Re: New to this Section- First LS Swap
To the OP,
Im surprised you didn't delete the steam lines all together... since your goign for such a clean look. If I saw hot you had it I would have said something lol. But the steam line doesn't need to go back to the rad... That looks like Poo. I would drill and tap the top of the water pump as most due. I ran mine into my waterpump spacers so keep it short and clean. I think you will like it much better if you plumb it back into the water pump. Then just cap the rad. Or even cleaner is to just buy the caps on ebay (they are cheap) and bolt them on and forget about it. Lots of people do it and have no issues. Steam lines just prevent air in the cylinder heads (localized air super heated to steam will eat the aluminum like a torch) by keeping it full of coolant and purging constantly. This is prob an issue that GM reconized and designed for the .01% of the population was doing something crazy to introduce air into the system... or it made production easier by purging air fully the first time they bleed the system on the factory floor.
Car is looking good tho!

Re: New to this Section- First LS Swap
Damn, I can't get over how awesome your car looks. Very, very nice.
I don't blame you on the steam line. I didn't want to tap my water pump either. Ran it to a nipple fitting on the rad and was done with it.

OH NO, Time to pick up a good aftermarket driveshaft. I have a Lingefelter 3.5 inch shaft.

Re: New to this Section- First LS Swap
Yea, waiting to hear what the shop sais. Might just let them fix the exhaust and put a shaft in there, sick of messing with this... thought I was done lol. Either way a good driveshaft is going to be pricey. I really thought the 10 bolt would grenade before the DS, but obviously I was wrong.
Not real worried about the bag, I'm sure I can get a used one pretty cheap. Just hope the tunnel isn't fubared and it didn't mess up the extension housing on the trans or the rear end yoke.
He also said the MAF isn't coming in even though I know I had it in my scanner previously. He was putting a SD tune on it which I don't really want, so I'm gonna have to fix the MAF too I guess.

Re: New to this Section- First LS Swap
Wow that sucks, sorry to hear man. Doesnt surprise me though... look at how thin the stock DS is!
I personally use Denny's driveshafts. I get his steel nitrous ready DS for all my applications, a bit heavy (i dont like aluminum) but you can't break them... and if you do they replace it for free. ARound winter time they have a sale and I get mine for like $400 shipped all ready to do with a spicer yoke and 1350 spicer solid Ujoints. They are very nice and great people to work with. ALuminum will run you close to the same if not more and not be nearly as strong or have any of the fatigue life that steel has.
Get rid of the air bag... I hate them. too many crashes without an airbag and walked away with no face trama. The air bags destroy your face them they go off and you hit them.
Were you not running a DS safety loop? I would be running one for sure if I was you (i do). It could have been alot worse. Imagine if you were going down the road! You would for sure have holes in your floor pan.

Dennys looks great, only issue is a 4 week turn around. PST seems to come just about as highly recommended and they are running at 48 hours, and only a state away from me.
Most seem to have the same sentiments on the air bag, I have had one keep me from going through the windshield, so I dunno man. Going to put another in for the time being and figure it out later if I want to ditch it.
Loop, and upgraded DS were in the plans when I get funds for a 9". Figured this would get me by til then, but apparently not.

Re: New to this Section- First LS Swap
I have never had an airbag do anything more than cause more damage/injuries than they are "designed" to prevent. Hell, one of my roommates just jumped a curb in his older Accord and both airbags blew. Burned him up the arm, and shattered his windshield. Go figure.
I'm going to go Denny's myself once I have everything where I want it. That's also down the road for me, though. The SFC's I'm getting come with a built in DS loop, so I'll be good there.
I'm really hoping you don't have anything too extensively damaged, and it's all just a little hammering here and there.

I had wanted to do inner SFCs with a DS loop. That and some new sway bars and maybe weight jacks and I literally cannot change anything else on the suspension. Might go ahead and grab the Spohn unit, need to do some research and figure out what is going to work with what is on the car right now, exhaust etc...
Shop still hadn't given me an estimate and I was getting separation anxiety so I went and picked it up last night. Damage wasn't any worse than what I already expected thankfully.
Interior is fine, it blow the ash tray in the back.
Tunnel isn't too thrashed. I think the car being so low helped reduce the damage. Not much room for the DS to bounce around between the tunnel and the exhaust. You can see where it spun on the tunnel a bit but didn't really penetrate.
The pipes obviously need some help. I think I am going to try and mend them myself and if I don't like the outcome keep bugging Holley to send me a replacement center piece.

