo local we have. Getting a fat, transition challenged car to turn well on concrete.

You're welcome to mine if they can help you out. They're sitting in a box, destined for the DSP car, should it ever compete again......

So a bit of a run down.

ABS issue: it appears that I may have been sent an abs motor for an auto. There is one latent code that will not clear (47) improper can communication. The manual procedure says I either have a dccd or a tcm and to start there. I have neither. So I'll do a bit of digging and I'm sure I'll end up swapping out the motor.

The tune: It went alright but what it did flush out is that I have an underlying mechanical issue with the car. Could be a damaged sensor/s, could be the air pump delete, IDK.

Basically, it seems, when the car gets to a certain temperature it will begin to hunt for idle, sometimes stall, and then when you restart it it's pig rich and stumbling all over. It will always restart and if you let it cool down it will be fine until you drive it, warm it up, again. This happens on any map you throw in it.

IDK I'm kinda stumped, pissed at the moment. It could be one thing or a few things in conjunction. I'll start by grounding out the air pump connectors (even though I think that's a STi thing) It has been said that the lack of grounds from removing the air pump solenoids can cause the ecu to flake out.

But that's a cheap item to do and I'll do it before I move on to buying $300.00 worth of engine sensors. Some have said that engines from damaged vehicles can have sensor problems, I guess I won't discount it.

Could also be a ground issue I suppose.

Well that's where I'm at 2 weeks or so to the first event and I'm still knocking out gremlins.

I also need to do some data logging as that would probably show more than anything if I can replicate the condition.

You didn't expect it to be that easy did you?

Good luck getting those gremlins sorted out. No fun having your car *almost* there with the season getting ready to start.

Yes, I did. I may have stumbled on to something. I posted this in our local thread.

My idle/potential sensor issue. I was trying to logically go through what I've done, swapped, touched, etc. In an effort to eliminate potential culprits. As we know I've touched just about everything on the car, some more intimately than others.

I remembered when both my engine where on engine stands I swapped front o2 sensors. Logic being I had just bought the one in the 2.0 and didn't want to let it go.

Well in cruising around part #'s earlier I realized that 2.5's and 2.0's are different o2 sensors or at least by part number appear to be.

The issue has some ties to a suspect o2 but I didn't because it's brand new. Not thinking it's the wrong part. Car warms up comes out of CL starts reading the front o2 for it's calculation and bingo bango freaks out. <- that may not be entirely accurate but you get the point.

Thoughts?

Well between changing the front o2 sensor, the crank position sensor, and cleaning the maf. It seems the idle hunt and bucking between shifts is gone.

I would like to think it was one of the (2) sensors that corrected it but in all reality I probably spent a couple hundred bucks to spray my 1 year old maf . IDK. It never hurts to have a spare o2 with you.

We went out and did some datalogging and a bit of road tuning last night. One of the main issues of the car running bad was it was throwing the afr's around. With that, apparently, gone I will be handing it back over to Pure Tuning to spend some more time with it on the dyno. I obviously want everything possible rung out of it.

I actually asked that it spin to 12,000,000 rpm's and reach full boost (800 psi) in neutral.

Now I can work on suspension, fender rolling, etc.

Was the MAF visibly dirty? Maybe too much oil in that K&N. Either way, glad you got it and hope the tune goes better this time!
