It's Running, Kinda...

Ya man, I'm down at Amanda's we took a drive all up in the NE. Car drives great, real smooth. This joker in an R32 (wtf is with all them popping up lately?) hears my my bov and wants to race but I couldn't yet, so that's coo. I just turned off.
 
Well, drove it all lat night and it ran pretty good, this morning I took it to work, and it's still running lean as ****, but only when cold. Once my Temps get warm and my EGT's go over 1000*F it's golden. Gonne replace the primary O2 sensor and see if that makes a difference.
 
Um... At this point? To have something that runs consistently lol!

Had another look and I ble an O ring for my #2 injector. Replacing it in 10 mins and will let you all know.
 
Keep diagnosing. Lots of little stuff can go wrong when you're doing swaps and such.

What's your oil pressure like?
 
Okay guys, I have a bit of an update. So I fixed my injector O ring... Before I begin, I jsut wanna say that I expected to have a few "wrinkles" to iron out, so I'm not pissed about any of this - the joys of having a new engine! I digress...

Anyway, so got the injector fixed, then went to start the car, and it would start, but then go WAY lean and die after about 5 secs. so, I tried about 20 times to start it, each time it ran progressively longer, and finally on like the 20th try it stayed running, and once warmed up my AFR's were righti n the normal range. Drove al lthe way home, and not a single hitch. Car drove liek a dream. This confirms my suspiscion on the O2 sensor. I' mthinking the heater in it went bad, since it won't read accurately until it's hot, right? So, all those times me cranking it got it just warm enough to work properly, and of course when It's running (hot starts are fine btw) then the exhaust heat had it warm enough to keep it running good. So, I'm replacing the O2 sensor tonight.

My AWR pan was leaking liek a sive (see other thread) so I took that stupid s*** Cometic gasket outta there and RTV'd it last night. Keep in mind that the whole time it leaked (only 1 day) the oil level was FULL the whole time. I topped it up. So anyways, I looked in my pan and my pickup has been hitting the bottom, even though I had to press in the screen on it to get it to fit the pan with thw AWR spacer, so basically there was only like 1/16" of an inch that oil could come into the pickup tube, which would explain my hot idle oil press of 17psi. (10 psi per 1000 RPM is required, so I was still good, but that's WAY too low for me) so after I cleaned my pan up, I took the AWR spacer off of the pickup and measured, and without the spacer (and with the screen now fixed so it's like normal) the pickup is still only 1/4" inch of the bottom of the pan. Why AWR includes the spacer is beyond me. That pickup sits WAY too low in the pan. Even now, it will still be submurged completely for 1" BELOW the L mark on my dipstick. So basically, even if I have NO OIL on my dipstick (who the **** would run it that low) my pickup would still be submurged. So, tonight the O2 sensor goes in, and I'll fill it back up with oil and try things out.

On a side note, Dana built another great engine. I pulled the fuse and cranked it first for about 20 secs to build oil pressure, then put the fuse in and it started right up after 2 cranks. (Just like normal!) It smelled like s*** while all the oil burnt off the pistons, etc and everything got seated in, but even now after only 250Km (about 175 mi) it's already starting to smooth out. The oil was full of microscopic particulates, as it should be, but no massive chunks of anything, so life is good!
 
dam there is alot i need to learn i guess. cause it seems liek there were a couple little things you had to do to break in the new motor. and most of them i didnt understand. but its sweet you got it running. if i were you i would take a long road trip this weekend...break that b**** in lol

Hmm very interesting on the oil pickup. It didn't seem like it was hitting, but I am getting a leak from one of the welds http://www.khaosman.com/gallery/whygodwhy/DSC09695

Glad to hear your problems are going away fairly easily. How many miles/km are you putting on it before giving it some beans? :D

Gonna put on 500Km before I even think about going into boost, then after 1000Km's it's onto the dyno for tuning, then it's fair game.

Ya, my pan was leaking in almost the same fashion as that, only my welds on the other side were unbroken. Seems wierd with these damn pans...
 
nice. glad the motor is working out for ya. what kind of numbers are suspecting the motor will put out?

Actually, long road trips are the worst thing you can do to a new engine...

i told you there is alot i need to learn about new engines lol. but hopefully you get some decnet miles on it from now until next week
 
Okay guys, just changed my O2 sensor, and the problem is gone. Thanks for the suggestion Sandspeed!

The oil pan hasn't leaked (yet) either, so my RTV is holding it looks like.
 
hey no problem , I'm glad its fixed. How much boost is needed to put down 320whp with your turbo? Can't wait to see some dyno sheets, it seems like there are going to be a lot of 300+ horsepower msps soon....