Re: New to this Section- First LS Swap
Thankfully not. Both U joints were still where they were supposed to be. The yolk on the DS side snapped on the back, and I guess the u joint cap clips on the front u came off and the caps flew out. Looks like the center snapped and it spun for a split second and then got ejected off both u joints and fell the floor. Otherwise I would probably have a lot more damage.

Re: New to this Section- First LS Swap
I'm not sure if the Spohn transmission cross member drive shaft safety loop would have helped at all in this instance. Even if you were driving it might not have helped much in this case. I tend to believe that a well chosen drive shaft is money better spent than a safety loop.

I have a PSC shaft on order already, should ship out on Monday. 3" steel with a forged yolk, supposed to be good to 700.
I'm looking at the Spohn DS loop and I'm thinking it wont fit with the exhaust. I'll probably get under mine and measure over the weekend to make sure, but I don't think it is going to work. Will probably have to wait to do inner SFCs and fab something up.

Re: New to this Section- First LS Swap
Well it is "done". Need to get some better pictures, it was too sunny and they all kinda washed out with reflection. Gonna have to break out an actual camera. Still have a lot of cleaning and polishing and redoing of some stuff I messed up along the way, but mechanically it is there.
Holley was nice enough to make me just the center exhaust piece to replace the damaged one. Awesome customer service, they went above and beyond for me.
AC and heat are both hooked up and operational. This I how I plumed everything. Happy with how it came out aside from the suction line. Originally I had a 90 on the accumulator side but it made the hose kink too much. I might be able to change the compressor side to a 45 and just run it straight to a 90 on the accumulator instead of running under the heater hoses.
Ac is blowing at like 40 degrees, but for some reason my high side was only getting up to 50 psi after 4 cans of 134. Not sure if the gauges are messed up or something else is going on, it held vacuum good though.
Brakes have felt good until I as going putting it back in the garage yesterday. Turned to the left while braking and the pedal went to the floor. This seems to have happened previously too. I'm thinking I might be making something loose when turning and the pressure from the brake system then cracks it open a bit. Not sure, gonna keep messing with it.

Re: New to this Section- First LS Swap
Nice job good example of how nice third gens can be. What brakes do you have on it? I have the big brake LS brakes on mine and when the brakes are about 2/3rds worn they do that because the banjo fitting contacts the lower control arm and cracks the seal on the fitting. I'm going to try to see if the control arm can be modified to either limit steering by 1/4" or clearance the contact spot on the control arm.

Re: New to this Section- First LS Swap
C4 HD 13" on the front and rear discs, same ones on 1LE/4th gen/C4 etc..
It seems like the left rear is the one always burping air out, but not sure where it is coming in at. I didn't bleed the fronts last time and it improved until this. So I think it is the backs somewhere, either a body shift is causing a leak on the line going back there or possibly the same issue you have with the back brakes, not sure what it would contact back there though.
It is intermittent so always the hardest stuff to diagnose.

Re: New to this Section- First LS Swap
My issue was with the front brakes. When the wheel is turned to the lock left or right the banjo fitting on the left or right contacts the control arm (front) and causes a leak at the fitting.

Re: New to this Section- First LS Swap
I dunno still confused, no air out of the right rear. Double checked front bearings and clearance behind the rotors, can get a whole hand behind the caliper and the control arm.
Drove around a bit checking braking going left right and straight. Id definitely seems like the pedal pushes in further when I brake while turning left SOMETIMES. Could be imagining things.. could be vacuum pre load or something too since I'm not running a vacuum bulb. Guess I'll tear back into stuff this weekend.

Vacuum bulb (the orb) has nothing to do with it only for cruise control.

Re: New to this Section- First LS Swap
I don't see the engine making excessive vacuum, it really sounds like some kind of hydraulic issue to me. Since I removed my vacuum cruise control and the orb in favor of a digital cruise control from a later model when I start running mine some issues may rise but I don't see braking being a part of it.
