StkmltS Posted July 8, 2015 Author Share Posted July 8, 2015 I did a DIY smoke test but I think I want to pay for the real deal before I rip off my intake manifold based on my results. The high trim #'s are somewhat encouraging. It gives me hope that I may not have to start a build thread. My DiySB rebuild Got Misfires? Link to comment Share on other sites More sharing options...
MTBwrench Posted July 8, 2015 Share Posted July 8, 2015 It could be an O2 sensor as well. Have you replaced that yet?

xt2005bonbon Posted July 8, 2015 Share Posted July 8, 2015 Does the car idle rough and wants to die? Also, watch your oil consumption just in case. Link to comment Share on other sites More sharing options...

StkmltS Posted July 9, 2015 Author Share Posted July 9, 2015 i think he mentioned like a quart every 1300 miles It consumes basically no oil. I'll go back and correct post #1. At first I though it was using a quart every 1500 miles because about 1500 miles post-purchase I added a quart. Since then I haven't had to add a drop. Even after losing a small amount of oil during my valve adjustment the overall level stayed at the high. My DiySB rebuild Got Misfires? Link to comment Share on other sites More sharing options...

xt2005bonbon Posted July 9, 2015 Share Posted July 9, 2015 (edited) I see. Then I would recheck the usual suspects once again (plug, coil, inj). If all clear, then redo leakdown/compression. And maybe borescope. On a 'sad' note, I have noticed a few guys over here who did have cracked ringland and still were not consuming significant amount of oil...

Cracked ringland on 4, and it consumed maybe 3/4 quart every 2000 miles, and that's including the PCV and oil cooler leaks I had.

Diamonddice6 Posted July 10, 2015 Share Posted July 10, 2015 I swapped the wires, the car didn't turn on, I tried twice and read the codes, no change p0303 and p0304, discovered an oil leak under the car not sure from the where that oil is dripping but it is around the oil filter towerds tires...otherwise the engine bay from up iis clean....

StkmltS Posted July 19, 2015 Author Share Posted July 19, 2015 (edited) My clinder #2. The 90° attachment for my new borescope doesn't work well enough to see the cylinder wall. Despite that the camera is still easily worth the $20. It works great with my OTG cable on the two android devices i tried, and the free CameraFi app is excellent.

StkmltS Posted July 24, 2015 Author Share Posted July 24, 2015 (edited) Any thoughts about the appearance of my cylinder #2? I drove the car about 630 miles since Monday (trip to Pittsburgh) and about 100 miles into the trip the car developed a loud boost leak. If you listen very closely you can hear it hissing at >0 psi, and anything over 5 psi makes a super loud "pssssweeeee" sound. I just stayed out of boost the whole time and hoped nothing popped (it didn't). I didn't get one single CEL the whole trip, which was very surprising and fortunate because I forgot to bring my bluetooth OBD adapter and my OTG adapter. 600+ miles without cruise control would have sucked. I haven't found the leak yet but I'm pretty excited because it's another potential fix that's less time/money than #Inansb. I know I'm grasping at straws, but a guy's gotta have dreams. Here's my fun LV from this morning. Edited July 24, 2015 by StkmltS My DiySB rebuild Got Misfires? Link to comment Share on other sites More sharing options...
heiche Posted July 24, 2015 Share Posted July 24, 2015 wow, your missing cylinder came back? awesome news! did you do anything else to it, or did it just come back? I'll bet your valve clearance adjustment did it, maybe it didn't come back right away because there was a little carbon buildup between the valve and seat, and it got hammered away eventually? looks like (and sounds like) now you just have a classic post-turbo boost leak. the lean low load cells, and the rich high load cell, and the whistling noise all point to that. are you running the stock tmic? maybe it's separating at the end tank (is the tmic oily near the turbo outlet?). Or perhaps the throttle body hose isn't sealing? BtSsm - Android app/Bluetooth adapter. LV, logging, gauges and more.

xt2005bonbon Posted July 24, 2015 Share Posted July 24, 2015 Yeah, do check the throttle body hose. It is notorious to come apart after a while. See here http://legacygt.com/forums/showthread.php/pegged-negative-af-learning-all-ranges-no-knock-iam-1-225843.html Although I would note that when it happened to me, all values were getting negative, probably because the leak was very obvious in my case.

Or perhaps the throttle body hose isn't sealing? I don't think it came back [fixed] because you can still hear and feel it misfiring. I guess the valve job and several hundred miles of steady highway driving was enough to clean things up a bit and keep the CEL from coming on. My misfire and low idle problems are still very much present. Yes I have the stock TMIC. Yeah, do check the throttle body hose. It is notorious to come apart after a while.

Bummer, it was only a lose hose clamp on the throttle body hose. Maybe I didn't tighten it all the way when I put thinks back together after adjusting my valves. Back to the drawing board. Despite the motor issues I've been dealing with I must admit... after a wash, clay bar, and wax, it's a treat having a 10-year old car that looks this good. My DiySB rebuild Got Misfires?
