I just used the diamond pre cups in the reman heads. I should have it running tomorrow a friend and I dropped the engine in tonight just gotta finnish hooking up all the little things. I will post a video of the first start tomorrow or Sunday

Interesting was it hard to plumb in the propane?

Yup there is powpos and reggies in lacombe. Your a little over 2 hours south of me. Also thanks for the picture buddy. I will try that when I go through everything.

Thanks for the responce Jifaire. I'm gonna pull the truck to the shop next week and go right through it. I'm in the process of installing my new engine in the white truck so it's pretty busy around here. Where abouts in Alberta are you located?

Give the number a call. I just asked him if he can make that pump put out anymore then what it does from the factory. He said it can be calibrated to put out more to a certin extent before they start to run away in the upper rpms. Im pretty sure it can olny be turned up when it's out of the...

How hard is it to swap the steering colum? I just asked a friend who has experience in body shops. He said you need a special tool for the removal and installation. Also what kinda time frame am I looking at for the swap? And for the interior lights im not to sure if they work or not buddy. It's...

The shop is http://www.centraldieselinjection.com/ located in red deer alberta. Art has been building these pumps since the mid 90s he knows them really well. Im sure if you have any questions about them he would gladly help you.

I put my 929 back in service with these big old cracks got 30,000km on it right and now already over heated it twice lol both heads had cracks the same as yours

I swapped my spare ECM into it already with no results. I called parts source and a local supplier they were in that $246-$253 range. Yeah I had the same reaction about it being that much. I'm gonna try source out some other supplyers. But if I can use a 1997 ignition switch would be just great...

Really? But it still cranked over and over? I'm pretty sure that's not the issue with mine but I will double check to be sure

I was driving home the other day and my truck just died. It cranks and cranks but no start. I have eliminated the PMD and the ECM being bad. Also checked my grounds on rear passenger head and all fuses seem okay. Now from reading it seems like I have a bad ignition switch. Now I don't feel like...

Here is what you get from running a bad injector for extended periods of time on a duramax.

Interesting I always thought the whole LB7 gen was prone to head gasket problems from all the early failures I read at DP and the LLY was better but not completly fixed. I know GM has an up dated head gasket for the LLY now..... That with head studs fixes the problem for good...... Also how long...

Supposobly the most up dated and last number GM had after the 5521. Im curious to see how well it works. I had him calibrate it during the rebuild to put out the most fule possible with out running away.

im running the newest pump out there. I was considering trying the 5068 but i would half to send the chip back down to buddy for re tuneing and what not so i just decided to use a more common one. I also bought a new pmd with this pump its the grey one. I wonder if it will be any better....... I...

Goin to pick up the new injecion pump tomorrow! should be able to make a good dent on it this weekend and get ready to install next week if all goes well

2004 so thats the LB7 then. Unless its the 2004.5 witch would be the LLY.... but they dont have injector problems like the LB7s. If i were you i would replace the injectors in the duramax yourself it will probley cost around $2000 and add a seconday 2 micron fule filter it will keep them good...

Congrats on the truck, what ever happend to your 2008?

Try unplug the connectors on the top of the injection pump be sure there is no corrosion or water in them. I got code 17 and 18 and couldent do a TDC relearn until I tinkered with the harness. Been working fine for 2 months now. And X2 for buddy. He knows the OB1 very well
