    Duramax LLY Missing?

    I'm not sure who the manufacturer is on the injector. I know it is a bigger company. My engine builder is the one who installed them. Burn down I will try that ground as I don't think I have tried that one, my miss is weird, I have a garret powermax (loud turbo) and you can hear it cutting out...

    Duramax LLY Missing?

    Do note I did go for the remanufactured injectors and not new ones. I did not think I would have this kind of trouble. Going to contact manufacture and see if I can pay difference for new ones. I been kinda looking for ones to give better mileage. I'm still rocking my stock transmission.

    Duramax LLY Missing?

    Good suggestion there, forgot to mention I have done all wiring. I have fixed the known bad spots and checked all wiring. I can check that one off the list. It is weird guys cause it runs and drives fun it is just the idle in park or not in gear. If i put it in drive it will clear up.

    Duramax LLY Missing?

    No, number 5 cylinder valve was stuck and the piston was smacking it causing for the rebuild. The cause I believe was cause of 3 months prior my turbo went out and had only 3 quarts of oil left in it. She is 5k miles to Florida and back but ya.

    Hey guys, need some expert advice. My truck motor has been rebuilt. I got it head studded and heads redone and re ringed Pistons and etc, stock rebuild. I had all 8 injectors replaced as well. Now I got it back and it had a miss in idle. I bought a cts2 as well to see everything instead of...

    LLY piston hit valves spun bearings recommendations?

    Ok will see then. Everything is going to machine shop Monday. Hopefully get her back in a month. It has been a long summer without her. Thanks for all the suggestions. I just want to make sure the motor will last. The 190k just seems premature for big failure to me.

    LLY piston hit valves spun bearings recommendations?

    Yes doing the head studs for sure. I was told the crank was not the strongest in the LLY motor and another stock Duramax is stronger such as the lbz or lmm. Not sure which. A machinist told me that. Yes I am purchasing all new LLY pistons. I am pretty much going to have a new motor it seems but...

    LLY piston hit valves spun bearings recommendations?

    I'm not talking sled pulling or drag racing parts. With new parts and to do the whole motor I'm looking at 7500 that's including honing, valve job, 8 Pistons, piston rings, rods and new crank, head studs. If I do bare minimum it is like 6200. My question I guess is should I not gimp out on this...

    LLY Build, bare necessities

    Nice kits, he only told me 2k to start on the complete build including further diag. He said it would take a couple weeks for the machine shop to get their part done. I told him I understood having that kind of money tied up until I pay him for the new stuff. Thanks for giving me a different...

    LLY Build, bare necessities

    If the core charge is only 500 probably still worth it to keep my motor I would think. Probably a good time to put gauges on and do a fuel pump on to help the cp3, thanks for all the help. I was thinking a rebuild would be cheaper. My negligence I guess.

    LLY Build, bare necessities

    Most junkyards so far looking like 3-4 k for 100k miles. I would like to find one that does not require a core charge. Definitely buy a warranty from the junk yard though. Thanks for your help thunder

    LLY Build, bare necessities

    Thanks for the tip on Hicksville Bac, I will check that website I use to use it when I worked at a higher used dealership. Seems it is all unanimous that no one thinks j should rebuild the motor for what I do and even the 5-600 hp mark. Thanks guys

    LLY Build, bare necessities

    Alright, well I am hoping I don't have the same problem but with your guys help it sounds like we figured it out. It was cause of the oil starvation. I'll call Hicksville and see what a LLY cost and get it studded. Any idea on what a motor will cost? I just seen an ad on Craigslist and motor has...

    LLY Build, bare necessities

    Turbo went bad in January of this year. I know he is used to seeing sled pullers and mine is more stock then others. I read here those rods are the same. He had told me his machine shop told him the lb7 are more stout. I questioned him in it and he said he would check into it. I am thinking NJ...
