Northstar rebuild: Will style (Page 52/119) cptsnoopy JUN 24, 08:55 PM Vids? Ok, given that you are under a severe time crunch we'll have to let it go this time... ALLTRBO JUN 24, 09:21 PM I just talked with him, he does have pics but he won't be able to get them up yet for the aforementioned reason. They will be eventually, though (hopefully before too long). I'm trying to convince him to make it over here (a few hours away) before he leaves, if he does I can probably record some quick video with my camcorder. If everyone helps pressure him into it, he may cave. cptsnoopy JUN 24, 09:35 PM quote Originally posted by ALLTRBO: I just talked with him, he does have pics but he won't be able to get them up yet for the aforementioned reason.

Maybe Cliff will move this thread to the Construction Zone if I put up more pics. My ideas for the accessory drive won't work. What looked like a slick belt routing when the engine was out of the car puts the tensioner in the perfect place to run into the battery tray with the engine in the car. So the idea I had is scratched... However, I do have another one, but that one will be much more time consuming to implement, as I have to make an idler pulley mount that picks up a half-dozen or so of the front cover bolts. So anyway, I'll put the accessory drive back the old way and let the car down tonight. Tomorrow I'll give it a final inspection, start it and break it in. ALLTRBO JUN 26, 09:41 PM It must be running, he hasn't posted here in two days. Will JUN 26, 09:43 PM FIRE IN THE HOLE!!! With a flick of my wrist, I bring my creation to life. It rumbles, grumbles, growls, *SNARLS* and calms to purr like a mountain lion. I prod it with my right foot and it jeers "I hunger! Where are the Mustangs?". I stab it with my right foot and it thunders across the valley "I FEAST! BRING ME A CORVETTE!". At least that's what it was like in my mind. The engine primed nicely and fired more or less without incident. I poured about 5 gallons of 112 octane into the tank, then filled it with 93. I couldn't get all the old gas out, so I wanted to dilute it as much as possible. The resultint mixture should be about 101 octane and should run an 11.5:1 engine just fine. Due to time constraints, I hadn't had the injectors cleaned or gotten new plug wires. I drove it around for a few minutes until the temp got up. The temp came up and settled in, but then gradually crept up. As I was coming back, the temp gauge fluctuated distinctly as I crested a hill; this means air in the system. Since I'd been very careful filling it, this told me I most likely had a leak. When I got back to the hizzouse and popped the decklid, the joint between the thermostat housing and the waterpump housing was gently misting coolant all over the left side of my engine bay. Grrr... That SonofaB@#$% is getting some F#@%ing Permatex or RTV next time it's apart. I'm not putting up with that crap anymore. That joint had leaked when I was filling the cooling system, so I took it apart and carefully reseated the o-ring when I put it back together. It stayed sealed when filling the system, but the increase in pressure from the initial heat cycle made it leak. Annoying, but could be worse. The engine didn't quite run right. It did have a miss. My amuptated Caddy instrument panel told me that the integrator was 143 for the front bank and 105 for the rear bank. My half-assed program for the Caddy computer locks the BLM's at 128, so all I had to work from were the integrator values. So the computer thinks that the front bank is lean and the rear bank is rich. I can believe the the front bank would be lean because I found a serious nick/gouge in the #8 plug wire... so that could be a misfire. The O2 sensor would register the extra oxygen as lean and the computer would add fuel. The rear bank registers rich. Basically the only thing that could cause this is running rich. I suspect that I may have an injector problem, since the injectors had been sitting a while and I did not have them cleaned/flowed. However, the most important aspect of the test drive was that the engine DID NOT SMOKE. On the most basic level, the build is a success. Even if nothing else about the engine is any better than stock, it is at least a viable engine to use in a car. While it did have a miss, it still ran on 7 cylinders and definitely had power that I hadn't felt in a long time. Acceleration to any speed I tried was still effortless... just not quite as brutal as it should have been. I am slightly concerned about fuel wash down in the missing cylinder, but total run time is probably 10-15 minutes at this point, so I don't think I could have done anything to it yet. Fixing the miss should just be a matter of tune-up issues, like plug wires and injector maintenance/replacement. Fixing the coolant spray should also be straightforward. Unfortunately, I have ZERO time to do any of that, so I'll have to leave instructions with my dad for him to do it. cptsnoopy JUN 27, 01:42 AM Congrats! Erik JUN 27, 02:38 AM I'll baby sit and break it in for ya Will while you're busy ..Trust me Will JUN 27, 08:52 AM My transmission also has the classic Getrag input shaft noise. I was idling in the driveway thinking "That can't possibly be valvetrain noise"... depress the clutch and it goes away. Hmph. mcaanda JUN 27, 12:54 PM
