    Coolant Issues

    Hello everyone. Back again for another chapter of why I can't get my LB7 back on the road after throwing over $13k at it in performance parts just to make it reliable without actually making any power lol Just last night I finished putting the truck back together after replacing the injector...

    Well, figured I'd come in here to give this thread a closing. The entire issue was the SCD hold-downs. I installed new billet hold-downs from Industrial Injection and the truck fired right up. This time, no smoke from the PCV or oil filler neck and no loud tapping noises from inside the head...

    Well here's something interesting. Got done pulling all the SCD hold-downs earlier and found #8 about to break, but with a completely different failure area from the rest. I thought that of the second batch they sent only 7 and 6 had failed because those were my cylinders with low compression...

    Thanks Brad! Really appreciate you man. If it wasn't for your help I woulda been dead in the water tackling this project. I'm looking forward to finally being done with these hold-downs from SCD and just getting a product that works. Sent from my SM-S908U1 using Tapatalk

    Well, I've been busy so hadn't been able to get to this, but as I figured.... broken hold downs again. I took some pictures of #7 before pulling the nut and injector for those of you that know more than I regarding metal work. From these pictures any other thoughts? These things have been...

    Damn, thanks for all the great info! That's a pretty sick hobby you have there. Everything is on pause right now for the holidays, but I'm certain my vendor will help me out. I've been getting help from BDSankey for everything relating to this truck and he hasn't let me down. He's the one that...

    If that's how its supposed to look then there's definitely something wrong with the metal in these cause it looks nowhere near that smooth... check out this better closeup photo of one of them. Sent from my SM-S908U1 using Tapatalk

    Yeah same man. All I'd ever heard out of SoCal was: top notch stuff, best in the business, top shelf, etc. That's probably why I made the mistake of buying the motor. It never occurred to me that a solid metal part from SoCal that they claim has seen engines built to 1,700+ hp would fail at idle...

    The kit says to torque them down to 55 ft lbs. Factory value is 37 ft lbs. I torqued it to the 55 spec because the kit also comes with a stud and nut set also. I dont remember for sure if they came in ARP packaging, but I think they did cause the grease is also ARP. Sent from my SM-S908U1...

    Sure thing! All 4 that have broken from the first set. Sent from my SM-S908U1 using Tapatalk

    Nah, I know those are all there because I've seen them every time I've had the valve covers off. And even if one had somehow come off and I hadn't noticed, that would explain maybe one hold down constantly breaking, but I'm having this issue over all cylinders. Sent from my SM-S908U1 using...

    Indeed you did....really wish I woulda listened to you too. I trusted the SCD name and the fact that I had billet hold downs and listened to others, including a local shop, beating the cracked-piston drum. Now I have an LB7 pull-out sitting in my garage for no damn reason, but that's my own...

    Figured I'd come back and update this thread with my findings for anyone else that happens to be in this predicament. I ended up tearing back into the truck and found that my brand new SoCal Diesel injector hold down on cylinder 7 had snapped clean in half. The injector had lifted and was...

    Yeah I figured. Whatever is in there is gonna absolutely suck. So before I go do that I'm gonna take a break from this truck and finish my two Jeep projects. Gonna probably sell those to recoup some coin to help out with the crap show in #7. Sent from my SM-S908U using Tapatalk

    Not hard at all. I'm not one to finish installing new parts and dog it without allowing some settling time first. I just cruised around the block and came right back in cause I noticed the oil leak from the drain line. Didn't even do more than like 45 mph. Sent from my SM-S908U using Tapatalk

    Thats what I figured, but what I dont get is how does an engine just develop a cracked piston while idling?? I went back and found the blow by test from when I first bought the truck and it 100% did not have that. And all I've done since I did the top end is idle it, and when it first fired up...

    Well, I believe I have reached the end of the hope road here. I now have blow by that wasn't there before tear down, and was not there when I first fired up the truck. I started the truck back up after fixing the oil drain line leak and after about 2 minutes of running it started blowing smoke...

    Well good news and bad news... good news is that I dont have a motor with low compression on all cylinders... The bad news is that I have a motor with 400-410 psi of compression on all cylinders except for number 7 that has 300..... How bad am I screwed? Am I in bent valve or cracked piston...

    Well here goes fixing my last leak. I knew it was gonna be one of the damn gaskets shifting on me. Posting this in case it can help someone in the future. Red circle is residual oil on the drain pipe that tells me the leak is coming from the top gasket and not the lower, and the arrow is...

    Number 7 is also where I was hearing that loud tapping noise from. Not the intake one, but the one that started after it running for a bit. Sent from my SM-S908U using Tapatalk
